Standard Test Method for Resistance to Impact for Resilient Floor Tile

SIGNIFICANCE AND USE
Resilient floor tile is subjected to impacts from objects that may be inadvertently dropped on to surfaces. It is not possible to know all of the factors related to the dropped objects (shape, weight, height of drop) or the condition of the environment in which the tile is located (types of subfloor, degree of adhesion to subfloor, temperature). Therefore, this test method can only provide a relative measure of resistance of resilient floor tile to impact.
SCOPE
1.1 This test method is intended for use in determining the resistance to impact of resilient non-textile floor coverings such as vinyl composition and asphalt tile.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values 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 limitaions prior to use.
