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

Significance and Use

Sulfuric acid is used in the manufacture of fertilizer, explosives, dyestuffs, other acids, parchment paper, glue, and the pickling of metal.

This test method has been found satisfactory for measuring sulfuric acid at levels required by federal occupational health regulations.


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.

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.
