This European Standard specifies test methods and requirements for spindle and fastening elements, operating torques, permissible free play and safety, free angular movement and misalignment, durability, static strength and corrosion resistance for sprung and unsprung lever handles, knobs for doors, push pads and similar devices in combination with backplates or roses operating latches. This European Standard is applicable only to lever handles and knobs that operate a latch or a lock and other devices. It specifies four categories of use according to frequency and other conditions of use. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

This classification example denotes furniture for use by people with a high incentive to use care in a domestic situation, with durability grade 6 for medium frequency of use. There is no classification for door mass, it is not approved for fire/smoke doors, nor for safety applications and has a mild resistance to corrosion for internal use. It is not suitable for use on burglary-resistant doors and is of the unsprung type. 5 Requirements 5.1 General Sets of lock or latch furniture are in general similar executed groups. From this group the expected weakest assembly is subjected to the sequence of tests specified in 6.1, and listed in Table 1 using the test apparatus in accordance with 6.2 and the methods specified in Clause 7 and shall conform to 5.2 to 5.14. Results of a sequence of tests may be found to be applicable or conform to sets which are tested in another sequence of tests. If sets that are of equivalent construction on both sides of the door have been endurance tested, these sets cannot be passed on a one-sided movable knob set or lever handle set. For entrance sets, the equivalent set of lock or latch furniture shall be endurance tested to verify that the lever handles or knobs conform to the durability requirements. The entrance set assembly shall be tested in accordance with all other appropriate tests. Furniture that is made available with a lever one side and a knob on the other side shall be endurance tested accordingly. Sets of furniture shall be classified in grades 1 to 4 (see 4.1.2) in regard to performance requirements specified in 5.2 to 5.13. NOTE 1 If door furniture is to perform satisfactorily in service, it is essential that it is correctly selected for the application for which it is to be used and fitted strictly in accordance with the manufacturer's recommendations.
Materials in products shall not release any dangerous substances in excess of the maximum levels specified in the European material standards. NOTE 2 National regulations may also apply. SIST EN 1906:2012

The manufacturer should state clearly the door thickness or range of door thicknesses for which the furniture is suitable, and in the case of spring-assisted and spring-loaded furniture, the angle of rotation possible by the design (see 6.2.1.1 and 7.3.1). 5.3 Rotational torque strength When tested in accordance with 7.3.12, lock or latch furniture shall show no failure of any component and the lever handles or knobs shall still be operational after the test. Lever handles or knobs shall not deform permanently more than 5 mm as measured at (50 ± 2) mm from the axis of rotation by the dial gauge. 5.4 Axial strength of lock furniture or latch furniture and fixing When tested in accordance with 7.3.2, there shall be no failure of any component, and lever handles or knobs shall still be operational after the test. After testing, the permanent deformation for lever handles or knobs measured at the reference point (75 ± 2) mm from the axis of rotation shall not increase by more than 2 mm. 5.5 Free play and safety 5.5.1 Requirement for free play The maximum total movement measured in accordance with 7.3.3 shall not exceed 10 mm for category of use grades 1 and 2, and 6 mm for category of use grades 3 and 4, for lock or latch furniture. This requirement only applies to lever handles and knobs that will not be driven during the endurance test. 5.5.2 Safety requirements When the lock or latch furniture is fitted to the test block there shall be no sharp edges that can cause injury. NOTE This requirement should typically be satisfied by edges that are broken by a chamfer of 0,5 mm maximum × 45° or by a radius of 0,5 mm minimum. In the area of rotation of the lever handle or knob, the head of any visible fastening element shall be level with or below the surface of the backplate or rose after fitting. However, raised head screws may stand proud of the furniture plate by the domed height of the screw head. SIST EN 1906:2012

6.1 Test sequence Examine samples before starting the tests to ensure completeness and compliance with the manufacturer's packaging statements and to identify possible damage. After checking the spindle and fastening elements (see 5.2), a half set of lock or latch furniture shall be fitted to a test block as specified in 6.2.1.1 and shall conform to 7.3.12.
