1.1 本指南提供了一个通用测试程序，用于验证工厂/制造环境中应用于金属、塑料、木材或复合基材的液体涂料的空气污染预防特性和基本特性。因此，它可以用于评估这些液体涂料，以验证其挥发性有机化合物（VOC）和有机有害空气污染物（HAP）含量以及基本性能。 1.2 本指南改编自美国环境保护局（EPA）使用的程序，该程序旨在对有可能减少空气排放的涂层的物理特性和性能进行第三方验证。 验证测试的数据可在EPA环境技术验证（ETV）计划网站的互联网上获得( http://www.epa.gov/etv/centers/center6.html )在“P2创新涂料和涂装设备试点” 1.3 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。 1.4 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。 1.5 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====== 3.1 本验证指南的主要目标是确定工厂应用液体涂料的“空气污染预防潜力”（VOC或HAP排放的可能减少）。 3.2 本指南的总体目标是验证液体涂层技术的上述污染预防特征和基本性能特征。使用本指南可以提高对更环保的产品加工技术的接受度，同时减少对大气的排放。本指南的具体目标是( 1. )量化液体涂料的VOC和HAP含量，并( 2. )验证这些涂层的基本质量和耐久性。 3.3 液体涂层验证的主要标准为: 3.3.1 确认涂料的使用将显著减少应用或固化期间的VOC和HAP含量或排放量（或两者兼有），或两者兼有。 3.3.2 确认涂层可为预期最终用途提供可接受的饰面（外观、硬度、柔韧性等）。 3.4 本指南的测试结果可为潜在用户提供最佳可用数据，以确定涂层是否在满足预期用途的表面质量要求的同时提供污染预防效益。本指南旨在为最终用户提供无偏见的技术数据，以帮助他们做出决策- 制作过程。 3.5 定量的空气污染预防潜力取决于多种因素；因此，液体涂层应按照涂层供应商的说明进行涂覆，由此产生的验证数据仅反映试验的特定条件。为了量化环境效益（空气污染预防潜力），将进行一项测试，以量化新液体涂料的VOC或HAP排放量，并将其与目标行业通常使用的现有涂料的数据进行比较。

1.1 This guide provides a generic testing procedure to verify the air pollution-prevention characteristics and basic properties of liquid coatings applied to metal, plastic, wood, or composite substrates in a factory/manufacturing environment. Thus it may be used to evaluate these liquid coatings to verify their volatile organic compound (VOC) and organic hazardous air pollutant (HAP) content as well as basic performance properties. 1.2 This guide is adapted from a procedure used by the US Environmental Protection Agency (EPA) to establish third party verification of the physical properties and performance of coatings that have potential to reduce air emissions. The data from the verification testing is available on the internet at the EPA’s Environmental Technology Verification (ETV) Program website ( http://www.epa.gov/etv/centers/center6.html ) under the “P2 Innovative Coatings and Coating Equipment Pilot.” 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 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. 1.5 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 ====== 3.1 The primary objective of this verification guide is to determine the “air pollution-prevention potential” (possible reduction in VOC or HAP emissions) of factory-applied liquid coatings. 3.2 The overall objective of this guide is to verify the above pollution-prevention characteristics and basic performance characteristics of liquid coating technologies. Use of this guide can increase acceptance of more environmentally friendly technologies for product finishing with an accompanying reduction in emissions to the atmosphere. The specific objectives of this guide are to ( 1 ) quantify the VOC and HAP content of liquid coatings and ( 2 ) verify the basic quality and durability performance of these coatings. 3.3 The primary criteria for verification of liquid coatings will be: 3.3.1 Confirm that use of the coating will significantly reduce VOC and HAP content or emissions (or both) during application or cure, or both. 3.3.2 Confirm that the coating can provide an acceptable finish (appearance, hardness, flexibility, etc.) for the intended end use. 3.4 The test results from this guide can provide to potential users the best data available to determine whether the coating will provide a pollution-prevention benefit while meeting the finish quality requirements for its intended use. This guide intends to supply end users with unbiased technical data to assist them in this decision-making process. 3.5 The quantitative air pollution-prevention potential depends on a multitude of factors; therefore, the liquid coatings are to be applied in accordance with the coating vendor’s instructions and the resulting verification data reflect only the specific conditions of the test. To quantify the environmental benefit (air pollution-prevention potential), a test to quantify the VOC or HAP emissions from the new liquid coatings will be conducted and compared to data for existing coatings typically used in the target industry.
