ASTM-F2114 › Standard Guide for ASTM Standard Test Methods, Standard Practices, and Typical Values of a Membrane Switch (Withdrawn 2009)
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
1.1 This guide contains a list of the current test methods and practices generated by Subcommittee F01.18 on Membrane Switches along with typical values for specifying certain performance characteristics of a membrane switch.
1.2 As a minimum, for any particular membrane switch, the values for the required characteristics should be specified.
1.3 Additional performance characteristics may be required and should be specified accordingly.
Significance and Use
In establishing guidelines for specifying a membrane switch, it is important to allow application design engineers to base their decisions on requirements using known reasonable, achievable performance levels.
Over-specification increases cost and complexity; under-specification risks not meeting performance criteria.
