NIOSH 7401 (Issue 2)

Alkaline Dusts

This test method uses an acid-base titration technique to measure total alkalinity of alkali hydroxides, carbonates, borates, silicates, phosphates, and other basic salts, expressed as equivalents of NaOH. The method measures the total alkalinity of alkali hydroxides, carbonates, borates, silicates, phosphates, and other basic salts. This revises Methods S381 and P&CAM 241.

Analysis Type (Application Method): Acid-base titration
