EN 1906:2012 (E) 4 Foreword This document (EN 1906:2012) has been prepared by Technical Committee CEN/TC 33 “Doors, windows, shutters, building hardware and curtain walling”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2012, and conflicting national standards shall be withdrawn at the latest by November 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1906:2010. Contribution to the preparation of this standard has been made by the European manufacturers' organisation "ARGE". This document is part of a series of European Standards dedicated to building hardware products. Compliance of a set of lock or latch furniture with this European Standard means that it conforms to requirements for normal use, for safety in use and for safety in case of fire. Normative and informative annexes to this document are indicated in the contents. Compliance with this European Standard ensures a margin of strength in excess of that needed for normal operation. Additional requirements are necessary for special safety furniture used in situations where there is a high risk of failure. Since special safety furniture is not essential in every situation, this European Standard provides additional safety requirements (see 5.13) which are only necessary when the manufacturer claims it essential that the safety furniture conform to these requirements. This document states five grades of security. Grade 0 is in accordance with requirements specified in the main part of this document. Grades 1 to 4 are specified in accordance with requirements for security lock furniture for use on burglary-resistant doors (see Annex A). These additional security requirements are necessary only when the manufacturer claims that products need have a high level of security, which is not essential in every situation. The suitability of lock or latch furniture for use on fire/smoke door assemblies is determined by fire performance tests in addition to the performance tests specified by this standard. Since suitability for use on fire/smoke door assemblies is not essential in every situation, the manufacturer has the option of stating whether the furniture is claimed to conform to these additional requirements or not. If such a claim is made, the additional requirements given in Annex C are necessary. Annex C refers to all kinds of lock or latch furniture for use on fire/smoke door assemblies, and their use on single-leaf or double-leaf doors. A product conforming to this standard can also be part of an exit device in accordance with EN 179. In order to claim conformance to EN 1906 all relevant requirements of Table 1, Main test parameters, should be met and declared. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, SIST EN 1906:2012

For reasons relating to designs of springs, the operating angle of such lever handles is usually restricted to 40°, and they are used with latches whose bolts retract fully at this angle of operation. When in use, the combined action of the lever handle spring and the latch spring is sufficient to return the lever handle to its intended "at-rest" position. 3.29 Sprung furniture door furniture that incorporates a spring which fully returns the lever handle or knob to its intended "at-rest" position after operating the latch Note 1 to entry: Sprung furniture frequently includes an internal stop to prevent rotation beyond the intended "at-rest" position, but this feature is not essential if the furniture is used with a latch mechanism incorporating its own stop. 3.30 thumb turn small T-handle, knob or other handle fitted on the internal plate of a set of bathroom lock furniture that operates a lock deadbolt to provide privacy rather than high security Note 1 to entry: See Figure 3.
