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. This specification does not cover the design of vessels intended for use at pressures other than atmospheric pressure. Furthermore, this specification does not cover the design of portable tanks and is not for vessels intended for use with liquids heated above their flash points in continuous service. Special design considerations not covered in this specification shall be given to vessels subject to superimposed mechanical forces, such as seismic forces, wind load or agitation; to vessels subject to service above specified temperature; and vessels subject to specified superimposed pressure of water. Low-temperature impact test shall be performed on rotational-molded polyethylene tanks. The test method is used on tanks molded from both the crosslinked and non-crosslinked polyethylenes. Dart drop impact test shall be performed to determine the quality of the tank. O-xylene-insoluble fraction or gel test shall be performed on crosslinked polyethylene. Visual inspection and water test shall also be performed on the samples.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.

5.1 This practice is intended to assist field personnel in obtaining samples from tanks for laboratory analysis. The cost associated with sampling and analysis, along with other reasons, make it essential that samples be taken correctly before submitting them for chemical analysis, physical testing, or both. Incorrect sampling can invalidate resulting data.5.2 This practice provides guidance in choosing the sampling technique and equipment suitable for specific situations. It is recommended that this guide be used as a supplement to a written field sampling plan.5.3 The procedures for sampling tanks using a COLIWASA, liquid profiler sampler, bacon bomb sampler, and peristaltic pump and tubing are delineated.1.1 This practice covers information for field personnel to follow in order to collect samples from tanks.1.2 The purpose of this practice is to help field personnel in planning and obtaining samples from vertical and horizontal tanks, open-topped rectangular/square tanks, railroad and truck tankers, vacuum trucks, and tanks with multiple compartments using equipment and techniques that will assist in meeting the sampling objectives.1.3 The practice is applicable to hazardous materials, products, raw materials, by-product, or waste.1.4 Sampling from circulating pump discharge valves and tank transfer lines is not addressed in this practice.1.5 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.6 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.1.7 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.
