前言:这是CSA B625《危险货物运输用移动式罐》的第三版。它取代了2013年和2008年出版的前两个版本。本标准是为配合《危险品运输条例》使用而制定的一系列标准之一，这些条例通过引用采用了本标准。由于法规可能会在某些例外情况或附加要求下采用本标准，因此应始终结合本标准参考这些法规。范围:1.1本标准适用于联合国移动式储罐的设计和制造以及加拿大主管当局的批准。此类联合国便携式储罐的容量大于450升，可能符合或不符合国际海事组织1972年《国际集装箱安全公约》中“集装箱”的定义。 除本标准的规定外，除非另有规定，《1972年国际安全集装箱公约》的适用规定将适用于符合该公约条款中“集装箱”定义的任何移动式罐*其他规定可能适用于在公海中处理的海上移动式储罐。《国际集装箱安全公约》不适用于在公海装卸的海上罐式集装箱。海上罐式集装箱的设计和测试考虑了在恶劣天气和海况下在公海装卸罐时可能产生的动态提升力和冲击力。此类储罐的规定由批准的主管当局确定。本标准也适用于联合国便携式储罐的选择、使用、检查、测试和维修，以及IMO- 类型移动式罐（IMO类型1、2、5或7罐），以及IM 101和IM 102移动式罐，用于在加拿大处理、提供运输或运输危险品，无论其是否符合1972年《国际安全集装箱公约》中“集装箱”的定义*加拿大通过了《安全集装箱公约法》和《安全集装箱公约条例》，以实施该公约的规定。1.2根据本标准对产品进行的测试和评估可能涉及使用可能存在危险的工艺、材料和/或设备。本标准不涉及与其使用相关的职业健康和安全方面。使用本标准的任何人都有责任咨询相关部门，并结合任何适用的监管要求制定适当的健康和安全实践。 1.3 1992年《危险品运输法》和《危险品运输条例》可能规定了本标准之外或不同于本标准的要求。如果本标准的要求与法案或法规的要求不一致，则以法案或法规的要求为准。1.4本标准规定了有关移动式储罐的设计、施工、测试、选择和使用的某些最低要求。必须结合本标准进行有能力的判断。在某些情况下，有必要超过本标准的最低要求，以实现充分的公共安全。1.5在本标准中，“应”用于表示要求，即用户为遵守本标准而有义务满足的规定； “应该”用于表示建议或建议但不需要的建议；“可”用于表示一个选项或在标准范围内允许的选项。注释随附条款不包括要求或替代要求；随附条款的注释的目的是将解释性或信息性材料与文本分开。表和图的注释被视为表或图的一部分，可以作为要求编写。附件被指定为规范性（强制性）或信息性（非强制性）以定义其应用。

Preface:This is the third edition of CSA B625,Portable tanks for the transport of dangerous goods. It supersedes the previous editions, published in 2013 and 2008.This Standard is one of a series of Standards prepared for use in conjunction with theTransportation of Dangerous Goods Regulations, which adopt this Standard by reference. Because the Regulations may adopt this Standard with certain exceptions or additional requirements, they should always be consulted in conjunction with this Standard.Scope:1.1This Standard applies to the design and manufacture of UN portable tanks and their approval by the Competent Authority of Canada. Such UN portable tanks have a capacity greater than 450 L and might or might not meet the definition of "container" within the terms of the International Maritime Organization'sInternational Convention for Safe Containers, 1972.In addition to the provisions of this Standard, unless otherwise specified, the applicable provisions of theInternational Convention for Safe Containers, 1972would apply to any portable tank which meets the definition of a "container" within the terms of that Convention.*Additional provisions might apply to offshore portable tanks that are handled in open seas.The International Convention for Safe Containers does not apply to offshore tank containers that are handled in open seas. The design and testing of offshore tank containers takes into account the dynamic lifting and impact forces that might occur when a tank is handled in open seas in adverse weather and sea conditions. The provisions for such tanks are determined by the approving competent authority.This Standard also applies to the selection, use, inspection, testing, and repair of UN portable tanks, as well as IMO-type portable tanks (IMO-type 1, 2, 5, or 7 tanks), and IM 101 and IM 102 portable tanks, for handling, offering for transport, or transport of dangerous goods in Canada, whether or not they meet the definition of "container" within the terms of theInternational Convention for Safe Containers, 1972.*In Canada, the Safe Containers Convention Act and the Safe Containers Convention Regulations have been adopted to give effect to the provisions of the Convention.1.2The testing and evaluation of a product in accordance with this Standard can involve the use of processes, materials, and/or equipment that can be hazardous. This Standard does not address the occupational health and safety aspects associated with its use. Anyone using this Standard has the responsibility to consult the appropriate authorities and establish appropriate health and safety practices in conjunction with any applicable regulatory requirements.1.3TheTransportation of Dangerous Goods Act, 1992, and theTransportation of Dangerous Goods Regulationsmight set out requirements that are additional to or different from those in this Standard. Where there is an inconsistency between the requirements of this Standard and those of the Act or Regulations, the Act or Regulations takes precedence to the extent of the inconsistency.1.4This Standard sets out certain minimum requirements regarding the design, construction, testing, selection, and use of portable tanks. It is essential to exercise competent judgment in conjunction with this Standard. In some circumstances, it is necessary to exceed the minimum requirements of this Standard so that adequate public safety is achieved.1.5In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
