This European Standard specifies requirements and test methods for durability, strength, security and function of mechanically operated multipoint locks and their locking plates for use in doors, window doors and entrance doors in buildings. This standard covers systems comprising more than one locking point or anti-separation point or clenching point between door leaf and frame, interlinked and centrally controlled and /or operated. Multipoint locks and their locking plates used in fire resistant and/or smoke control door assemblies require additional attributes to comply with the Essential Requirement "Safety in case of fire" either independently, or as a part of a complete assembly. Additional requirements for multipoint locks and their locking plates used on fire resistant and/or smoke control door assemblies are specified in annex A. This European Standard covers multipoint locks which are either manufactured and placed on the market in their entirety by one producer or assembled from sub-assemblies produced by more than one producer and subsequently placed on the market as a kit in a single transaction. This standard specifies only the dimensions and properties required for security and for the assessment of smoke door suitability. This standard does not specify any particular design or installation. The suitability of an electrically operated multipoint lock is determined by additional performance tests specified in WI 33062 This European standard does not specify single point locks or their locking plates which are specified by EN 12209. This European standard is not applicable to cylinders, handles, locks for windows, padlocks, locks for safes, furniture locks or prison locks. This standard specifies Multipoint locks and locking systems intended for use in different environmental and security conditions, thus necessitating different grades.
