Standard Guide for Measuring Electrical Contact Intermittences

Importancia y uso:

4.1 This guide suggests techniques to evaluate intermittences in a contact pair while it is subjected to simulated or actual environmental stress. Such measurements are a valuable tool in predicting circuit performance under these stress conditions and in diagnosing observed problems in circuit function under such conditions.

4.2 This document is intended to provide some general guidance on the best available practices for detecting, quantifying, characterizing and reporting short duration intermittences in circuits containing electrical contacts. Certain environmental stresses such as mechanical shock, vibration or temperature change may cause intermittences. These measurement procedures include methods applicable to contacts operating under various conditions in testing or in service.

4.3 Practice B615 defines methods for measuring electrical contact noise in sliding electrical contacts. In contrast Guide B854 provides guidance to the various methods for measuring similar phenomena in static contacts.
