Establishes the adoption as an Australian Standard of BS 6691:Part 2:1986 with amendments as described in the Preface. The Standard provides guidance on methods for the sampling and analysis of pollutant gases which may be produced or be present during welding and allied processes.

This Part of BS 6691 provides guidance on methods for the sampling and analysis of the following pollutant gases that may be produced or be present during welding and allied processes:ozone (O3)carbon monoxide (CO)carbon dioxide (CO2)nitric oxide (NO) and nitrogen dioxide (NO2)NOTE. The titles of the publications referred to in this standard are listed on the back cover.
