This European amendment defines relevant requirements set out in Annex I of the new EC Machinery Directive 2006/42/EC, relating to thermal cleaning systems for exhaust gas which were placed on the European Economic Area (EEA) market for the first time, with the intent of simplifying the means of proving conformity with such requirements. Once this standard is designated a harmonized standard in the Official Journal of the European Communities, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (the so-called presumption of conformity). This standard deals with the machine-specific significant hazards, describes the related safety requirements and/or protective measures and requirements for the information for use. This standard contains the German version of Amendment A1:2010 to EN 12753:2005, which has been prepared by Technical Committee CEN/TC 271 "Surface treatment equipment - Safety" of the European Committee of Standardization (CEN). The national interests during the preparation of the standard were represented by the Mechanical Engineering Standards Committee (NAM) at DIN. Representatives of manufacturers and operators of surface treatment technology installations, as well as representatives of professional and trade associations were involved in the preparation of the standard.
