 【摘要】  

Resilient floor covering is made by fusing polymer materials under heat or pressure, or both, in various manufacturing and decorating processes. The polymer material may be compounded with plasticizers, stabilizers, fillers, and other ingredients for processibility and product performance characteristics. The formulation of the compound can be varied considerably depending on the desired performance characteristics and methods of processing. See Practice D 794 for additional significance and use information.

Heat stability, which is resistance to discoloration from heat, is a basic requirement for processing and functional use.

This test method provides a means of measuring the amount of color change in flooring products when subjected to elevated temperatures over a period of time (functional use of the flooring product).

This test method is not intended to be a means of predicting the amount of color change that occurs during processing (manufacture).

This test method specifies that a sample is subjected to 158x00B0;F x00B1; 2x00B0;F (70x00B0;C x00B1; 1x00B0;C) for 7 days, and the color difference is measured by a spectrophotometer and expressed as x0394;E* units.

Note 18212;It is the intent that this test method be used for testing heat stability performance properties to be referenced in resilient flooring specifications.

1.1 This test method covers a procedure for determining the resistance of resilient floor covering to color change from exposure to elevated temperature over a specified period of time.

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.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
