Professional cable manufacturer
There is no such thing as “an IEC 60092 cable”. IEC 60092 is a series under TC 18, and the cable requirements are split across it: one part fixes the general construction and the test methods, others fix the power, control, data and fibre cables at their own voltage ratings, one fixes the compounds, and one fixes how the cable is chosen and installed. This page maps the parts, reads the compound letters that end up in a shipboard type code, and shows which numbers on a data sheet the document actually fixes — and which it does not.
IEC 60092 answers to the part number first and the voltage basis second. IEC 60092-350 is the base: it carries the general constructional requirements and test methods for power, control and instrumentation cables with copper conductors on board ships and offshore units, at voltages up to and including 18/30 (36) kV. Sitting on that base are the product parts: IEC 60092-353 for power cables rated 0,6/1 (1,2) kV or 1,8/3 (3,6) kV, IEC 60092-354 for single- and three-core power cables from 6 kV (Um = 7,2 kV) up to 30 kV (Um = 36 kV), IEC 60092-376 for control and instrumentation circuits at 150/250 V (300 V), and IEC 60092-378 and -379 for optical fibre and symmetrical category cables. IEC 60092-360 carries the insulating and sheathing materials, which is where the letters on the type code come from — the SHF 2 sheath and the SHF 1 sheath are two different compounds in that document, not a quality grade. And IEC 60092-352 carries selection, installation and operating conditions: current carrying capacity and its correction factors, voltage drop, earthing of metal coverings, bend radius and penetration. A quotation that says only “IEC 60092” has told you none of that.
IEC Technical Committee 18 writes Electrical installations of ships and of mobile and fixed offshore units. The cable work is delegated to its subcommittee SC 18A, Electric cables for ships and mobile and fixed offshore units. That split is what produces the IEC 60092 series: the installation-level parts sit with TC 18, and the cable parts sit with SC 18A, which is why IEC 60092-350 through -379 read as a block while -101, -201 and -401 read as installation topics.
The series is built on a deliberate division of labour, and understanding it removes most of the confusion in a marine cable enquiry. One part fixes what the cable is at a given voltage and application (353 for 1 kV and 3 kV power, 354 for medium voltage, 376 for control and instrumentation, 378 and 379 for fibre and data). One part fixes the constructional details and the tests common to all of them (350). One part fixes the materials, and therefore the letters that appear in a type code (360). One part fixes how you choose and install it (352). And one part fixes the commissioning test of the finished installation (401).
The practical consequence is blunt. A specification, a quotation or a data sheet that says “to IEC 60092” and stops there has not told you the voltage basis, the compound family, the armour form or the fire performance. Each of those lives in a different part, and each is separately declared.
The table below lists the parts of the series that a cable enquiry actually lands on. The title column is the document's own title; the what it fixes column is what the scope of that part puts inside it. Nothing here is a paraphrase of a clause number — it is the published scope.
| Part | Title | What it fixes |
|---|---|---|
| 350 | General construction and test methods of power, control and instrumentation cables for shipboard and offshore applications | The constructional layers and the test methods that the product parts inherit. Copper conductors, fixed electrical systems, up to and including 18/30 (36) kV. |
| 352 | Selection, installation, and operating conditions of cables | Current carrying capacity and its correction factors, voltage drop, parallel connection, short-circuit capacity, screening, fire performance, electromagnetic-interference practice, earthing of metal coverings, bend radius, supports, penetration of bulkheads and decks. |
| 353 | Power cables for rated voltages 1 kV and 3 kV | Shipboard and offshore non-radial-field power cables with extruded solid insulation at 0,6/1 (1,2) kV and 1,8/3 (3,6) kV, including cables designed to maintain circuit integrity during a fire. |
| 354 | Single- and three-core power cables with extruded solid insulation for rated voltages 6 kV (Um = 7,2 kV) up to 30 kV (Um = 36 kV) | The medium-voltage power cable, single-core and three-core, with conductor and insulation screens. |
| 360 | Insulating and sheathing materials for shipboard and offshore units, power, control, instrumentation and telecommunication cables | The compound designations themselves — the letters that appear in a type code — and their electrical, mechanical and particular characteristics. |
| 376 | Cables for control and instrumentation circuits 150/250 V (300 V) | Control and instrumentation cables at their own low voltage rating, screened and unscreened. |
| 378 | Optical fiber cables | Fibre cable — which is why IEC 60092-350 explicitly excludes it from its own scope. |
| 379 | Symmetrical category cables with transmission characteristics up to 1 000 MHz | Structured data cable for shipboard and offshore installations. |
| 401 | Installation and test of completed installation | The commissioning test of the finished system rather than of the cable. |
A second detail worth knowing before the table is read as a warranty: manufacturers' data sheets in circulation still cite the older part numbers for materials. One marine cable catalogue lists its approvals line as IEC 60092/353, IEC 60092/350-351-359, IEC 60332/1, IEC 60332/3 Cat A, IEC 60754/1-2, IEC 61034/1-2. Part 351 covered insulating materials and Part 359 covered sheathing materials; the requirements now sit in IEC 60092-360, whose scope states in one sentence that it covers both the insulating and the sheathing materials. Seeing 350-351-359 on a data sheet is therefore not a different construction — it is an older citation of the same layer.
