  • Abstract:
    EN 746-3 specifies safety requirements for protective and reactive atmosphere gas systems and their generation and use in industrial thermoprocessing equipment and associated plants, including systems in which the protective and reactive gases are produced by reaction within the thermoprocessing plant. It applies to the supply of protective and reaction atmosphere gases, gaseous and liquid additions to, and their removal from industrial thermoprocessing equipment and associated plants, confined to the equipment integrated in these installations. The general safety requirements common to TPE are provided in EN 746-1. EN 746-3 deals with significant hazards, hazardous situations and events relevant to the generation and use of protective and reactive atmosphere gases created by thermochemical reactions and their use in TPE, when used as intended and under the conditions foreseen by the manufacturer.
