ASTM D5337-04
(Practice)Standard Practice for Flow Rate for Calibration of Personal Sampling Pumps
Standard Practice for Flow Rate for Calibration of Personal Sampling Pumps
SIGNIFICANCE AND USE
Most occupational exposure assessment methods require the use of personal sampling pumps to collect air samples at typical workplace sampling rates, with sampling volumes specified by (a) particular procedure(s). The precision and bias of these methods are directly affected by the precision and bias of the pumps used to measure the air volume(s) sampled.
SCOPE
1.1 This practice describes the calibration of sampling pumps commonly used for monitoring personal airborne exposures in the work-place.
1.2 This practice includes procedures for describing primary and secondary calibration techniques.
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.
