(Test Method)Standard Test Method for Dimensional Stability of Fabrics to Changes in Humidity and Temperature
Standard Test Method for Dimensional Stability of Fabrics to Changes in Humidity and Temperature
SIGNIFICANCE AND USE
5.1 The measured dimensional stability of a fabric determines whether a fabric has the potential to retain its original shape and remain stable, indicating it will not bubble or sag over time, when applied over a substrate, and its suitability for a specified use.
5.2 This test method is recommended for acceptance testing of commercial shipments however, caution is advised since information about between laboratory precision is incomplete. Comparative tests as directed in 5.2.1 are advisable.
5.2.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative test should be performed to determine if there is a statistical bias between them, using competent statistical assistance. At a minimum, use the samples for such a comparative test that are as homogeneous as possible, drawn from the same lot of material as the samples that resulted in disparate results during initial testing and randomly assigned in equal numbers to each laboratory. The test results from the laboratories involved should be compared using a statistical test for unpaired data, a probability level chosen prior to the testing series. If bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias.
5.3 This test method is used in industry to determine if a fabric grows, grows and then shrinks, shrinks and then grows, or remains the same when subjected to a specified range of humidity and temperature conditions.
SCOPE
1.1 This test method covers the determination of the dimensional stability of fabrics that are intended for use on panel and screen systems to cycled changes in humidity and temperature.
1.1.1 Panel and screen systems include acoustic panels, free standing screens, office partitions, and furniture systems.
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are approximate inch-pound unit equivalents and 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 limitations prior to use.
