Establishes the adoption as an Australian Standard of BS 6691:Part 1:1986 with amendments as described in the Preface. The Standard provides guidance on methods for the sampling and analysis of particulate matter in fume from welding and allied processes.

This Part of BS 6691 provides guidance on methods for the sampling and analysis of particulate matter in fume from welding and allied processes.NOTE 1. Advice on sampling strategy may be obtained from HSE Guidance Note EH 42.NOTE 2. The titles of publications referred to in this standard are listed on the back cover.
