1.1本规范描述了不受静水压力影响的建筑甲板防水用低温液体弹性膜的要求性能和测试方法。本规范仅适用于具有完整磨损表面的膜系统。本规范不包括防滑性或阻燃性的具体要求，尽管两者在特定用途中可能都很重要。 1.2本规范中描述的膜系统类型用于行人和车辆交通以及高磨损应用。膜可以是单组分或多组分的，并且可以由一层或多层涂层（例如底漆、面漆等）组成。涂层可在一个或多个应用中构建至所需厚度。一层（底层）提供主要防水功能，通常包括膜中的大量有机材料。面漆的功能是耐磨和耐候。 骨料可作为膜系统的一个组成部分，作为一层的全部或部分，以增加耐磨性和防滑性。 1.3对本标准具有管辖权的委员会不知道其他组织发布的任何可比标准。 1.4本规范中的试验方法要求最小0.5-mm（0.020-in.）底漆干膜厚度。特定应用和面漆中骨料的使用所需的实际厚度应由薄膜制造商确定。 1.5以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.6以下安全隐患警告仅适用于本规范第5节试验方法部分: 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 specification describes the required properties and test methods for a cold liquid-applied elastomeric membrane for waterproofing building decks not subject to hydrostatic pressure. The specification applies only to a membrane system that has an integral wearing surface. This specification does not include specific requirements for skid resistance or fire retardance, although both may be important in specific uses. 1.2 The type of membrane system described in this specification is used for pedestrian and vehicular traffic and in high-abrasion applications. The membrane may be single- or multi-component, and may consist of one or more coats (for example base coat, top coat, etc.). The coat(s) may be built to the desired thickness in one or more applications. One coat (base coat) provides the primary waterproofing function and normally comprises the major amount of organic material in the membrane. The function of the top coat(s) is to resist wear and weather. Aggregate may be used as a component of the membrane system, as all or part of a course, to increase wear and skid resistance. 1.3 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations. 1.4 Test methods in this specification require a minimum 0.5-mm (0.020-in.) base coat dry film thickness. Actual thickness required for a particular application and the use of aggregate in topcoats shall be established by the membrane manufacturer. 1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only. 1.6The following safety hazards caveat pertains only to the test method portion, Section 5, of this specification: 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.
