31、d the United Kingdom. BS EN 795:2012EN 795:2012 (E) 6 Introduction A reliable anchor device is an essential component of any personal fall protection system. This European Standard is intended to act as a complementary standard for existing European Standards covering other components used in person

32、al fall protection systems. The scope and the requirements are based on the philosophy that anchor devices are rated to sustain the maximum dynamic force generated in a fall from a height by the mass of one person, including any equipment carried. The static strength tests are based on a minimum fac

33、tor of safety of two. To allow for foreseeable misuse of equipment, this European Standard provides requirements and test methods for anchor devices used in personal fall protection systems in accordance with EN 363, even if their intended use is for restraint. Requirements and test methods for mult

34、i-user anchor devices, i.e. anchor devices that allow more than one user to be attached at any one time, are not addressed in this document but advice is provided in a separate CEN Technical Specification. This European Standard is intended for the type testing of new products before placing them on

35、 the market and gives only minimum performance requirements. It is essential that anchor devices are designed and manufactured so that, in the foreseeable conditions of use for which they are intended, the user is able to perform the risk-related activity while being appropriately protected at the h

36、ighest possible level. Manufacturers may wish to bear these points in mind when deciding on the actual performance of their products. BS EN 795:2012EN 795:2012 (E) 7 1 Scope This European Standard specifies requirements for performance and associated test methods for single-user anchor devices which

37、 are intended to be removable from the structure. These anchor devices incorporate stationary or travelling (mobile) anchor points designed for the attachment of components of a personal fall protection system in accordance with EN 363. This European Standard also gives requirements for marking and

38、instructions for use, and guidance on installation. This European Standard is not applicable to: anchor devices intended to allow more than one user to be attached at any one time; anchor devices used in any sports or recreational activity; equipment designed to conform to EN 516 or EN 517; elements

39、 or parts of structures which were installed for use other than as anchor points or anchor devices, e.g. beams, girders; structural anchors (see 3.3). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applic
