1.1本指南的主要重点是确定联合国（UN）包装认证所需的关键信息，以确保所选包装的认证达到其预期用途的适当水平。本文件还提供了美国运输部第49篇《联邦法规》（CFR）相关章节的定位指南。必要时咨询监管专家。 1.2本指南旨在根据联合国关于危险货物运输的建议，协助确定根据美国运输部第49篇《联邦法规》性能导向包装标准认证包装设计所需的适当性能测试。 1.3本指南涵盖了净质量不超过400 kg（880 lb）或容量不超过450 L（119 gal）的危险品包装的运输测试，传染物质、放射性物质、气瓶和其他气体容器的包装除外。 1.4本指南不取代危险品包装的国内或国际法规要求，但强烈建议与这些法规一起使用。 1.5本指南的用户必须按照172要求的美国运输部第49篇《联邦法规》（49 CFR）进行培训。 700，并应熟悉其他适用的危险品法规，例如:；国际民用航空组织（ICAO）《危险品航空安全运输技术说明》、国际海上危险品规则（IMDG规则）和承运人规则，如国际航空运输协会（IATA）《危险品条例》。 1.6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。 1.7 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和健康实践，并确定监管要求的适用性。 ====意义和用途====== 联合国性能测试基于拟包装危险品的危害程度。 危险物质和物品被指定为3.8.1中定义的特定包装类别，可参考49 CFR 172确定。 101危险品表。 只有根据3.8.2中定义的联合国性能标准成功测试的包装设计才能标记联合国标志。除非相关主管部门另有授权，否则不得使用没有适当联合国标志的包装运输危险品。 根据联合国性能标准成功测试的包装可能承受也可能无法承受北美分销环境。为了进一步评估包装的适用性，强烈建议进行实施规程D 4169中详细说明的附加试验 或进行其他承运人规定的测试要求。

1.1 The main focus of this guide is to identify the key information required for United Nations (UN) packaging certification to ensure the selected packaging will be certified to the appropriate level for its intended use. This document also provides guidance for locating relevant sections of the United States Department of Transportation Title 49 Code of Federal Regulations (CFR). Consult with a regulatory specialist whenever needed. 1.2 This guide is intended to assist in determining the appropriate performance tests required to certify packaging designs to the United States Department of Transportation Title 49 Code of Federal Regulations performance oriented packaging standards based on the United Nations Recommendations on the Transport of Dangerous Goods. 1.3 This guide covers the testing for transportation of hazardous materials packagings for net masses not exceeding 400 kg (880 lb) or capacities not exceeding 450 L (119 gal), excepting packagings for infectious substances, radioactive materials, cylinders and other receptacles for gases. 1.4 This guide does not replace domestic or international regulatory requirements for hazardous materials packaging but is strongly recommended to be used in conjunction with those regulations. 1.5 The user of this guide must be trained in accordance with the United States Department of Transportation Title 49 Code of Federal Regulations (49 CFR) as required by 172.700 and should be familiar with other applicable hazardous materials regulations such as; International Civil Aviation Organization (ICAO) Technical Instructions for the Safe Transport of Dangerous Goods by Air, and the International Maritime Dangerous Goods Code (IMDG Code) and carrier rules such as International Air Transport Association (IATA) Dangerous Goods Regulations. 1.6 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. 1.7 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 and health practices and determine the applicability of regulatory requirements prior to use. ====== Significance And Use ====== The UN performance tests are based on the degree of hazard presented by the proposed hazardous material(s) to be packaged. Substances and articles which are hazardous are assigned to a specific packing group as defined in 3.8.1 and may be determined by referencing 49 CFR 172.101 hazardous materials table. Only packaging designs that have been successfully tested to the UN performance standards as defined in 3.8.2 may be marked with a UN mark. Hazardous Materials may not be transported in a packaging that does not bear the appropriate UN markings unless otherwise authorized by the applicable competent authority. Packages successfully tested to the UN performance standards may or may not withstand the North American distribution environment. To further evaluate the suitability of the package it is strongly recommended that additional tests as detailed in Practice D 4169 or other carrier specified test requirements be conducted.
