ASTM B63-90(2001)

1.1 This test method covers the determination, to a precision of 2%, of the electrical resistivity of materials used in resistors, heating elements, and electrical contacts, as well as products of powder metallurgy processes which are used for other purposes.

Note 1--For determining the resistivity of electrical conductors, see Test Method B193.

1.2 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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
