Standard Practice for Flow Rate for Calibration of Personal Sampling Pumps

SCOPE
1.1 This practice describes the calibration of sampling pumps commonly used for monitoring personal exposure to hazardous compounds in the work place.
1.2 This practice includes procedures for describing primary and secondary calibration techniques.
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.
