Description

Significance and Use

In the case of materials for resistors and heating elements, a knowledge of resistivity is important in determining whether wire or strip of a specified area of cross section and length will have a required resistance. It serves as one basis for the selection of materials for specific applications and its measurement is a necessary acceptance test for resistance materials.

In the case of materials for electrical contacts, the measurement of resistivity can serve as a test for uniformity of materials of nominally the same composition and structure.

1. Scope

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 B 193.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
