CEN/TC 186/WG 1 - Industrial furnaces and heating equipment - Common safety requirements

1.1   This part of EN 746 specifies common safety requirements for industrial thermoprocessing equipment (for example industrial furnaces and industrial heating equipment), which meets the definition for machinery given in EN ISO 12100-1:2003.
It details the anticipated significant hazards associated with industrial thermoprocessing equipment and specifies the appropriate preventative measures for reduction or elimination of these hazards.
This standard gives general principles and common requirements for the reduction of risks for equipments covered by the scope.
The common requirements apply to all of the subsequent parts of this EN 746 dealing with specific equipment unless an exception is stated in the relevant Part. The general principles (subclauses are pointed out) will be used to establish the specific technical measures in the subsequent Part(s) dealing with safety requirements for particular equipment.
NOTE   For similar equipment not covered by the particular Parts of this standard, EN 746-1 can be used to assist in the reduction of risk for the Hazards identified in clause 4 (List of Hazards).
1.2   This part of EN 746 is applicable to industrial thermoprocessing equipments for use in fields such as:
-   Metallurgical and metal working plant;
-   Glass making plant;
-   Ceramic manufacturing plant;
-   Cement, lime and gypsum manufacturing plant;
-   Chemical plant;
-   Waste incineration equipment;
And heated by:
-   Gaseous fuels;
-   Liquid fuels;
-   Solid fuels;
-   Mixed fuels;
-   Electricity.
The thermoprocessing equipment covered by this Part of EN 746 is further specified in clause 3.
A more detailed list of thermoprocessing equipment within these categories is given in Annex A.
In the remainder of this standard the expression "equipment" will be used.
This Part of EN 746 is not applicable to blast furnaces, converters (in steel plants), boilers, welding machines or food processing equipment.
1.3   This Part of EN 746 specifies the requirements to be

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

1.1 This part of prEN 746 specifies common safety requirements for industrial thermoprocessing equipment (for example industrial furnaces and industrial heating equipment), which meets the definition for machinery given in EN 292-1:1991. It details the anticipated significant hazards associated with industrial thermoprocessing equipment and specifies the appropriate preventative measures for reduction or elimination of these hazards. This standard gives general principles and common requirements for the reduction of risks for equipments covered by the scope.
