(Practice)Standard Practices for Sampling Water from Closed Conduits
Standard Practices for Sampling Water from Closed Conduits
SCOPE
1.1 These practices cover the equipment and methods for sampling water from closed conduits such as process streams at power stations for chemical, physical, microbiological, and radiological analyses. It does not cover specialized equipment required for and unique to a specific test or method of analysis. The following are included: SectionsPractice A-Grab Samples9 to 17Practice B-Composite Samples18 to 23Practice C-Continual Sampling24 to 29
1.2 For information on specialized sampling equipment, tests or methods of analysis, reference should be made to volumes 11.01 and 11.02 of the Annual Book of ASTM Standards, relating to water.
1.3 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazards statements, see 8.3 and 13.4.
