1.1本分类涵盖了根据耐久性特征对墙面材料进行的分类，即根据其在使用中的可用性，认识到某些墙面材料主要是为了装饰效果而设计的，而其他墙面材料也旨在实现高可用性。 1.2以英寸-磅为单位的数值应视为标准值。括号中给出的度量值仅供参考。 1.3本分类中的易燃性测试应用于测量和描述材料、产品或组件在受控实验室条件下对热和火焰的响应特性，而不应用于描述或评估材料、产品或组件在实际火灾条件下的火灾危险或火灾风险。 然而，该测试结果可作为火灾风险评估的要素，该评估考虑了与特定最终用途火灾危险评估相关的所有因素 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和健康实践，并确定监管限制的适用性。

1.1 This classification covers the classification of wallcovering by durability characteristics, that is, according to its serviceability in use, recognizing that certain wallcovering is designed primarily for decorative effect, while other wallcovering is also designed to achieve a high degree of serviceability. 1.2 The values stated in inch-pound units are to be regarded as the standard. The metric values given in parentheses are provided for information only. 1.3 The flammability test in this classification should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment that takes into account all of the factors that are pertinent to an assessment of the fire hazard of a particular end use This standard does not purport to address all of the safety problems, 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.
