IEC 60092-350 General Construction and Test Methods Guide

Every IEC 60092 shipboard cable standard stands on one foundation: IEC 60092-350, the general construction and test methods document for power, control and instrumentation cables on ships and offshore units. Where the part standards — 353 for power, 354 for medium voltage, 376 for control — each cover a specific voltage class, -350 defines the shared rules of construction, materials and verification that all of them reference. Understanding -350 explains why shipboard cables are built the way they are, no matter which part number appears on the datasheet.

What This Standard Covers

IEC 60092-350 defines general construction and test methods of power, control and instrumentation cables with rated voltages 150/250V up to 18/30kV for shipboard and offshore electrical installations. It specifies the common rules for conductors, insulation systems, sheathing, armouring, dimensional requirements and the test framework applied before any part-specific requirements are added. Fire performance is deliberately referenced to the IEC 60332, IEC 60754 and IEC 61034 families rather than defined inside -350 itself, and fire resistance testing points to IEC 60331.

Where It Fits in the Series

• IEC 60092-350: general construction and test methods — the base document for all cable parts

• IEC 60092-352: low voltage shipboard power cables up to 1kV, transitioning into -353

• IEC 60092-353: power cables for rated voltages 1kV and 3kV

• IEC 60092-354: medium voltage power cables from 3.6/6kV to 18/30kV

• IEC 60092-376: control and instrumentation cables rated 150/250V

• IEC 60092-360: insulating and sheathing materials, including SHF1 and SHF2 halogen free compounds

Key Requirements

• Conductors: stranded copper per IEC 60228, class 2 for fixed power cables and class 5 for flexible constructions

• Insulation and sheathing materials: defined per IEC 60092-360, with halogen free SHF1 and SHF2 compounds the normal choice for new shipboard installations

• Construction rules: core identification, laying up, bedding, armouring and outer sheath applied consistently across all voltage parts

• Test framework: electrical routine and type tests, dimensional checks, and mechanical verification common to all parts

• Fire behavior: referenced to IEC 60332 for flame retardance, IEC 60754 for halogen content and IEC 61034 for smoke emission

• Fire resistance: referenced to IEC 60331 for circuit integrity constructions

How It Affects Cable Construction

Because every part standard references -350, the base document effectively defines the DNA of shipboard cable: tinned or plain copper conductors, halogen free insulation and sheath systems, and the layered construction of bedding, optional armour and outer sheath familiar from any marine cable schedule. When a datasheet states "IEC 60092-353" or "IEC 60092-376", the underlying construction and test discipline comes from -350, with the part number adding voltage-specific insulation thickness and electrical test levels.

Common Mistakes

• Quoting -350 as a product standard. It is a general methods document; procurement should cite the applicable part number such as -353 or -376 together with -350 for the framework.

• Assuming -350 includes fire performance. Flame retardance, halogen free and low smoke properties are tested to their own IEC families; a cable built to -350 alone carries no fire claim.

• Ignoring material grades. SHF1 and SHF2 are both halogen free but behave differently in temperature and mechanical duty — the choice belongs in the specification, not the habit.

• Mixing edition years. Classification society type approvals cite specific edition years of -350 and its parts; a mismatch between datasheet and certificate edition can fail survey review.

FAQ

Q1: Is IEC 60092-350 a product standard?
No. It defines general construction and test methods shared by the part standards. Specify the relevant part such as IEC 60092-353 for 1kV power cables, with -350 implied as the framework.

Q2: Which IEC 60092 part applies to control cables?
IEC 60092-376 covers control and instrumentation cables rated 150/250V, built on the -350 framework.

Q3: Does IEC 60092-350 define flame retardance?
No. Flame retardance is tested per IEC 60332-3 categories, halogen free per IEC 60754 and low smoke per IEC 61034, with fire resistance per IEC 60331.

Q4: What conductor classes does IEC 60092-350 use?
Class 2 stranded copper for fixed installation power cables, and class 5 for flexible constructions, both per IEC 60228.

Q5: How do I specify a complete shipboard power cable?
