ASTM D4103-90(2002)
(Practice)Standard Practice for Preparation of Substrate Surfaces for Coefficient of Friction Testing
Standard Practice for Preparation of Substrate Surfaces for Coefficient of Friction Testing
SIGNIFICANCE AND USE
The reliability of any of the practices using panels prepared by these procedures may be dependent upon the manner and care in which the test panels are prepared. Having these practices in a single procedure eliminates the necessity for covering these details in all of the practices wherein the panels are used.
SCOPE
1.1 This practice covers procedures for the preparation of OVCT (Official Vinyl Composition Tile) and wood panels for subsequent use in tests to measure the coefficient of friction.
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.
