Scope

1.1 This test method covers a procedure for the determination of both total collected particulate matter and extractable mass metal removal fluid aerosol concentrations in the range of 0.05 to 5 mg/m³ in workplace atmospheres.

1.2 This test method describes a standardized means of collecting worker exposure information that can be compared to existing exposure databases, using a test method that is also more specific to metal removal fluids.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.

Significance and Use

This test method covers the gravimetric determination of metal removal fluid aerosol concentrations in workplace atmospheres.

The test method provides total particulate matter concentrations for comparison with historical exposure databases collected with the same technology.

The test method provides an extension to current nonstandardized methods by adding an extractable mass concentration which reduces interferences from nonmetal removal fluid aerosols.

The test method does not address differences between metal removal fluid types, but it does include extraction with a broad spectrum of solvent polarity to remove any of the current fluid formulations from insoluble background aerosol adequately.

The test method does not identify or quantify any specific putative toxins in the workplace that can be related to metal removal fluid aerosols or vapors.

The test method does not address the loss of semivolatile compounds from the filter during or after collection.
