ASTM D5337-23

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3. Terminology
3.1 For definitions of terms used in this practice, refer to Terminology D1356.
3.1 Definitions of Terms Specific to This Practice (otherwise, refer to Terminology D1356):
3.1.1 traceability, n—property of a measurement result whereby the result can be related to a reference through a documented
unbroken chain of calibrations, each contributing to the measurement uncertainty.
3.2 The term primary flow-rate calibration, as used in this practice, does not imply the calibration is traceable to a primary
standard, unless the apparatus used in the calibration (burets, stop-watches, etc.) has been demonstrated to be traceable to national
or international standards, and that this traceability is established on a routine (generally annual) basis. Traceability of calibration
is strongly recommended.
4. Summary of Practice
4.1 A bubble tube meter or electronic near-frictionless pump flow meter is used for primary calibrationsetting and verifying the
flow rate of personal sampling pumps. The practice is applicable to systems using air sampling devices. Provisions are made for
both manual and automated bubble meters.
4.2 The verification of flow rates using equipment demonstrated to be traceable to national or international standards is required,
and the traceability of all measurement results involved in the determination of flow rate should be established on a routine
(generally annual) basis. Correction of measurement results is allowed, for example, for rotameters and mass flow meters, where
the results from sensors in the field measurement of the parameters used in the corrections are also traceable. Organizations which
perform traceable calibration of equipment should be accredited under ISO/IEC 17025 by an organization certified to do so under
ISO/IEC 17011.
4.3 Secondary calibration procedures for field applications are also included in the practice (seeIn older documents flow meters
with traceable calibrations have been referred to as “primary standards,” and those without as “secondary standards.” However,
primary standard and secondary standard have different definitions in metrology, and so those terms should not be applied here.
In metrology, both types of flow meters used in this practice are referred to as “working standards,” with 7.3). or without
traceability of calibration.
5. Significance and Use
5.1 Most occupational exposure assessment methods require the use of personal sampling pumps to collect air samples at typical
workplace sampling flow 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 in the measurement of the air volume(s)
sampled.
6. Apparatus
6.1 Sampling train, including a sampling pump, tubing, sampling substrate, and sampler (Test Method D4532), with either bubble
burette (6.2) or electronic flow meter (6.3) and other accessories as required (6.4).
6.2 Burets, Bubble burettes, 1-L1 L (for high flow) and 100-mL or 10 mL 100 mL or 10 mL (for low flow).
6.2.1 Bubble trap, to trap bubbles before reaching a sampler.

example, automated bubble meter, dry piston), thermal mass flow meter, and orifice flow meter. Any flow meter with traceability of calibration can be
used.
NOTE 2—Some flow meters recommend a pulsation dampener between a sampling pump and the flow meter. Refer to the manufacturer’s
instructions.should have traceable calibration (see 3.2).
