1.1 该分类涵盖了按使用特征对墙面覆盖物的分类，即根据其在使用中的可用性，认识到某些墙面覆盖物主要是为了装饰效果而设计的，而其他墙面覆盖物也旨在实现高可用性。 1.1.1 该分类适用于任何墙面覆盖物，但某些章节特别适用于乙烯基涂层墙面覆盖材料。 1.1.2 当该分类涉及墙面覆盖物时，也指相同类型的天花板覆盖物。 1.1.3 该分类不适用于拟用于外墙的墙面覆盖物。 1.1.4 该分类不适用于刚性面板产品，无论其是否包括柔性衬里或单板。 1.2 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，每个系统应相互独立使用。将两个系统的值结合起来可能会导致不符合标准。 1.3 本标准用于测量和描述材料、产品或组件在受控条件下的加热和燃烧性能，但其本身并不包括在实际火灾条件下对材料、产品或组件进行火灾危险或火灾风险评估所需的所有因素。 1.4 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。 1.5 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 这种分类提供了标准，根据这些标准，可以为特定的住宅和商业装饰应用选择具有适当使用特性的墙面覆盖物。

1.1 This classification covers the classification of wall coverings by use characteristics, that is, according to their serviceability in use, recognizing that certain wall coverings are designed primarily for decorative effect, while other wall coverings are also designed to achieve a high degree of serviceability. 1.1.1 This classification applies to any wall covering but some sections apply specifically to vinyl-coated wall covering materials. 1.1.2 Whenever this classification refers to wall coverings, it is intended also to refer to ceiling coverings of the same type. 1.1.3 This classification does not apply to wall coverings intended to be applied to exterior walls. 1.1.4 This classification does not apply to rigid panel products, irrespective of whether or not they include a flexible lining or veneer. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems has the potential to result in non-conformance with the standard. 1.3 This standard is used to measure and describe the properties of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions. 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. ====== Significance And Use ====== 4.1 This classification provides criteria by which wall coverings of appropriate use characteristics can be chosen for particular residential and commercial decorating applications.
