Overview

This standard defines relevant requirements set out in Annex I of the new EC Machinery Directive 2006/42/EC, relating to machines 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 European Standard deals with the significant hazards, hazardous situations and events relevant to the following machinery for grinding and processing of flour and semolina, as defined in clause 3: roller mills, plan sifters and rotary separators, air classifiers, rotating machines and impact machines. The machines in the scope are stationery (not intended to be moved when in operation), have a capacity of at least 100 kg/h, and are intended for use in installations for grain processing, such as flour mills, semolina mills, grain cleaning and flaking plants. This European Standard deals with the significant hazards during commissioning, operation, cleaning and maintenance of the machines in the scope when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. This European Standard is not applicable to: machines intended for household use or laboratory use, stone mills, equipment for dampening and heating, auxiliary equipment for conveying, weighting and bagging (without changing the characteristics of the products). This European Standard is not dealing with the following: hazards related to decommissioning, the hazards of the installations into which the machines are incorporated other than those directly related to the machines in the scope (such as start of the installation, disconnection of energy supply, need from an emergency stop device), hazards due to the use of the machinery in a potentially explosive atmosphere. When drawing up this standard, it has been assumed that the machinery in the scope, if designed and used in accordance with this European Standard, is not creating itself a hazardous atmosphere wholly of partly surrounding it. If the machine is intended for use in a potentially explosive atmosphere, additional safety measures can be necessary. This European Standard is not applicable to machines for grinding and processing of flour and semolina which were manufactured before the date of its publication as an EN. This standard contains the German version of EN 14958:2006+A1:2009 which has been prepared by Technical Committee CEN/TC 153 "Machinery intended for use with foodstuffs and feed" of the European Committee for Standardization (CEN). The following changes have been made with respect to DIN EN 14958:2007: a) The standard has been changed and adapted with respect to the new Machinery Directive 2006/42/EC; b) An informative Annex ZB on the relationship between this European Standard and the Essential Requirements of Machinery Directive 2006/42/EC has been added. The national interests during the preparation of the standard were represented by Committee NA 060-18-07 AA "Nudelherstellungs- und Getreideverarbeitungsmaschinen" ("Pasta processing plant") of Technical Section "Food Processing Machinery" of the Mechanical Engineering Standards Committee (NAM) at DIN. Representatives of the interested parties were involved in the preparation of this standard.
