BS EN 2349-407 is a standard that covers testing relays for cold, low air pressure and moist heat conditions to ensure operational stability and safety in varying environmental conditions.
BS EN 2349-407 specifies a method for testing the capability of relays to withstand cold, low air pressure and moist heat.
BS EN 2349-407 for relays with plug socket holders only. BS EN 2349-407 shall be used together with EN 2349-100.
BS EN 2349-407 on testing relays for cold, low air pressure and moist heat conditions applies to:
Relays are used to employ a tiny current to control the flow of big currents. In aerospace applications, the environmental conditions can quickly change depending on the weather and operations. The equipment needs to function properly in those changing conditions to ensure safety and durability in aerospace applications.
BS EN 2349-407 provides users guidance on a method for testing the capability of relays to withstand cold, low air pressure and moist heat conditions. BS EN 2349-407 also provides users with mounting and procedure for the method, enabling users to do the method correctly.
With obedience and compliance to BS EN 2349-407, users can test and assess relays for varying environmental conditions such as cold, low air pressure and moist heat to ensure operability, safety, and prevention of hazards in aerospace applications.