Everything above sits on IEC 60092-350. Its scope reads, in full: it provides the general constructional requirements and test methods for use in the manufacture of electric power, control and instrumentation cables with copper conductors intended for fixed electrical systems at voltages up to and including 18/30 (36) kV on board ships and offshore (mobile and fixed) units. Fixed systems here includes those subject to vibration or movement from the ship, but not cables intended for frequent flexing — those belong to IEC 60227 and IEC 60245, and their use on board is restricted to situations that do not expose them directly to the marine environment.
The scope then states, as a list, what the document does not cover: optical fibre, sub-sea and umbilical cables, data and communication cables, and coaxial cables. That list is the single most useful sentence in the whole series for anyone reading a specification, because it tells you when a document has been cited outside its own scope.
IEC 60092-350 also holds the definitions the other parts reuse — IEC 60092-353 says so explicitly, applying the terms given in IEC 60092-350 and in the IEC Electrotechnical Vocabulary (IEC 60050, part 461). Four of its definitions decide real arguments:
Three of the loose ends in a marine enquiry are the same three loose ends every time: the compound (which letter, from which part), the fire arrangement (which test, at which diameter and duration), and the braid (mechanical protection, earth conductor, or both). If your specification does not pin all three, ask for them in writing before the cable is made — or send us the specification and we will show you which of the three it leaves open.
For most shipboard power work this is the operative part. Its scope: shipboard and offshore non radial field power cables with extruded solid insulation, having a voltage rating of 0,6/1 (1,2) kV or 1,8/3 (3,6) kV intended for fixed installations. It adds one sentence that changes the commercial picture — cables designed to maintain circuit integrity during a fire are included. The object of the document is stated as three things: to standardise cables whose safety and reliability is ensured when installed to IEC 60092-352 or IEC 61892-4, to lay down standard manufacturing requirements and characteristics bearing on safety, and to specify the test methods for checking conformity.
The rated-voltage designation is worth reproducing because it is misread constantly. The standard method takes the form Uo/U (Um), where Uo is the rated power-frequency voltage between a phase conductor and earth or the metallic screen, U is that between phase conductors, and Um is the maximum value of the highest system voltage for which the equipment may be used. All values are RMS. The two standard ratings covered are 0,6/1 (1,2) kV and 1,8/3 (3,6) kV, and for the 0,6/1 (1,2) kV family a DC voltage up to a maximum of 1,5 times the AC voltage may be used, provided the voltage to earth does not exceed 0,9 kV. That is where the “1,5 kV DC” sometimes printed on a shipboard data sheet comes from.
Marking is fixed numerically. Marking counts as continuous when the distance between the end of any marking and the beginning of the next does not exceed 550 mm on the outer surface of the cable, and 275 mm in all other cases. Cores are identified by colours to IEC 60445 or by numbers.
