NIOSH Analytical Method, Sodium Hydroxide, S381, (Set 3).
NIOSH 1977 Nov:8 pages
The method is described for determining sodium-hydroxide (1310732) in the air, including the principle, range and sensitivity, interferences, precision and accuracy, advantages and disadvantages, apparatus, reagents, calibration and standards, and calculations. The principle is based upon determining the difference between the known amount of hydrochloric-acid added to the sample and the amount of acid remaining after extraction. The range is 0.76-3.9 milligrams per cubic meter with a precision of 0.062 (coefficient of variation). The OSHA standard is 2 milligrams per cubic meter.
