This standard method sets out a test procedure to determine the influence ofatmospheres containing hydrogen sulphide on the contact properties of contacts.

This standard method sets out a test procedure to determine the influence of atmospheres containing hydrogen sulphide on the contact properties of contacts made of-(a) silver or silver alloy; (b) silver protected with another layer;(c) other metals covered with silver or silver alloy; and to check wrapped or crimped connections made of the materials listed with regard to their continuity or effectiveness.In all tests, the major criteria of performance will be the change in contact resistance caused by exposure to the hydrogen sulphide containing atmosphere.
