Method 0500

Total Particulates Not Otherwise Regulated

This method is for the determination of the total dust concentration (particulates) using gravimetric determination.  After sample collection the filter is dried to a constant weight and the total particulate is determined by difference with the initial tared filter weight.

The method may be applied to fibrous glass in addition to the other ACGIH particulates not otherwise regulated.  The method is non-specific meaning it does not distinguish between the types of particulates.

The working range of the method is 1 to 20 mg/m³ for a 100 L air sample.

NOTE: This method replaces Method S349.
