ASTM D3430-95

Standard Test Method for Clarity and Yellowness of Liquid Water-Based Clear Floor Polishes

SCOPE
1.1 This test method covers measurement of the degree of clarity and depth of yellowness of water-based clear floor polishes.  
1.2 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.
