1.1 本规程旨在确定在办公和住宅建筑中常见的环境和产品使用条件下，材料和产品（建筑材料、材料系统、家具、消费品等）以及设备（打印机、复印机、空气滤清器等）的挥发性有机化合物（VOC）排放量。 1.2 本规程用于识别排放的挥发性有机化合物，并确定其在一段时间内的排放率。 1.3 本规程描述了VOC排放测试全尺寸室的设计、施工、性能评估和使用。 1.4 虽然本规程仅限于VOC排放的测量，但许多一般原则和程序（例如评估燃烧室系统一般性能的方法）也可能适用于其他化学排放的测定（例如，臭氧、二氧化氮）。气溶胶和颗粒物排放的测定超出了本文件的范围。 1.5 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。 1.6 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。 1.7 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 材料/产品排放的挥发性有机化合物影响建筑物的室内空气质量。 为了确定这些排放物对室内空气品质的影响，有必要了解其随时间的排放率。本规程提供了使用全尺寸环境室测试大型材料和全尺寸材料系统/组件的指南。 5.2 虽然本规程是为测量挥发性有机化合物排放量而制定的，但本规程中提出的燃烧室设施和评估方法也适用于各种目的，包括:( 1. )测试应用过程中的排放物（例如涂漆）或其他相关来源；( 2. )开发缩放方法（例如，从小室结果到完整的- 规模场景）；( 3. )研究源和汇之间的相互作用，验证作为室内空气品质预测基础的源/汇模型；( 4. )测试源排放物与空气中其他化合物之间的相互作用（例如，NO x ，臭氧 x ); 和( 5. )评估旨在去除室内空气中污染物的空气净化装置的性能。

1.1 This practice is intended for determining volatile organic compound (VOC) emissions from materials and products (building materials, material systems, furniture, consumer products, etc.) and equipment (printers, photocopiers, air cleaners, etc.) under environmental and product usage conditions that are typical of those found in office and residential buildings. 1.2 This practice is for identifying VOCs emitted and determining their emission rates over a period of time. 1.3 This practice describes the design, construction, performance evaluation, and use of full-scale chambers for VOC emission testing. 1.4 While this practice is limited to the measurement of VOC emissions, many of the general principles and procedures (such as methods for evaluating the general performance of the chamber system) may also be useful for the determination of other chemical emissions (for example, ozone, nitrogen dioxide). Determination of aerosol and particle emissions is beyond the scope of this document. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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. 1.7 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 VOCs emitted from materials/products affect indoor air quality (IAQ) in buildings. To determine the impact of these emissions on IAQ, it is necessary to know their emission rates over time. This practice provides guidelines for using a full-scale environmental chamber for testing large materials and full-scale material systems/assemblies. 5.2 While this practice is developed for measuring VOC emissions, the chamber facilities and methods of evaluation presented in this practice are also useful for a variety of purposes including: ( 1 ) testing the emissions during the application process (for example, painting), or other related sources; ( 2 ) developing scaleup methods (for example, from small chamber results to a full-scale scenario); ( 3 ) studying the interaction between sources and sinks, and validating source/sink models which are the basis for IAQ prediction; ( 4 ) testing interactions between source emissions and other compounds in the air (for example, NO x , ozone, SO x ); and ( 5 ) evaluating the performance of air cleaning devices intended to remove contaminants from indoor air.
