fischer Catalogue Installation Systems Mounting sprinkler systems. Sprinkler systems are usually created according to different standards. For example, according to the VdS standard (VdS CEA 4001), the American FM standard 1951 (Factory Mutual Insurance Company" (FM Global)), UL 203 (Underwriters Laboratories (UL)), NFPA 13 regulations (National Fire Protection Association (NFPA)) or EN 12845. The European Directive CEA 4001 was created in 1995 by the insurance industry in cooperation with the manufacturers' association EUROFEU, and VdS CEA 4001 was created in Germany in 2003 by the "Association of Property Insurers" (VdS). EN 12845 was developed on the basis of CEA 4001 from 1995 and the VdS CEA 4001 from 2003, creating a standard that was practically the same word for word. National practices, such as those for Germany, are to be included in a revised DIN 14489 as a national annex to EN 12845. The American rules correspond to the requirements for mounting pipe installations ,but they must be checked in detail in each case. For mounting sprinkler pipes, the different load values, mounting distances and connection sizes for pipe loops and pipe clamps, which are listed in the following table for the most common directives, are applicable. 10 Load values. fixing distances and connection sizes for pipe loops and pipe clamps for the most common guidelines FM1951 468 NFPA13 VdS CEA 4001 Test load calculated Max. distance Min. rod size Loading capacity Max.
