ASTM B497-00(2006)

1.1 This guide describes recommended procedures to accurately measure voltage drop across current carrying contacts and the parameters to be documented in order to effectively record the results. Such contacts normally carry current greater than 1 amp. The applicability of these procedures to contacts carrying smaller currents should be evaluated prior to application to such devices. Contacts carrying small current may also be evaluated using Test Method B 539 to measure contact resistance.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 6.
