ASTM F1598-95

Standard Test Method for Determining the Effects of Chemical/Solvent Exposure to a Membrane Switch/Graphic Overlay (Spot Test Method)

SCOPE
1.1 This test method covers the testing of any surface that may be exposed to liquid chemical(s).  
1.2 This test method is not designed for immersion testing conditions or material edge attack.  
1.3 This test method is designed for evaluation of visual changes. In certain instances physical (non-visual) changes may occur and functional testing may be appropriate.  
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.  
1.5 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.
