This standard prescribes a procedure for sampling fumes generated by welding and allied processes. Because it is limited to health hazard evaluation, the standard is primarily concerned with sampling at the worker's breathing zone (see 4.1). It also prescribes procedures for general area sampling of fumes. However, the sampling methods described by this standard apply only to the sampling of solid particulate matter.

Safety and health issues and concerns are beyond the scope of this standard, and therefore are not fully addressed herein. Safety and health information is available from other sources, including, but not limited to, ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes, and applicable federal and state regulations.

This standard makes sole use of the International System of Units (SI).
