ASTM F1304-08(2013)
(Test Method)Standard Test Method for Deflection of Resilient Floor Tile
Standard Test Method for Deflection of Resilient Floor Tile
SIGNIFICANCE AND USE
3.1 This test method measures a physical property associated with resilient floor tile's ability to conform to an uneven subfloor without breaking or cracking.
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 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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.
