Foreword
This document (EN 746-1:1997/prA1:2009) has been prepared by Technical Committee CEN/TC 186
“Industrial thermoprocessing - Safety”, the secretariat of which is held by DIN.
This document is currently submitted to the Unique Acceptance Procedure.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annexes ZA and ZB, which are integral parts of this
document.
The new safety requirements as stated in this document comply with the additional relevant Essential
Requirements of the new Machinery Directive 2006/42/EC complementing the existing Machinery Directive
98/37/EC.
Once this document is cited in the Official Journal of the European Community under the new Machinery
Directive 2006/42/EC and has been implemented as a national standard in at least one member state, it
confers a presumption of conformity with the new relevant Essential Requirements of that new Directive and
associated EFTA regulations.
This standard forms one part of a series safety standards covering Industrial Thermoprocessing Equipment.
The full list of parts of EN 746 is given below:
EN 746 Industrial thermoprocessing equipment
Part 1: Common safety requirements for industrial thermoprocessing equipment
Part 2: Safety requirements for combustion and fuel handling systems
Part 3: Safety requirements for the generation and use of atmosphere gases
Part 4: Particular safety requirements for hot dip galvanising thermoprocessing equipment
Part 5: Particular Safety Requirements for Salt Bath Thermoprocessing Equipment
Part 6: Particular Safety Requirements for Material Melting, Remelting and Liquid Phase
Maintaining Thermoprocessing Equipment
Part 7: Particular Safety Requirements for Vacuum Thermoprocessing Equipment
Part 8: Particular safety requirements for quenching equipment
EN 1547 Industrial thermoprocessing equipment — Noise test code for industrial thermoprocessing
equipment including its ancillary handling equipment
An assessment of the foreseeable risks arising from the use of the equipment was carried out when this
standard was prepared.
