Overview

EN 1906:2012 is a CEN European Standard for building hardware - specifically lever handles and knob furniture that operate a latch or lock. It defines the requirements and test methods for mechanical performance, durability and safety of sprung and unsprung lever handles, knobs, push pads and similar devices when fitted with backplates or roses. EN 1906:2012 supersedes the 2010 edition and includes classifications, test sequences and normative annexes for special security and fire/smoke applications.

Key topics and technical requirements

• Classification & coding system - product grading by category of use, durability, door mass, fire resistance, safety, corrosion resistance, security and type of operation. Manufacturers declare the classification.
• Mechanical tests - specified test methods for:
  • Spindle and fastening elements (strength and check)
  • Operating torques and rotational strength
  • Permissible free play and user safety
  • Free angular movement and misalignment
  • Torque of return mechanism (sprung/unsprung behaviour)
  • Axial/static strength of lock or latch furniture and fixing
  • Durability (endurance) testing and repeat tests
• Corrosion resistance - tests and requirements for assessing finish and long‑term exposure performance.
• Special requirements (Annexes):
  • Annex A - additional security lock furniture requirements for burglary‑resistant doors (security grades 0–4)
  • Annex C - additional requirements and tests for use on smoke control and fire resistant doors (fire grades A–D)
• Marking and documentation - requirements for declared performance and test reports; conformity is based on meeting the table of main test parameters.

Practical applications

• Ensures consistent, measurable performance for door furniture used in residential, commercial and institutional buildings.
• Used to verify product durability, user safety and compatibility with fire/smoke door assemblies.
• Supports procurement specifications, product certification and manufacturer quality control.

Who should use EN 1906:2012

• Hardware manufacturers and product designers (design verification and declaration)
• Test laboratories and conformity assessment bodies (test methods and acceptance criteria)
• Specifiers, architects and building compliance officers (selection and performance verification)
• Installers and facility managers (ensuring appropriate grade for application)

Related standards

• EN 1154 (controlled door closing devices)
• EN 1634 series (fire resistance and smoke control tests)
• EN 314-2, EN 636 (relevant timber/plywood references)
• Other CEN/CENELEC building hardware standards

Compliance with EN 1906:2012 helps manufacturers and specifiers demonstrate that lever handles and knob furniture meet robust durability, safety, corrosion and fire/smoke performance expectations required for modern buildings.

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
