Standard Practice for Preparation of Textiles Prior to Ultraviolet (UV) Transmission Testing
SIGNIFICANCE AND USE
5.1 The significance of this practice is that a textile intended to be labeled as UV-protective, which will ultimately be submitted for UV transmittance testing, will be in a state that simulates its condition at the end of two years of normal seasonal use. UV resistance of a textile is dynamic and will constantly change. The simulated conditions are to be regarded as only estimates of the changes that will occur to the textile in two years of normal seasonal use.
5.2 To learn the quantitative measure of UV transmission or blocking, reference AATCC TM183.
5.3 To label textiles as UV-protective, reference Specification D6603.
SCOPE
1.1 This practice covers standardized exposures to laundering, simulated sunlight, and chlorinated pool water to simulate two years of seasonal exposure for apparel textiles labeled as ultraviolet (UV)-protective.
1.2 This practice is used in conjunction with AATCC TM183 and Specification D6603 as they relate to testing and labeling of UV-protective textiles after two years of simulated seasonal use.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
