Scope

1.1 This test method covers the determination of the electrical resistivity of a conductive material as used in the manufacture of a membrane switch.

1.2 This test method is not suitable for measuring force sensitive conductive materials.

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

1.4 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.

Significance and Use

Resistivity is useful to suppliers and manufacturers as follows:

3.1.1 when designing membrane switch interface circuitry,

3.1.2 when selecting the appropriate conductive material,

3.1.3 for conductive material quality verification, and

3.1.4 for conductive material cure optimization and quality control.
