ÖNORM EN 746-1

This document specifies the general safety requirements common to industrial furnaces and associated processing equipment (TPE). This document deals with the significant hazards, hazardous situations or hazardous events relevant to TPE, as listed in Annex A, when TPE is used as intended and also under conditions of misuse that are reasonably foreseeable by the manufacturer. Annex B provides a list of common industrial furnaces and associated processing equipment. This document specifies the requirements intended to be met by the manufacturer to ensure the safety of persons and property during commissioning, start-up, operation, shut-down, maintenance periods and dismantling, as well as in the event of foreseeable faults or malfunctions that can occur in the equipment. These general safety requirements apply to all TPE, unless an exception is given in other parts of EN 746 series dealing with specific equipment. The provisions of other parts of EN 746 that directly apply to specific types of TPE take precedence over the provisions of this document. This document is not applicable to - blast furnaces, direct reduction furnaces and gas converters; - steam and hot water boilers; - fired appliances in the refining, petrochemical and chemical industries; - sulphur thermal reactors ("Claus plants"). As long as no other standard is applicable for thermoprocess equipment (TPE), the requirements of this standard are applicable.
