(Test Method)Standard Test Method for Deflection of Resilient Floor Tile
Standard Test Method for Deflection of Resilient Floor Tile
SCOPE
1.1 This test method is used to determine the deflection of relatively rigid resilient floor tile such as vinyl composition tile.
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.
