ASTM D 4597 Document Information:
Title
Standard Practice for Sampling Workplace Atmospheres to Collect Gases or Vapors with Solid Sorbent Diffusive Samplers
ASTM International
Publication Date:
Apr 10, 2003
Scope:
This practice covers the sampling of workplace atmospheres for the
presence of certain gases or
vapors by means of diffusion across a specified quiescent region and
subsequent sorption on a solid
sorbent (1).
A list of organic compounds which are applicable to solid sorbent
sampling where the sorbent is
contained in a bed through which air is passed is given in Annex A1 of
Practice D 3686. Diffusive
samplers may be applicable to a similar range of compounds but this
must be confirmed by reference
to the individual sampler manufacturers' literature.
The valid use of diffusive samplers depends on the existence of actual
laboratory or field
validation, or both. Guidance on validation can be obtained from
published protocols (2-6). This
practice is not designed to cover the verification, validation, or
specific test procedures used to
assess the accuracy or precision of diffusive samplers.
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.
