1.1 本规程描述了使用小型环境室测试设施测试醇酸漆、乳胶漆、底漆和其他建筑涂料样品中挥发性有机化合物（VOCs）、甲醛和其他羰基化合物排放的程序。 1.2 本规程描述了室内试验设施、小型试验室、清洁空气供应系统、环境控制、环境监测和数据采集系统以及室内空气采样系统的要求。 1.3 本规程描述了记录油漆和涂层样品的程序，以及处理和储存这些样品的程序，包括将样品分成更小的容器进行储存和后续测试。 1.4 本规程确定了用于制备油漆和涂料试样的适当基质，以及用于制备使用基质的程序。 1.5 本规程提供了制备油漆和涂层样品试样的详细程序。 1.6 本规程通常描述了室内试验程序和室内空气取样程序。这些程序的细节取决于测试的目标。 1.7 本规程不推荐VOC、甲醛和其他羰基化合物采样和分析的具体方法。适当的方法取决于测试的目标。 1.8 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.9 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。 1.10 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====== 5.1 乳胶漆、醇酸漆和底漆用作被占用建筑物的墙壁、木质装饰和家具的涂料。油漆可用于较大的表面区域，并可在建筑物的使用寿命内重复使用。喷涂到表面后，油漆中会释放出挥发性有机物。 5.2 许多其他类型的建筑涂料可在建筑物的室内大量使用。特别是，许多不同类型的涂料用于地板，包括木地板污渍和饰面以及混凝土密封剂、硬化剂和污渍。两种组件饰面通常在现场混合，并应用于地板和其他表面，以创建成品表面。 5.3 需要标准化的程序来测量油漆和涂料样品的挥发性有机化合物排放量，这些程序可由不同的实验室复制，并可用于评估拟在占用空间内室内使用的油漆和涂料的挥发性有机化合物排放量的可接受性。本规程描述了可纳入测试方法的标准化程序，用于评估固化油漆和涂料对室内空气质量的影响。估计使用此类产品的工人的挥发性有机化合物暴露量需要不同的程序。

1.1 This practice describes procedures for testing the emissions of volatile organic compounds (VOCs), formaldehyde, and other carbonyl compounds, from alkyd paint, latex paint, primer, and other architectural coating samples using a small-scale environmental chamber test facility. 1.2 This practice describes the requirements for the chamber test facility, the small-scale test chamber, the clean air supply system, the environmental controls, the environmental monitoring and data acquisition system, and the chamber air sampling system. 1.3 This practice describes procedures for documenting the paint and coating samples and for the handling and storage of these samples including splitting of samples into smaller containers for storage and subsequent testing. 1.4 This practice identifies appropriate substrates to be used for the preparation of test specimens of paints and coatings, as well as procedures for preparing substrates for use. 1.5 This practice provides detailed procedures for preparing test specimens of paint and coating samples. 1.6 This practice generally describes chamber test procedures and chamber air sampling procedures. The details of these procedures are dependent upon the objectives of the test. 1.7 This practice does not recommend specific methods for sampling and analysis of VOCs, formaldehyde, and other carbonyl compounds. The appropriate methods are dependent upon the objectives of the test. 1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.9 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. 1.10 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 ====== 5.1 Latex paints, alkyd paints, and primers are used as coatings for walls, wooden trim, and furnishings in occupied buildings. Paint may be applied to large surface areas and may be applied repeatedly during the lifetime of a building. VOCs are emitted from paint after application to surfaces. 5.2 Many other types of architectural coatings may be used in large quantities indoors in buildings. In particular, many different types of coatings are used for floors including wood floor stains and finishes and concrete sealers, hardeners, and stains. Two component finishes are often mixed on site and are applied to floors and other surfaces to create a finished surface. 5.3 There is a need for standardized procedures for measuring the emissions of VOCs from paint and coating samples that can be reproduced by different laboratories and that can used for the assessment of the acceptability of VOC emissions from paints and coatings that are intended for use indoors in occupied spaces. This practice describes standardized procedures that can be incorporated into test methods used for the purpose of estimating the impacts of cured paints and coatings on indoor air quality. Different procedures are required for the estimation of VOC exposures to workers applying such products.
