NF EN ISO 10882-2, A88-202-2 (05/2024)

This part of EN ISO 10882 gives guidance for determining personal exposure to organic gases and vapors in welding and related techniques. It applies to the following thermal processes used to join, cut, plate or remove metal: (111) Manual arc welding with coated electrode; (114) Arc welding with self-protecting cored wire; (131) MIG welding (arc welding under inert gas protection with fusible wire electrode); (135) MAG welding (arc welding under active gas protection with fusible wire electrode); (136) MAG welding with cored wire (Active gas shielded arc welding with cored wire); (137) MIG welding with cored wire (Inert gas shielded arc welding with cored wire); (141) TIG welding (arc welding under inert gas protection with tungsten electrode); (15) Plasma welding; (31) Oxygas welding; (52) Laser welding; (912) Strong gas brazing; (97) Welding; Arc and flame gouging; Arc and laser cutting processes; Flame, laser/plasma and plasma cutting processes; Metallization. [EN ISO 4063] The following organic gases and vapors, which may be produced or pre-existing during welding and related techniques, are covered: _ ozone (O3); _ carbon monoxide (CO); _ carbon dioxide (CO2); _ nitric oxide (NO) and nitrogen peroxide (NO2); _ organic vapors produced when welding or cutting metals painted or having another type of coating. Combustible gases, oxidizing gases and shielding gases used in welding and related techniques are not covered. General ambient concentrations of organic gases and vapors in the workplace atmosphere influence individual exposure, and therefore the role of fixed-point measurements is also considered.
