Start of application The start of application of this standard is 1 October 2010. National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee CEN/TC 186 “Industrial thermoprocessing Safety" (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-03-02 AA Industrielle Thermoprozessanlagen Sicherheit of Section Thermoprozesstechnik. Representatives of manufacturers and users of thermoprocessing equipment, and of the employers' liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the new “Machinery Directive", Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements ofthedirectives. Once this standard is cited in the Official Journal of the European Union, it is deemed a "harmonized' standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive ("presumption of conformity"). The European Standards referred to in Clause 2 and in the Bibliography of the EN have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. For the International Standards referred to in this standard there are no national standards available unless they have been published as DIN ISO standards with the same number. Amendments This standard differs from DIN EN 746-2:1997-05 as follows: Subclause 5.7 "Design requirements for electrical and electronic equipment for control system and a) protective system" has been included; b) Annex ZA (informative) "Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC" has been included. and therefore do not affect the English text: a) in Subclause 5.2.2.3.3, last paragraph, the text following the first item: " in case of high temperature equipment;" (im Falle von Hochtemperaturanlagen) has been deleted; b) some typing errors have been corrected.
