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 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.

Smaller filters recommended for sampling inside welding hoods.
