(Test Method)Standard Test Method for Quality of Cut (Joint Tightness) of Resilient Floor Tile
Standard Test Method for Quality of Cut (Joint Tightness) of Resilient Floor Tile
SIGNIFICANCE AND USE
Installations of resilient floor tile require tight joints if satisfactory appearance is to result. The quality of cut of resilient tile is determined by this test method.
SCOPE
1.1 This test method covers a means of measuring and evaluating the quality of cut (joint tightness) of square or rectangular resilient floor tile. Characteristics that detract from a monolithic (seamless) appearance, such as burred, chipped, nicked, or beveled edges, or bow cut or rounded corners, are measured or observed, or both.
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.
