IEC 60533, “Electrical and electronic installations in ships – Electromagnetic compatibility (EMC) – Ships with a metallic hull,” has been updated. The new Edition 3.0 is available now from Document Center Inc. This update replaces the previous Edition 2.0, which is now obsolete.
The IEC 60533 centers on the control of harmful electromagnetic emissions. This is to prevent the possibility of other equipment being influenced by the installation in question. It specifically looks at ships with metallic hulls, since that structural formation can attenuate electromagnetic disturbances from outer deck environments to inner deck ones, and vice versa. And it also reviews special risks like lightning strikes, electromagnetic radiation from radio transponders and transients from the operation of circuit breakers.
The new IEC 60533 update is a significant change from the previous edition. Updates include the following:
- An expanded introduction
- Reduction of the scope of the standard to ships with metal hulls only (reflected in the updated title of the standard)
- Updates to the referenced documents section
- Clause 5.1 has a further explanation of in-situ testing
- Tables 1, 2 and 3 are updated (the numbering of the CISPR standards)
- Annex B has had a title change
- Requirements on cable routing in Annex B have also changed
- There’s a new Annex C on EMC test reports.
If you need more exacting information on the changes in this standard, there is a redline edition available. Here you’ll see all the modifications that were made to the previous Edition 2.0.
