1.1 本指南旨在提供一种标准化方法和一组基本说明，用于对包装设计进行内部和静水压测试。 1.2 本指南提供的信息有助于澄清联合国（UN）认证过程中使用的各种术语，这些术语可能有助于确定适用的测试。 1.3 本指南提供了在进行压力测试时应记录的建议最低信息。 1.4 本指南提供了用于进行压力测试的推荐设备和配件的信息。 1.5 本指南基于49 CFR、§173.27和§178.605中包含的当前信息。 1.6 当测试用于危险品（危险品）的包装设计时，本指南的用户应根据49 CFR§172.700和其他适用的危险品法规（如ICAO技术说明、IMDG规范）以及承运人规则（如IATA危险品法规）进行培训。 1.7 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. 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。 1.9 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 危险品（危险品）法规要求在授权使用前对包装设计进行性能测试。法规不包括进行性能测试的标准化程序，因此，可能会导致方法不统一以及测试设施之间的测试结果存在差异。 4.2 本指南旨在为正在进行联合国认证测试的包装或满足压力能力要求的包装进行内部压力测试提供指导并建立一套通用做法。 有关联合国认证要求的更多信息，请参阅指南 D4919 .

1.1 This guide is intended to provide a standardized method and a set of basic instructions for performing internal and hydrostatic pressure testing on packaging designs. 1.2 This guide provides information to help clarify various terms used as part of the United Nations (UN) certification process that may assist in determining the applicable test. 1.3 This guide provides the suggested minimum information that should be documented when conducting pressure testing. 1.4 This guide provides information for recommended equipment and fittings for conducting pressure tests. 1.5 This guide is based on the current information contained in 49 CFR, §173.27 and §178.605. 1.6 When testing packaging designs intended for hazardous materials (dangerous goods), the user of this guide shall be trained in accordance with 49 CFR §172.700 and other applicable hazardous materials regulations such as the ICAO Technical Instructions, IMDG Code, and carrier rules such as the IATA Dangerous Goods Regulations. 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 ====== 4.1 Dangerous goods (hazardous materials) regulations require performance tests to be conducted on packaging designs before being authorized for use. The regulations do not include standardized procedures for conducting performance tests and, because of this, may result in a non-uniform approach and differences in test results between testing facilities. 4.2 The purpose of this guide is to provide guidance and to establish a set of common practices for conducting internal pressure tests on packagings under going UN certification testing or packagings required to meet pressure capability requirements.