The constructional clause does not give a single build; it gives a set of allowed builds and the order of their layers. That is the whole reason two cables sold as “IEC 60092-353” can look completely different in section.
| Form | Layers, in order | Note |
|---|---|---|
| Single-core unarmoured, unsheathed | Copper conductor → one layer of insulating compound, applied at an enhanced thickness equivalent to a combined insulation and outer sheath | For unarmoured use in an adequately protected environment. This is the form where the insulation is doing two jobs. |
| Unarmoured, single- or double-sheathed | Conductor → insulation → cabling → inner covering (optional; mandatory when a braided or metal-tape electrostatic screen is applied over the core lay-up) → electrostatic screen (optional) → inner sheath (optional) → outer sheath, one- or two-layer | The workhorse multicore form. |
| Armoured, single-sheathed, outer sheath only | Conductor → insulation → cabling → inner covering below the screen → electrostatic screen (optional) → inner covering (optional; mandatory for galvanised steel wire braid, and then extruded) → braid armour → outer sheath | Where an inner covering must be extruded, a taped bedding is not interchangeable. |
| Armoured, double-sheathed | Conductor → insulation → cabling → inner covering → electrostatic screen (optional) → inner sheath → braid armour → outer sheath | A note to this form warns that a thermoplastic inner sheath (ST 2 or SHF 1) is not compatible with the cross-linking technology of an elastomeric outer sheath. |
| Armoured, single-sheathed, inner sheath only | Conductor → insulation → cabling → inner covering → electrostatic screen (optional) → inner sheath → braid armour | The braid is the outermost layer. This is the form the corrosion sentence below is written for. |
One sentence in that clause is quoted in marine specifications more than any other, because it decides a purchase order: cables for installation in spaces where corrosion may occur — for example weather decks, wet locations, battery compartments, refrigeration rooms — should have an outer sheath over the braid, unless the braid itself is corrosion resistant. If your route includes a weather deck or a battery compartment, that sentence is the reason to specify an outer sheath rather than a bare braid finish.
Conductors and compounds are pinned down too. For cables rated 1,8/3 kV, only circular stranded compacted or non-compacted conductors with a minimum cross-section of 10 mm² are permitted. Insulation is a closed list per voltage: at 0,6/1 (1,2) kV the permitted types are EPR, HEPR, XLPE, HF 90 or S 95; at 1,8/3 (3,6) kV only EPR, HEPR and XLPE are permitted. If a quotation offers a 3 kV cable insulated with a halogen-free compound outside those three names, the compound belongs to a different document.
The fifth edition was published in June 2024 and replaces the 2016 fourth edition as a technical revision. The changes are listed in the document and are unusually readable for a spec update: references to IEC 60092-350 for general construction and test methods and to IEC 60092-360 for insulating and sheathing materials were updated; a subclause 5.10, Construction for special applications, was added; a Table 9 was added for the additional test on cables for installation between areas with and without explosive atmospheres; the IEC 60331-21 test requirement was deleted from Table 7; and the former Annex A on alternative enhanced insulation thickness for 0,6/1 kV was deleted.
Two of those five changes are easy to catch on paper. If a data sheet still offers an “alternative enhanced insulation thickness for 0,6/1 kV” as a standard route, it is quoting an annex that the 2024 edition removed. And the removal of the IEC 60331-21 requirement from Table 7 means a fire-resistance claim can no longer be justified by pointing at that table row alone — the fire test arrangement has to be named explicitly for the cable you are buying.
Almost every argument about a shipboard cable type code turns out to be an argument about material designations, and those designations live in IEC 60092-360. Its scope is one sentence: it specifies the requirements for electrical, mechanical and particular characteristics of insulating and sheathing materials intended for use in shipboard and fixed and mobile offshore unit power, control, instrumentation and telecommunication cables.
