1.1 本规范涵盖通过旋转模塑成型成一体式无缝结构的平底直立圆柱形储罐。储罐由聚乙烯制成，用于地面垂直安装，能够在大气压下容纳侵蚀性化学品。包括材料、性能、设计、施工、尺寸、公差、工艺和外观要求。油箱容量为1900升（500加仑）以上。 1.2 本规范涵盖了在大气压下使用的文具容器的设计，该容器用于加热低于闪点的液体，对于I型储罐，连续工作温度低于66°C（150°F），对于II型储罐，连续工作温度低于60°C（140°F）。 1.2.1 NFPA标准 对于符合这些标准要求的安装，应咨询30和NFPA 31。 1.3 对于超出本规范范围的服务要求( 1.2 )，例如外部施加的机械力、内部压力或真空、高温服务等，应咨询其他相关标准来源，例如地方和州建筑规范、NFPA、ASME、ARM等。 1.4 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 注1: ISO 13341:2005+A1:2011和ISO 13575: 2012年类似，但不等同于本标准。 1.5 以下预防性警告仅适用于试验方法部分第节 11 ，本规范: 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。 1.6 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。

1.1 This specification covers flat-bottom, upright, cylindrical tanks molded in one-piece seamless construction by rotational molding. The tanks are molded from polyethylene for above ground, vertical installation and are capable of containing aggressive chemicals at atmospheric pressure. Included are requirements for materials, properties, design, construction, dimensions, tolerances, workmanship and appearance. Tank capacities are from 1900 L (500 gal) up. 1.2 This specification covers the design of stationery vessels for use at atmospheric pressure intended for use with liquids heated below their flash points and continuous service temperatures below 66°C (150°F) for Type I tanks and below 60°C (140°F) for Type II tanks. 1.2.1 NFPA Standards 30 and NFPA 31 shall be consulted for installations that are subject to the requirements of these standards. 1.3 For service requirements beyond the scope of this specification ( 1.2 ), such as externally imposed mechanical forces, internal pressure or vacuum, higher temperature service, etc., other relevant sources of standards, for example, local and state building codes, NFPA, ASME, ARM, etc., shall be consulted. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. Note 1: ISO 13341:2005+A1:2011 and ISO 13575:2012 are similar, but not equivalent to this standard. 1.5 The following precautionary caveat pertains only to the test methods portion, Section 11 , of this specification: 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. 1.6 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.
