Doplňující informace
| Significance and Use | ||
|
4.1 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. 4.2 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. 1.2 The values stated in inch-pound
units are to be regarded as standard. The values given in
parentheses are mathematical conversions to SI units that are
provided for information only and are not considered standard.
1.3 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. |
