    Significance and Use

    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. Scope

    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.
