ASTM F925-97

Standard Test Method for Resistance to Chemicals of Resilient Flooring

SCOPE
1.1 This test method provides a procedure for determining the resistance of resilient floor covering to surface deterioration when exposed to various chemical reagents. This test method is not intended as a staining test nor as a method to judge surface and appearance restoration of the sample after exposure to the chemical reagent.  
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
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.  Specific precautionary statements are provided in Section of this test method.
