Small craft — Electrical systems — Alternating and direct current installations — Amendment 1
2Expert Interpretation
An in-depth analysis of the revisions to the ISO 13297:2020/Amd.1:2022 standard for small ship electrical systems, covering key technical changes such as updates to the IEC 60309-2 standard and changes to user manual requirements, and providing implementation recommendations for AC/DC system installation compliance.
Core content of the standard revision
| Revision items | Original standard requirements | Revised requirements |
|---|---|---|
| IEC 60309-2 reference | 1999 edition | 2021 edition |
| User manual specification | Mandatory reference to ISO 10240:2019 | Changed to general requirements + notes |
Details of key technical changes
1. Electrical connector standard upgrade
The entire document will unify IEC 60309-2 references updated from 1999 Edition to 2021 Edition, affecting:
- Clause 23.1 Connector Specifications
- Appendix D.1 Graphical Notation
2. User Manual Requirements Adjustment
Delete the normative reference to ISO 10240:2019 and replace it with:
"A user manual containing the following should be provided on board:
- System operation and maintenance instructions
- Wiring diagram with wire identification
- Fuse/circuit breaker parameters
- Power supply data details"
Implementation Recommendations
Ship Manufacturers
- Immediately update the electrical connector selection criteria to IEC 60309-2:2021
- The user manual is compiled with a modular structure to ensure that it contains the 6 types of core information
Inspection agencies
Focus on:
- Whether the AC distribution box of newly installed ships complies with the new version of the IEC standard
- Whether the user manual contains the revised mandatory content
Analysis of standard evolution
This revision reflects two major trends:
1. Standard coordination: Keeping up to date with IEC standards
2. Implementation flexibility: Changing the user manual from a mandatory reference to a principled requirement
