Scope
This International Standard specifies a method for the determination of the time-weighted average
mass concentration of hexavalent chromium in workplace air.
Separate sample preparation methods are specified for the extraction of soluble and insoluble
hexavalent chromium. The method for insoluble hexavalent chromium can also be used to prepare
samples for determination of total hexavalent chromium, if desired.
This International Standard is applicable to the personal sampling of the inhalable fraction of airborne
particles, as defined in ISO 7708, and to static (area) sampling. The analytical method is applicable to
the determination of masses of 0,01 μg to 10 μg of hexavalent chromium per sample, without dilution.
The concentration range of hexavalent chromium in air for which the measuring procedure is applicable
is determined by the sampling method selected by the user (see 10.1). For a 1 m3 air sample, without
sample dilution, the working range is approximately 0,01 μg·m−3 to 10 μg·m−3.
