Notes

Results are provided for the presence and amount or concentration of a specific element or elements. The stated identity of the actual sample contents (such as specific form, valence state, or compound) is based on the assumption that the material sampled is as identified by the compliance officer using available documentation of materials and processes.

If the filter is not overloaded, samples may be collected up to an 8-hour period. Results are provided for the presence and amount or concentration of a specific element or elements. The stated identity of the actual sample contents (such as a specific form or compound) is based on the assumption that the material sampled is as identified by the compliance officer using available documentation of materials and processes. The physical form of a sample (dust, mist, or fume) is identified by the compliance officer using available documentation of materials and processes.

Special requirements

For the entire suite of analytes listed in METALSSG-2, request analyte code 2587.

For the entire suite of analytes listed in METALSSG-3, which may be found during soldering and brazing operations, request analyte code S131.

* All sampling instructions above are recommended guidelines for OSHA Compliance Safety and Health Officers (CSHOs), please see the corresponding OSHA method reference for complete details.
