1.1 本试验方法适用于装有液体危险品（危险品）的中型散装容器（IBC）的振动试验，适用于任何设计或材料类型的IBC的试验。根据美国运输部标题49《联邦法规》（CFR）和联合国危险货物运输建议（UN），本试验方法是IBC资格认证的一部分。 1.2 本试验方法适用于测试450至3000 L（119至793 gal）的中型散货箱。应使用试验方法对较小尺寸的包装进行试验 D999 或其他适用方法。 1.3 ISO 2247标准可能不符合本试验方法的要求。 1.4 本试验方法基于49 CFR，§178.819中包含的当前信息。 1.5 本试验方法用于确定IBC是否保持完整性，并防止运输过程中内容物泄漏或溢出。该试验方法也可用作筛选工具或设计鉴定试验。其他振动方法可用于更紧密地模拟实际运输中经历的振动。 1.6 当测试用于危险材料（危险品）的包装设计时，应根据49 CFR§172对本测试方法的用户进行培训。 700和其他适用的危险品法规，如ICAO技术说明、IMDG规范和承运人规则，如IATA危险品法规。 1.7 以国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 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。 第节给出了具体的预防说明 6. . 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 当运输车辆受到振动时，集装箱会受到复杂的动态应力。为了接近运输过程中遇到的实际损坏或没有损坏，可能需要对集装箱和内含物进行振动输入。 4.2 装运期间的共振反应可能很严重，并可能导致容器故障和内容物溢出或泄漏。 识别临界频率和封装应力的性质有助于最小化这些事件的影响。 4.3 该振动试验方法用于CFR中IBC的鉴定 49并已在运输中成功使用。 4.4 暴露在振动中可能会影响运输集装箱、其封闭方式及其内容物。该测试方法允许分析这些组件的相互作用。可以利用对其中一个或多个组件的设计修改来实现运输环境中的最佳性能。 4.5 本试验方法适用于在车辆底座上自由运输的单个填充容器。 4.6 本试验方法不适用于以导致容器发生共振的频率对中间散装容器进行试验。

1.1 This test method covers vibration testing of filled intermediate bulk containers (IBCs) intended to contain liquid hazardous materials (dangerous goods) and is suitable for testing IBCs of any design or material type. This test method is required as part of the qualification of IBCs in accordance with the United States Department of Transportation Title 49 Code of Federal Regulations (CFR) and the United Nations Recommendations on the Transport of Dangerous Goods (UN). 1.2 This test method is appropriate for testing IBCs ranging from 450 to 3000 L (119 to 793 gal). Packagings of smaller sizes should be tested using Test Method D999 or other applicable methods. 1.3 The ISO 2247 standard may not meet the requirements for this test method. 1.4 This test method is based on the current information contained in 49 CFR, §178.819. 1.5 This test method is used to determine that the IBC maintains integrity and to prevent leakage or spillage of contents during shipping. This test method may also be used as a screening tool or as a design qualification test. Other vibration methods are available to more closely simulate vibration experienced in actual transportation. 1.6 When testing packaging designs intended for hazardous materials (dangerous goods), the user of this test method 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. The values given in parentheses are for information only. 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. Specific precautionary statements are given in Section 6 . 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 Shipping containers are exposed to complex dynamic stresses when subjected to vibration present in transportation vehicles. Approximating the actual damage, or lack of damage, experienced in shipping may require subjecting the container(s) and contents to vibration inputs. 4.2 Resonant responses during shipment can be severe and may lead to failure of the container and spillage or leakage of contents. Identification of critical frequencies and the nature of package stresses can aid in minimizing the effect of these occurrences. 4.3 This vibration test method is used for the qualification of IBCs in CFR 49 and has demonstrated successful use in transportation. 4.4 Exposure to vibration can affect the shipping container, its means of closure, and its contents. This test method allows analysis of the interaction of these components. Design modification to one or more of these components may be utilized to achieve optimum performance in the shipping environment. 4.5 This test method is suitable for individual filled containers that are transported unrestrained on the bed of a vehicle. 4.6 This test method is not intended for testing intermediate bulk containers at a frequency that causes the container to go into resonance.
