Standard Test Method for Measuring Light Stability of Resilient Flooring by Color Change 通过颜色变化测量弹性地板的光稳定性的标准测试方法
发布日期: 2021-04-01
1.1 本试验方法涵盖了一个程序,用于确定弹性地板覆盖物在指定时间段内暴露在光照下的耐变色性。 1.2 本标准并非旨在解决与其使用相关的所有安全问题(如有)。本标准的用户有责任在使用前制定适当的安全、健康和环境实践,并确定监管限制的适用性。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒(TBT)委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 弹性地板覆盖物是通过在各种制造和装饰过程中,在高温或压力下,或两者兼而有之的情况下,将聚合物材料熔融而成。聚合物材料可与增塑剂、稳定剂、填料和其他成分复合,以获得加工性能和产品性能特征。根据所需的性能特征和加工方法,化合物的配方可以有很大的变化。 4.2 抗光变色的光稳定性是功能性使用的基本要求。 4.3 本试验方法提供了一种测量地板产品在一段时间内受到加速光照射时颜色变化量的方法(地板产品的功能性使用)。 4.4 本试验方法规定,在加速光照射前后,用分光光度计测量样品,并用ΔE*单位表示。 注2: 本试验方法用于测试弹性地板规范中参考的光稳定性性能。
1.1 This test method covers a procedure for determining the resistance of resilient floor covering to color change from exposure to light 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.3 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. ====== Significance And Use ====== 4.1 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 processability and product performance characteristics. The formulation of the compound can be varied considerably depending on the desired performance characteristics and methods of processing. 4.2 Light stability, which is resistance to discoloration from light, is a basic requirement for functional use. 4.3 This test method provides a means of measuring the amount of color change in flooring products when subjected to accelerated light exposure over a period of time (functional use of the flooring product). 4.4 This test method specifies that a sample is measured by a spectrophotometer and expressed in ΔE* units before and after accelerated light exposure. Note 2: It is the intent that this test method be used for testing light stability performance properties to be referenced in resilient flooring specifications.
