1.1 本试验方法涵盖一个小规模实验室程序，通过确定喷雾模式和气溶胶沉积速率来确定气溶胶产品的吸入潜力。 1.2 开发本试验方法是为了解决识别哪些气溶胶产品可能存在吸入风险的需要，以便适当使用特殊标签和/或儿童防护包装。基于该方法的研究可能有助于制定识别此类气溶胶产品的实践。 1.3 虽然该方法可能对测试非加压气溶胶产品有用，但其开发仅限于测试加压气溶胶。 1.4 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1. 5. 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。 1.6 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====== 4.1 本试验方法提供了一种方法，用于测量如果分配的气溶胶进入口腔，气溶胶产品是否可能存在吸入风险。 4.2 吸入气溶胶的风险程度取决于喷雾模式和气溶胶沉积速率。 2. 4.3 本试验方法将用于确定气溶胶产品是否需要儿童防护包装。

1.1 This test method covers a small-scale laboratory procedure to determine the aspiration potential of aerosol products by determining spray pattern and aerosol deposition rates. 1.2 This test method has been developed to address a need to identify which aerosol products may present an aspiration risk such that special labeling and/or child-resistant packaging would be appropriate. Studies based on this method may allow the development of a practice to identify such aerosol products. 1.3 Although this method may be useful for testing non-pressurized aerosol products, its development has been limited to testing pressurized aerosols. 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 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. 1.6 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 ====== 4.1 This test method provides a means of measuring whether or not an aerosol product may present an aspiration risk if a dispensed aerosol gets into one’s mouth. 4.2 The degree of risk for aspiration of an aerosol depends both on spray pattern as well as aerosol deposition rate. 2 4.3 This test method will be used to determine the need for child-resistant packaging of aerosol products.
