Scope

1.1 This test method covers the determination of capacitance(s) of a membrane switch.

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.

Significance and Use

Capacitance testing is useful for design verification, quality control of materials, and workmanship.

High capacitance may interfere with the reliable performance of interface electronics.

Specific areas of testing are, but not limited to:

Conductor/dielectric/conductor crossing point,

Close proximity of conductors, and

Any other conductive surface such as shielding or metal backing panel.
