4.1 The final appearance of an installed tile floor depends upon several factors. These include but are not limited to size and squareness of the tile, the quality of joint cut, the quality and preparation of the subfloor and the skill of the installer. Long term appearance of the installed floor is also dependent on but not limited to the ability of the tile to resist shrinkage due to internal stress relief. This test method is used to measure the ability of floor tile to retain its original dimensions following exposure to heat simulating a long service life at reasonable and expected temperatures.

1.1 This test method covers the determination of the change in linear dimensions of resilient floor tile after exposure to heat.

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.
