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.

Analysis for this analyte is based on water solubility.

Special requirements

* 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.