The materials are divided into three categories, and that division is the first thing to memorise:
| Category | Designations | Normal operation | Short circuit |
|---|---|---|---|
| Cross-linked insulating compounds | EPR | 90 °C | 250 °C |
| Cross-linked insulating compounds | HEPR | 90 °C | 250 °C |
| Cross-linked insulating compounds | XLPE | 90 °C | 250 °C |
| Cross-linked insulating compounds | HF 90 | 90 °C | 250 °C |
| Cross-linked insulating compounds | S 95 | 95 °C * | 350 °C † |
| Cross-linked sheathing compounds | SE / SH / SHF 2 | — | — |
| Thermoplastic sheathing compounds | SHF 1 / ST 2 | — | — |
Read the sheathing rows with care, because they are where the letters come from. SHF 2 is defined in the document's terms as a halogen-free rubber — a cross-linked compound in which the polymer is a polyolefin or an equivalent synthetic polymer, not containing halogens. SHF 1 is halogen-free thermoplastic — the same halogen-free rule, but a thermoplastic rather than a cross-linked material. Both are halogen-free. The difference between them is the cross-linking, and that difference is what the trailing digit carries. A third row, ST 2, is neither: it is defined as a thermoplastic compound based on plasticised polyvinyl chloride. So a specification that says “halogen-free sheath” without the designation has said less than it thinks; and a cable offered with an ST 2 sheath is not a halogen-free cable at all.
“LSZH” and “SHF 2” are not synonyms in a marine document. LSZH is a description of behaviour; SHF 2 is a designation whose definitions, test requirements and compound listing are held by IEC 60092-360. When a Marine type approval or a class surveyor asks what the sheath is, the answer expected is the designation from that document, plus the test tables the compound passes. If you build the same cable for a land project, the same principle holds — see our note on XLPE versus LSZH cable, where the two words are often wrongly treated as alternatives.
Some marine power cables are offered with an insulation and a sheath rated +120 °C, and a data sheet will print it next to the standard reference. Read it for what it is: in the documents above, the cross-linked insulating compounds listed for a 0,6/1 kV power cable are rated 90 °C normal operation, with the single exception of the silicone type at 95 °C. A 120 °C figure is a manufacturer's upgrade on a specific construction, demonstrated by tests that the maker can point to. It is a perfectly reasonable thing to buy — it is not a figure the standard sets, and a specification written to the standard should not assume it.
The fourth operational part, revised in October 2025, is the one that decides whether a cable of the right construction is still the right cable once it is on the ship. Its scope provides the basic requirements for the selection, installation and operating conditions of electrical cables for fixed electrical systems on board ships, at voltages up to and including Um 18/30 (36) kV, and it also covers symmetrical category cables and fibre optic cables. As with 350, it lists what it excludes: sub-sea and umbilical cables, telecommunication and radio frequency cables, and — a boundary worth noting — the selection and installation of cables for use on offshore platforms.
That last exclusion matters to anyone quoting for an offshore job. The document's own introduction records that guidance for the use and installation of cables for offshore applications is being prepared jointly and will be issued under the TC 18 maintenance team rather than inside 352. Meanwhile the cable part IEC 60092-350 does cover offshore (mobile and fixed) units in its scope. So the cable can be built to a shipboard document and still be installed under a different clause set offshore — a distinction that regularly surprises a first-time tenderer.
The clause headings are the clearest summary of what an installation is judged on, and they are worth reading as a checklist rather than as a list of topics:
The bend-radius figures, the current-carrying tables and the correction factors all live in the paid text of IEC 60092-352 (and, for older projects, in the annexes of its 2005 predecessor). We do not quote figures from a document we cannot read, so this page gives you the structure — which table exists, which rating it belongs to, which correction applies to which condition — and stops there. If a supplier hands you a bend radius, ask which table it comes from and which voltage rating it was read against; the two-table split in the 2025 edition exists precisely because one figure does not serve both.
The 2025 edition is a full review rather than a patch. The published changes: the part title changed; the document was reviewed end-to-end and matched against the whole IEC 60092-350 to -379 group; terms and definitions were added; technical requirements were added for installing symmetrical category cables with transmission characteristics up to 1 000 MHz; requirements were added for installing fibre optic cables; requirements were added for cables installed between areas with and without explosive atmospheres; and requirements were added for the special safety provisions drawn from the SOLAS regulations. Any of those six is a reason your existing installation note may need a re-read if the project is specified to the current edition.
