This part of EN 746 specifies the requirements for protective systems used in industrial furnaces and associated processing equipment (TPE). The functional requirements to which the protective systems apply are specified in the other parts of the EN 746 series.

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. 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 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, converters (in steel plants), boilers, fired heaters (including reformer furnaces or cracking furnaces) in the petrochemical and chemical industries or equipment not covered under EN°ISO°12100. This document or parts of this document can be used to blast furnaces, converters (in steel plants), boilers, fired heaters (including reformer furnaces or cracking furnaces) in the petrochemical and chemical industries or equipment not covered under EN°ISO°12100
