BS EN 4875:2020

This standard BS EN 4875:2020 Aerospace series. Surface treatments. Test method for measurement of electrical contact resistance is classified in these ICS categories:

• 25.220.99 Other treatments and coatings
• 49.040 Coatings and related processes used in aerospace industry

This document describes the electrical contact resistance testing method applicable to conductive and non-conductive coatings applied on test specimens made of conductive materials (unless otherwise specified) for aerospace applications. An objective of this practice is to define and control many of the known variables in such a way that valid comparisons of the contact properties of materials can be made.

This test may be locally destructive depending on the process tested.
