DIN EN 741:2011-06

This standard defines relevant requirements set out in Annex I of the 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 standard specifies the special safety requirements for those types of fixed pneumatic handling systems and components which are designed for conveying bulk materials on a continuous or an intermittent basis (batch conveying system) from the loading point(s) to the unloading point(s). This European standard deals with the technical requirements to minimise the hazards. These hazards can arise during the operation and the maintenance of the pneumatic conveying systems when these activities are carried out in accordance with the specifications given by the manufacturer or his authorised representative. Annex A gives a list of hazards according to EN ISO 12100-1. The safety requirements and/or measures are specified in the same order as they are given in Annex A. The standard applies to design, on site assembly, and commissioning stages. The standard applies also to the built-in actuators and parts of the systems, which control the components. This standard contains the German version of EN 741:2002+A1:2010, which has been prepared by Technical Committee CEN/TC 148 "Continuous handling equipment and systems - Safety" of the European Committee of Standardization (CEN). The following modifications have been made with respect to DIN EN 741:2000-03: a) The standard has been modified and adapted with respect to the new Machinery Directive 2006/42/EC; b) modification of Annex ZA with reference to the new Machinery Directive 2006/42/EC. The national interests during the preparation of the standard are represented by Committee NA 060-22-31 AA "Stetigförderer" ("Continuous handling equipment") of Technical Section "Material handling" of the Mechanical Engineering Standards Committee (NAM) at DIN. Representatives of manufacturers and users of continuous handling equipment as well as representatives of professional and trade associations are involved in the preparation of the standard.
