The European Federation of Associations of Locks & Builders Hardware Manufacturers


Construction hardware products are covered by CEN/TC33’s Working Group 4 (WG4).

Concerning the number of products covered and the number of standards to be on the list, WG4 is by far the biggest Working Group of CEN/TC33.

The Convenor of WG4 is Mr. Inge Lidén, a former Senior Manager from Assa-Abloy, Sweden. The secretariat is held by Ms. Lina Nordfors from SAS. The Convenorship of WG4 is supported by ARGE.  

Delegates in WG4 are the WG4 Task Group (TG) Convenors and experts nominated by national Standardisation Bodies. WG4 reports to TC33 and directly to the Commission Services or the HAS Consultants. WG4 usually meets 2 to 3 times a year, usually on 1 and 1/2-days meetings.

The last meeting of TC33/WG4 took place on March 20st, 2019.

The ARGE Chairman, Hans Weissenboeck is a member of WG4. Also several members of ARGE’s Executive team are members of WG4.
