1.1 本指南提供了一种用于记录空气中颗粒物渗透测试的信息和性能数据的格式。 1.2 记录的数据和信息分为五类，定义了每个测试的重要方面: 1.2.1、 测试材料的说明， 1.2.2 挑战粒子， 1.2.3 试验方法， 1.2.4 测试结果，以及 1.2.5 数据来源。 1.3 遵守标准测试方法中概述的程序有助于本指南的使用。 1.4 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测量单位。 1.5 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====== 2.1 本指南旨在鼓励对空气中颗粒物渗透测试及其结果进行彻底和一致的记录。 2.2 统一的信息和性能数据增加了通过直接比较一种材料与另一种材料来选择合适的颗粒防护服的可能性。 2.3 测试信息和数据的标准格式也鼓励计算机存储测试结果，以便于检索、比较和关联。

1.1 This guide provides a format for documenting information and performance data for an airborne particle penetration test. 1.2 Documented data and information are grouped into five categories that define important aspects of each test: 1.2.1 Description of material tested, 1.2.2 Challenge particles, 1.2.3 Test method, 1.2.4 Test results, and 1.2.5 Source of the data. 1.3 Use of this guide is facilitated by adherence to procedures outlined in a standard test method. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurements are included in this standard. 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 ====== 2.1 This guide is intended to encourage thorough and consistent documentation of airborne particle penetration testing and its results. 2.2 Uniform information and performance data increase the likelihood of selecting proper particle protective clothing by direct comparison of one material with another. 2.3 A standard format for test information and data also encourages computer storage of test results for easy retrieval, comparison, and correlations.
