DIN EN ISO 12499:2010-12

This standard contains the German version of EN ISO 12499 which has been prepared by Technical Committee ISO/TC 117 "Fans" of the European Committee of Standardization (CEN). The secretariat is held by the BSI, United Kingdom. The national interests during the preparation of this standard were represented by Technical Section Air handling technology of the Mechanical Engineering Standards Committee (NAM) at DIN. This International Standard specifies requirements for the mechanical guarding of industrial fans. The circumstances under which safety measures shall be taken are described and information on how hazards can be reduced or eliminated is given, along with guidance on safety practices and information for use. This International Standard provides designers, users and installers with information on the safety aspects of fixed guards for use with industrial fans. Since fans, by the nature of the function they perform, contain rotating parts, they present a mechanical hazard which has to be minimized or avoided. As a fan does not usually have to be accessible during "normal operation", fixed guards can be applied. These can be removed during "ancillary operations" as necessary for servicing or maintenance. As the scope of this International Standard covers a particular form of guarding, the design, construction and use of which shall only be applied for a specific range of products, it is a type C standard, as defined by the European Committee for Standardization.
