Standard Test Method for
Determination of Sulfuric Acid Mist in the Workplace
Atmosphere (Ion Chromatographic)1

This standard is issued under the fixed designation D 4856; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This ion chromatographic test method describes the
determination of sulfuric acid mist in air samples collected
from workplace atmospheres in a three-piece cassette filter.

1.2 The lower detection limit of this test method is 0.017
mg/m3 of sulfuric acid (H2SO4) mist in 60 L of air sampled at
1 L/min.

1.3 This test method is relatively free from interference. The
only known interference is soluble or partially soluble sulfate
salts.

1.4 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. For specific
precautionary statements, see Section 9.
