1.1This practice covers the use of a peristaltic pump for sampling liquids from multiple depths. It is applicable for a wide range of fluids including: high-viscosity fluids, aggressive and corrosive fluids, high-purity solutions, and abrasive fluids. It is especially useful for sampling liquids that require complete isolation from the pump.
1.2This practice includes the determination of sample depth, pump setup, and collecting a sample to be analyzed.
1.3This practice is not intended to give detailed instructions for running a peristaltic pump or to recommend which peristaltic pump to purchase. It instructs the field personnel how to connect the pump and collect a sample.
1.4Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard.
1.5This 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.
1.6This 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.