The quickest way to check whether a marine cable offer is coherent is to list the standards it cites and ask what each of them is actually doing. There are typically five to eight, and they divide cleanly. The table below is the division — and the last column is the part that matters, because a datasheet that lists a standard is not thereby claiming to pass every test in it.
| Cited | The job it does | What it does not establish |
|---|---|---|
| IEC 60092-353 | The power cable construction and its tests, at 0,6/1 (1,2) kV or 1,8/3 (3,6) kV. | That the maker holds a type approval for the finished cable, or that the cable is fire resistant. |
| IEC 60092-350 | The general construction and test method layer the product part inherits. | Anything specific to the 1 kV or 3 kV ratings — 350 is the base, not the product. |
| IEC 60092-360 | The compound designation, for example XLPE insulation or an SHF 2 sheath. | That the finished cable passes a flame, smoke or halogen test. |
| IEC 60228 | The conductor class and its resistance limits. | Ampacity in a shipboard ambient — that is a 352 calculation, not a conductor property. |
| IEC 60332-1-2 | Vertical flame propagation of a single insulated wire or cable under a 1 kW pre-mixed flame. | Flame spread of a bunched tray. That is a IEC 60332-3 category test. |
| IEC 60332-3-22 | Vertical flame spread of vertically mounted bunched wires or cables, Category A. | Circuit integrity under fire — flame spread and continued operation are different questions. |
| IEC 60754 | The halogen acid gas content and the acidity by pH and conductivity. | Smoke density. Halogen content and smoke are measured by different rigs. |
| IEC 61034 | Smoke density of cables burning under defined conditions. | Halogen content. A low-smoke cable is not automatically a halogen-free one. |
| IEC 60811-404 | The method for the mineral-oil immersion test on sheaths, with the conditions taken from the SHF 2 row of IEC 60092-360. | The result. Citing the method is not the same as quoting the hours and the pass criterion. |
Two practical consequences follow. First, when a supplier says “the cable is flame retardant to IEC 60332-1-2”, that is a single-cable test — it says nothing about what a fully loaded tray of them does. Second, when a datasheet prints IEC 60754 and IEC 61034 as a pair, it is quoting two independent test families; a halogen-free claim depends on the first, a low-smoke claim on the second, and both are usually wanted in an enclosed space.
For a Chinese exporter or an overseas buyer comparing a marine enquiry against a land project, the useful mapping is at the layer level, not the document level. IEC 60092 does not replace IEC 60502, and neither replaces the Chinese GB/T 12706 series; the three sit side by side, each owning its own application. What can be matched is what each layer is made of.
| Layer | Shipboard (IEC 60092) | Land (IEC and Chinese) | Where the correspondence stops |
|---|---|---|---|
| LV power cable, 0,6/1 kV | IEC 60092-353 | IEC 60502-1; GB/T 12706.1 series on our YJV/YJLV 0,6/1 kV page | The construction layers correspond. The documents do not adopt one another. |
| MV power cable | IEC 60092-354, 6 kV (Um = 7,2 kV) to 30 kV (Um = 36 kV) | IEC 60502-2; GB/T 12706.2 and 12706.3 series, as on our medium-voltage armoured cable page | Radial field, screened construction in both systems; the rating ladders are not identical. |
| Control and instrumentation | IEC 60092-376, at 150/250 V (300 V) | GB/T 9330 control series and the instrument-cable families on our WDZ instrumentation cable page | The marine part works down at a lower rating; compare ratings before matching types. |
| Materials | IEC 60092-360 compound designations | Insulation and sheath compounds per the land standard in use | A designation from one document does not transfer as a designation to the other. |
| Installation rules | IEC 60092-352 | National wiring rules and the installation sections of the land standard | Different ambient basis and different grouping assumptions; do not carry a derating figure across. |
At the layer level the mapping is exact: plain annealed copper to a published class, an extruded solid insulation, a stated voltage basis, a fixed installation. A 0,6/1 kV XLPE shipboard cable and a 0,6/1 kV XLPE land cable are recognisably the same object in section. At the document level nothing is exact. The shipboard part adds a compound list, a marking-continuity rule and a special-applications subclause; the land standard answers a different set of questions. A type-test report against one system does not establish conformity with the other, and a project specified to a marine document needs evidence against that document or the national adoption named in the specification.
