1.1 本规程描述了一种微型室设备和相关程序，用于快速筛选材料和产品的气相挥发性有机化合物（VOC）排放，包括甲醛和其他羰基化合物。它旨在补充而不是取代测量化学排放的参考方法，例如小规模室内试验（指南 D5116 )和发射电池测试（实践 D7143 )。 1.2 这种做法适用于实验室内外、制造现场和有电源的现场。 1.3 可在微米级腔室设备中测试的兼容材料/产品类型包括刚性材料、干燥或固化的油漆和涂层、可压缩产品以及小的、不规则形状的部件，如聚合物珠。 1.4 本规程描述了将从微型试验室获得的排放结果与VOC排放参考方法获得的结果进行关联的试验（例如，指南 D5116 ，试验方法 D6007 实践 D7143 以及ISO 16000-9和ISO 16000-10）。 1.5 微型腔室设备在适度升高的温度下操作，30 °C至60 °C，以消除冷却的需要，减少测试时间，提高排放率，增强常规排放筛查的分析信号，并促进半成品的筛查- 挥发性VOC（SVOC）排放，例如一些邻苯二甲酸酯和其他增塑剂的排放。 1.6 气体样本采集和化学分析取决于目标挥发性有机物的性质，超出了本规范的范围。但是，试验方法中描述的程序 D7339 实践 D6196 和ISO 16000-6中的挥发性有机物分析和试验方法 D5197 以及用于分析甲醛和其他羰基化合物的ISO 16000-3适用于该实践。 1.7 以国际单位制表示的数值应视为标准。 本标准中不包括其他计量单位。 1.8 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.9 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 6.1 越来越多的制造商被要求或被要求证明其产品在正常使用条件下的气相排放符合各种自愿或监管验收标准。该过程通常要求制造商使用指定的参考测试方法（例如，测试方法 D6007 、ISO 16000-9和ISO 16000-10）。为了确保持续合规性，制造商可以选择或被要求在生产层面实施筛查测试。 6.2 测试产品化学排放的参考方法非常严格，对于生产环境中的常规排放筛查来说，通常过于耗时和不切实际。 6.3 微型室的独特之处在于，它们的小尺寸和在适度升高的温度下的操作有助于快速平衡和缩短测试时间。只要能够证明与参考测试结果的充分可重复相关性，就可以建立适当的控制水平，并且可以使用微规模试验室数据来监测产品制造是否可能符合参考验收标准。 结果的周转时间增加，可以更及时地调整参数，以保持气相化学排放方面的一致生产。 6.4 这种做法也可用于监测制造过程中原材料的质量。 6.5 高温的使用还促进了半挥发性挥发性有机物（SVOC）排放的筛选测试，如一些邻苯二甲酸酯和其他增塑剂。

1.1 This practice describes a micro-scale chamber apparatus and associated procedures for rapidly screening materials and products for their vapor-phase emissions of volatile organic compounds (VOCs) including formaldehyde and other carbonyl compounds. It is intended to complement, not replace reference methods for measuring chemical emissions for example, small-scale chamber tests (Guide D5116 ) and emission cell tests (Practice D7143 ). 1.2 This practice is suitable for use in and outside of laboratories, in manufacturing sites and in field locations with access to electrical power. 1.3 Compatible material/product types that may be tested in the micro-scale chamber apparatus include rigid materials, dried or cured paints and coatings, compressible products, and small, irregularly-shaped components such as polymer beads. 1.4 This practice describes tests to correlate emission results obtained from the micro-scale chamber with results obtained from VOC emission reference methods (for example, Guide D5116 , Test Method D6007 , Practice D7143 , and ISO 16000-9 and ISO 16000-10). 1.5 The micro-scale chamber apparatus operates at moderately elevated temperatures, 30 °C to 60 °C, to eliminate the need for cooling, to reduce test times, boost emission rates, and enhance analytical signals for routine emission screening, and to facilitate screening of semi-volatile VOC (SVOC) emissions such as emissions of some phthalate esters and other plasticizers. 1.6 Gas sample collection and chemical analysis are dependent upon the nature of the VOCs targeted and are beyond the scope of this practice. However, the procedures described in Test Method D7339 , Practice D6196 and ISO 16000-6 for analysis of VOCs and in Test Method D5197 and ISO 16000-3 for analysis of formaldehyde and other carbonyl compounds are applicable to this practice. 1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.8 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. 1.9 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 ====== 6.1 Manufacturers increasingly are being asked or required to demonstrate that vapor-phase emissions of chemicals of concern from their products under normal use conditions comply with various voluntary or regulatory acceptance criteria. This process typically requires manufacturers to have their products periodically tested for VOC emissions by independent laboratories using designated reference test methods (for example, Test Method D6007 , ISO 16000-9, and ISO 16000-10). To ensure continuing compliance, manufacturers may opt to, or be required to, implement screening tests at the production level. 6.2 Reference methods for testing chemical emissions from products are rigorous and typically are too time-consuming and impractical for routine emission screening in a production environment. 6.3 Micro-scale chambers are unique in that their small size and operation at moderately elevated temperatures facilitate rapid equilibration and shortened testing times. Provided a sufficiently repeatable correlation with reference test results can be demonstrated, appropriate control levels can be established and micro-scale chamber data can be used to monitor product manufacturing for likely compliance with reference acceptance criteria. Enhanced turnaround time for results allows for more timely adjustment of parameters to maintain consistent production with respect to vapor-phase chemical emissions. 6.4 This practice can also be used to monitor the quality of raw materials for manufacturing processes. 6.5 The use of elevated temperatures additionally facilitates screening tests for emissions of semi-volatile VOCs (SVOCs) such as some phthalate esters and other plasticizers.
