On 6 May 2026, the International Electrotechnical Commission (IEC) officially published IEC 60092-352:2025 — Electrical Cables for Ships — Part 352: Low-smoke, Halogen-free, Flame-retardant Cables. The standard explicitly lists China’s GB/T 39560-2021 as a ‘Technically Equivalent Standard’ (TEP) in its official TEP List. This development is particularly relevant to marine cable manufacturers, shipbuilding supply chain stakeholders, and export-oriented electrical equipment exporters targeting EU, Middle Eastern, and Latin American markets.

Event Overview

The IEC released IEC 60092-352:2025 on 6 May 2026. The document formally recognizes GB/T 39560-2021 — China’s national standard for low-smoke, halogen-free, flame-retardant shipboard power cables — as technically equivalent under the IEC’s TEP framework. As confirmed in the published standard, this recognition applies to the scope covered by IEC 60092-352:2025 and enables Chinese manufacturers including Far East Cable and Hengtong Optic-Electric to bypass redundant type testing when seeking certification for export to regions adopting IEC 60092-352:2025.

Industries Affected

Direct Exporters of Marine Cables

These companies supply finished shipboard cables to overseas shipyards, classification societies, or system integrators. Recognition of GB/T 39560-2021 as a TEP reduces certification lead time by ~40% for markets aligning with IEC 60092-352:2025 — notably the EU (via EN 50525-2-81 adoption), Gulf Cooperation Council (GCC) countries, and select Latin American jurisdictions accepting IEC-based conformity assessment.

Cable Component & Material Suppliers

Suppliers of LSZH (low-smoke zero-halogen) insulation compounds, conductor stranding services, or jacketing materials may face increased demand consistency requirements. While GB/T 39560-2021 alignment does not automatically extend to upstream material specifications, downstream certification efficiency gains increase pressure for stable, traceable, and IEC-aligned raw material documentation — especially for flame propagation and smoke toxicity test reports.

Marine Equipment Integrators & System Builders

Companies assembling propulsion control panels, power distribution units, or integrated bridge systems that incorporate certified cables must verify whether their existing cable procurement records reference GB/T 39560-2021-compliant products. If so, they may now streamline third-party verification steps during classification society audits or flag-state inspections where IEC 60092-352:2025 compliance is declared.

Conformity Assessment & Certification Bodies

Notified bodies and accredited testing laboratories operating in IEC-aligned markets may adjust internal workflows for cable evaluation. Where applicants submit GB/T 39560-2021 test reports from CNAS-accredited labs, these bodies are now permitted — per IEC 60092-352:2025 Annex B — to accept them as valid evidence without retesting, provided scope and methodology match the IEC standard’s requirements.

Key Considerations and Recommended Actions

Monitor official implementation guidance from national standards bodies

While IEC 60092-352:2025 has been published, national adoption timelines (e.g., EN conversion in CENELEC, SAC alignment updates) remain pending. Stakeholders should track announcements from SAC (Standardization Administration of China), DIN, BS EN, and GCC Standardization Organization to confirm effective dates and transitional provisions.

Verify product scope alignment before assuming equivalence

GB/T 39560-2021 and IEC 60092-352:2025 do not share identical voltage ratings, temperature classes, or mechanical test thresholds across all cable types. Companies must conduct side-by-side technical review — focusing on conductor construction, insulation thickness, flame spread (IEC 60332-3 vs. GB/T 18380.33), and smoke density (IEC 61034 vs. GB/T 17651.2) — before declaring equivalency for specific product lines.

Distinguish between formal recognition and market-level acceptance

TEP listing reflects technical comparability, not automatic regulatory approval. End-market acceptance still depends on local notified body discretion, classification society policies (e.g., DNV, LR, ABS), and port-state control interpretations. Exporters should proactively engage with target-market certification partners to confirm acceptance protocols prior to shipment.

Update internal documentation and test report referencing

Manufacturers currently referencing GB/T 39560-2021 in certificates, declarations of conformity, or technical files should revise references to include explicit linkage to IEC 60092-352:2025 TEP status — e.g., ‘Complies with GB/T 39560-2021, recognized as Technically Equivalent Standard (TEP) under IEC 60092-352:2025’. This supports smoother audit trails during customs clearance or post-market surveillance.

Editorial Observation / Industry Perspective

Observably, this TEP recognition functions primarily as an administrative efficiency signal rather than a de facto harmonization outcome. It confirms technical parity at the standard level but does not eliminate regional conformity assessment infrastructure or classification society-specific validation steps. Analysis shows that the impact is most immediate for Type Approval cycles — not for design freedom, material sourcing, or installation compliance. From an industry perspective, it signals growing interoperability between China’s maritime electrical standards and global frameworks, yet sustained attention is warranted as regional regulators translate IEC publication into enforceable national legislation.

Conclusion
This development marks a procedural milestone in international standard alignment for marine low-smoke cables — one that improves export efficiency for compliant Chinese manufacturers but does not alter fundamental technical or regulatory obligations. It is best understood not as a market access breakthrough, but as a targeted reduction in certification friction for a defined product category and set of destination markets. Stakeholders should treat it as an operational enabler requiring careful scope validation — not a blanket simplification.
