1.1 本规程描述了新喷涂聚氨酯泡沫（SPF）绝缘产品样品的制备、喷涂、包装和运输的标准化程序，以测试其挥发性有机化合物（VOCs）和半挥发性有机化合物（SVOCs）的排放。这些程序适用于闭孔和开孔SPF绝缘产品。潜在的化学排放物包括发泡剂、溶剂、醛、胺催化剂、二异氰酸酯和阻燃剂。 1.2 通常，SPF绝缘样品在一个位置制备，例如化学品制造设施或现场产品安装现场。新制备的样品保存在密封袋中，放置在二次容器中，然后运送到实验室进行测试。 1.3 SPF绝缘产品的喷涂只能由经过培训的人员在受控条件下使用专业喷涂设备进行。喷涂设备和喷涂程序的细节基于行业惯例，不在本惯例范围内。 1.4 本规程还描述了从开孔和闭孔SPF绝缘产品样品中制备试样的实验室程序。这些样本按照指南在小型试验室中进行试验 D5116 在试验方法中所述的微型室中 D8142 . 1.5 VOC和SVOC排放测试、气体样本采集和化学分析的程序不在本规程范围内。 此类程序需要解决一些SVOC的排放潜力，例如胺催化剂、阻燃剂和异氰酸酯，以粘附在室壁上。 1.6 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。 1.7 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。 1.8 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 SPF绝缘材料制造商可能需要测试其产品的挥发性和半挥发性有机化合物的气相排放，以符合自愿标准、采购规范或其他要求。 5.2 由于SPF绝缘是在喷涂过程中结合双组分混合物时通过化学反应形成的，因此需要专门的设备和程序来重复创建适合排放测试的代表性样品。 5.3 必须仔细遵守SPF绝缘产品制造商的规范和说明，并记录有关喷涂过程的详细信息（见 7.3 ). 需要关于搬运和运输的其他预防措施，以确保通过实际手段尽可能保持样品的化学完整性（见 7.5 ). 5.4 实验室必须以一致的方式从SPF绝缘样品中制备代表性试样，以便能够再现发射试验，并在不同样品的试验数据之间进行可靠比较。

1.1 This practice describes standardized procedures for the preparation, spraying, packaging, and shipping of fresh spray polyurethane foam (SPF) insulation product samples to be tested for their emissions of volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs). These procedures are applicable to both closed-cell and open-cell SPF insulation products. Potential chemical emissions of interest include blowing agents, solvents, aldehydes, amine catalysts, diisocyanates, and flame retardants. 1.2 Typically, SPF insulation samples are prepared at one location, such as a chemical manufacturing facility or a field product installation site. The newly prepared samples are preserved in a sealed bag, placed in a secondary container, and then shipped to a laboratory for testing. 1.3 The spraying of SPF insulation products is only to be performed by trained individuals using professional spraying equipment under controlled conditions. The details of the spraying equipment and spraying procedures are based on industry practice and are outside of the scope of this practice. 1.4 This practice also describes procedures for the laboratory preparation of test specimens from open-cell and closed-cell SPF insulation product samples. These specimens are prepared for testing in small-scale chambers following Guide D5116 and in micro-scale chambers that are described in Test Method D8142 . 1.5 Procedures for VOC and SVOC emission testing, gas sample collection and chemical analysis are outside of the scope of this practice. Such procedures will need to address the potential for emissions of some SVOCs, for example, amine catalysts, flame retardant and isocyanates, to adhere to the chamber walls. 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 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. 1.8 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 Manufacturers of SPF insulation may need to test their products for vapor-phase emissions of volatile and semi-volatile organic compounds in order to comply with voluntary standards, purchase specifications, or other requirements. 5.2 Since SPF insulation is formed by chemical reaction when combining a two-component mixture during spraying, specialized equipment and procedures are needed to reproducibly create representative samples suitable for emission testing. 5.3 SPF insulation product manufacturer’s specifications and instructions must be followed carefully and detailed information regarding the spraying process must be recorded (see 7.3 ). Other precautions regarding handling and shipping are needed to ensure that the chemical integrity of the samples is preserved to the extent possible by practical means (see 7.5 ). 5.4 Laboratories must prepare representative test specimens from samples of SPF insulation in a consistent manner so that emission tests can be reproduced and reliable comparisons can be made between test data for different samples.
