Scope

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.
