1.1 本规范涵盖了通过接触成型制造的圆柱形储罐，用于地面垂直安装，在大气压力下容纳侵蚀性化学品，由商业级聚酯或乙烯基酯树脂制成。包括材料、性能、设计、施工、尺寸、公差、工艺和外观要求。 1.2 本规范不包括拟用于大气压力以上或真空条件下的容器的设计，除非本文分类，或拟用于加热超过闪点的液体的容器。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.4 对于承受环境力和/或机械力（如地震力、风力、冰力、搅拌力或流体动力）的储罐，以及工作温度高于180°F（82°C）的储罐和底部无支撑的储罐，应特别考虑其设计。 1.5 以下安全隐患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。 注1: 没有已知的ISO等效于本标准。 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 cylindrical tanks fabricated by contact molding for above-ground vertical installation, to contain aggressive chemicals at atmospheric pressure, and made of a commercial-grade polyester or vinyl ester, resin. Included are requirements for materials, properties, design, construction, dimensions, tolerances, workmanship, and appearance. 1.2 This specification does not cover the design of vessels intended for pressure above atmospheric or under vacuum conditions, except as classified herein, or vessels intended for use with liquids heated above their flash points. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are provided for information purposes only. 1.4 Special design consideration shall be given to tanks subject to environmental and/or mechanical forces such seismic, wind, ice, agitation, or fluid dynamic forces, to operational service temperatures greater than 180°F (82°C) and to tanks with unsupported bottoms. 1.5 The following safety hazards caveat pertains only to the test method 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. Note 1: There is no known ISO equivalent to this standard. 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.
