EN 2591-7301:2001

Overview

EN 2591-7301:2001 is a European standard developed by the European Committee for Standardization (CEN) under the Aerospace series. This standard focuses on test methods for electrical elements, specifically addressing the temperature endurance of couplers used in aerospace electrical and optical connections. It is designed to be applied alongside EN 2591-100, which covers general test methods for these connection elements.

The aim of EN 2591-7301 is to establish a reliable and reproducible procedure for evaluating the ability of couplers to maintain performance under prolonged exposure to elevated temperatures simulating operational aerospace environments. This ensures durability, safety, and optimal functionality of electrical connection components critical for aerospace applications.

Key Topics
