ASTM F2073-14

3.1 Destructive and non-destructive tests characteristics must be evaluated to ensure the membrane switch will operate and survive the application it was designed for. It is not feasible for all tests to be performed on each membrane of a production lot. However, there are some non-destructive tests that must be performed on each switch assembly to ensure 100 % functionality and checking each i/o point for unwanted electrical continuity to any other i/o point is one of these characteristics.

1.1 This standard establishes a test method for detecting unwanted electrical shorts in a membrane switch.

1.2 Since this is a non-destructive test, it can be performed on a membrane switch that is going to be mounted and used in its intended environment.

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