BS EN IEC 63522-34:2025

This standard BS EN IEC 63522-34:2025 Electrical relays. Tests and measurements is classified in these ICS categories:

• 29.120.70 Relays

IEC 63522-34:2025 This part of IEC 63522 is used for testing all kinds of electrical relays and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use. This document provides tests to ensure that a relay is suitable for use when subjected to contamination by fluids found in aerospace applications and similar. This test applies to RT III to RT V relays only.
