1.1 本试验方法提供了一种程序，用于测定弹性地板覆盖物在暴露于各种化学试剂时对表面劣化的耐受性。本试验方法既不是染色试验，也不是判断样品暴露于化学试剂后表面和外观恢复的方法。 1.2 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.3 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。 第节提供了具体的危险信息 6. 本试验方法。 1.4 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 弹性地板产品的设计和配方能够很好地抵抗典型使用中遇到的大多数常见化学品。高性能耐磨层也可用于增强清洁性和耐化学性。住宅和商业环境中使用的弹性地板可能因意外泄漏而受到各种化学品的影响，或作为用于卫生目的的成分。性能取决于地板配方和地板上使用的维护产品。本试验方法提供了一种估算弹性地板覆盖物在暴露于化学试剂时发生变化的相对敏感性的方法。

1.1 This test method provides a procedure for determining the resistance of resilient floor covering to surface deterioration when exposed to various chemical reagents. This test method is not intended as a staining test nor as a method to judge surface and appearance restoration of the sample after exposure to the chemical reagent. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard information is provided in Section 6 of this test method. 1.4 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 flooring products are designed and formulated to have good resistance to most common chemicals encountered in typical use. High performance wear layers can also be used to enhance cleanability and chemical resistance. Resilient flooring used in residential and commercial environments may be subjected to a variety of chemicals through accidental spillage or as ingredients used for hygienic purposes. Performance is dependent upon the flooring formulation and that of the maintenance products used on the flooring. This test method provides a means of estimating the relative susceptibility of resilient floor covering to change when exposed to chemical reagents.
