Primary Laboratory Sampling/Analytical Method (SLC1):
- sampling media: tared 37-mm diameter low-ash polyvinyl chloride filter
maximum volume: 960 Liters
minimum volume: 480 Liters
maximum flow rate: 2.0 L/min
current analytical method: Gravimetric
method reference: OSHA Analytical Method (OSHA PV2121)
method classification: Partially Validated
note: OSHA personnel can obtain tared sampling media from the Salt Lake Technical Center.
note: If the net weight of the sample yields a concentration below the standard for the substance, the Salt Lake Technical Center will perform no further work on that sample. If the net weight corresponds to an amount greater than the standard, the sample may be analyzed for the appropriate element and the result reported as the substance.
current elemental analysis method: Atomic Absorption Spectroscopy; AAS
method reference: OSHA (In-House File)
method classification: Not Validated
