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
Grade 2 : Medium frequency of use by people with some incentive to exercise care but where there is some chance of misuse.E.g.Internal office doors.
Grade 3 : High frequency of use by public or others with little incentive to exercise care and with a high change of misuse.E.g.Public doors.
2.Durability
Twelve grades are identified with minimum figures for deadbolt and snib operation, and latch bolt operation with and without side load, as show. The side load is applied to the latch bolt when it is being withdrawn.

D&D CE mark European Mortise Lock Successfully tested for conformity to all the requirements of BS EN 12209, 11 Classification:3X910G3BC20
BS EN 1634 Part 1: 2000
The European Fire Safety Satandard for determining the fire resistance of door and shutter assemblies including hardware designed for installations within openings incorporated in vertical seprating elements (doorsets).
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.
