Bending or creasing of membrane switches or their components can affect their visual appearance, mechanical integrity or electrical functionality. This practice simulates conditions that may be seen during manufacture, installation or use.

Bend or crease testing may be destructive, therefore any samples tested should be considered unfit for future use.

Specific areas of testing include, but are not limited to:

Membrane switch flex tails, and

Any component of a membrane switch that may be subjected to bending or creasing.

1. Scope

1.1 This practice establishes a method for the creasing or bending of any part of a membrane switch.

1.2 This practice can be used with other test methods to achieve specific test results.

1.3 The values stated in SI 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.

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