Standard Test Method for Quality of Cut (Joint Tightness) of Resilient Floor Tile
SCOPE
1.1 This test method covers a means of measuring and evaluating the quality of cut (joint tightness) of 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 problems, 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.
