BS EN12209 construction hardware machinery operating locks, latches and locking plates

EN 12209 uses an 11-digit coding system to classify mechanically operated locks, latches and locking plates. The basis of this standard is a comprehensive classification system for evaluating a wide range of products needed to meet the diverse requirements of the European market.

The features evaluated include normal use (and abuse) force, long-term durability, fire/smoke resistance, corrosion resistance, temperature resistance, and safety, including maneuverability and physical properties.

1.Category of use


Three grades are identified:

    Grade 1 : Low frequency of use by people with a high incentive to exercise care and a small chance of misuse.E.g.Internal residential doors

Fire Doors-Locks


The UK construction Products Regulations require locks for use on fire doors to be safe and durable. British/European standards BS EN 12209 is the recognised way of demonstrating compliance and requires that an official Notified Body proves both the product and the manufaturer's factory product controls are satisfactory before CE marking can be applied. It is recommended that locks fitted to Fire doors should be CE marked.


CE Marking


The CE mark is the easiest and safest way to provide hardware that complies with the latest UK building product regulations to use fire, smoke and escape doors.


BS8300 & Approved Document "M" of the Building Regulations


These documents recommend that locks should have a backset of at least 55 mm and a center of at least 72 mm. A Lock with keyway above the cylinder are also very suitable.