Cross-reference index
Shipboard cable is specified by the part that covers its duty, not by a single type code — which is why a marine data sheet cites four or five standards at once. If you need to know what the land-based equivalent of a given shipboard build looks like, enter the designation or the part number in the cross-reference index and read the shipboard family alongside the other five systems.
Everything above comes from documents we can read: the scope, the normative reference lists, the definitions, the constructional clause, the marking rule, the material categories and the conductor temperatures of IEC 60092-350, -352, -353 and -360, together with the IEC series listing and manufacturer data sheets for the same family, all listed in Sources. Where a part is not public, this page stops at the name: the insulation-thickness table, the current-carrying tables, the correction factors and the bend-radius tables are inside the paid text, so no figure from any of them is quoted. The 120 °C construction and the bending radius of a specific catalogue cable are presented as manufacturer figures, because that is what they are.
What the page does not do is approve an installation. It will not tell you that a given cable satisfies your vessel, your class society or your flag state — that depends on the exact construction, the compound, the declared fire arrangement, the edition the project is specified to, and the authority that will survey it. Bring us the specification, the voltage basis and the route, and we will work the comparison against a construction we actually build.
Send the IEC 60092 part the project is specified to, the voltage basis, the core count, the cross-section, the sheath designation and the installation route. We will come back with the construction it corresponds to and the points where the specification and the part disagree.

How this was written: every figure in this article is checked against the standard or datasheet listed in Sources before publication. Where a value is our own measurement, it is labelled as such.
It is the IEC series on electrical installations in ships and of mobile and fixed offshore units, produced by TC 18 with the cable work delegated to SC 18A. It is a series, not one standard. The cable requirements are split across it: IEC 60092-350 carries the general construction and test methods, -353 and -354 the power cables, -376 control and instrumentation, -378 and -379 fibre and data, -360 the insulating and sheathing materials, -352 selection, installation and operating conditions, and -401 the commissioning test.
IEC 60092-353. Its scope covers shipboard and offshore non-radial-field power cables with extruded solid insulation rated 0,6/1 (1,2) kV or 1,8/3 (3,6) kV for fixed installations, including cables designed to maintain circuit integrity during a fire. On top of that, the general construction and test methods come from IEC 60092-350 and the compound designations from IEC 60092-360 — so a complete 0,6/1 kV specification normally cites three parts, not one.
It is a compound designation from IEC 60092-360, not a quality grade. The document defines SHF 2 as a halogen-free rubber: a cross-linked compound in which the polymer is a polyolefin or an equivalent synthetic polymer, not containing halogens. SHF 1 is the halogen-free thermoplastic of the same family, and ST 2 is a third compound based on plasticised PVC — which is not halogen-free at all. So "halogen-free sheath" is less precise than the designation someone should be writing into the specification.
No. IEC 60092-353 says that cables designed to maintain circuit integrity during a fire are included in its scope — that is an inclusion, not a requirement on every cable. Fire performance is declared per product against the test arrangements in the document's test tables, and the 2024 edition removed the IEC 60331-21 test requirement from its fire-resistant table. Treat "fire resistant" without a named test arrangement, a flame temperature and a duration as an unfinished sentence.
Sometimes, and it is conditional. IEC 60092-350 defines braid armour and adds a note that where the rules of the applicable national, regulatory or approval body permit the practice, it is possible to use the braid armour as an earth conductor. A second note adds that copper-wire braid armour may also provide a limited collective electrostatic screen function, provided it is effectively earthed. Both are permissions subject to the body that will approve the installation, so the answer belongs in the project's earthing design, not in the cable datasheet.
No, and it says so. Its scope excludes the selection and installation of cables for use on offshore platforms, while the cable part IEC 60092-350 does cover offshore mobile and fixed units. The document's own introduction records that guidance for the installation of cables in offshore applications is being prepared jointly by SC 18A and TC 18 and will be issued separately. So a cable can be built to a shipboard document and still be installed under a different clause set offshore.
