EN 12209 classifies mechanically operated locks, latches and locking plates using an 11 digit coding system. Fundamental to this standard is a comprehensive classification system for assessing the wide range of products needed to satisfy the diverse requirements of the European market.
Features assessed include normal use (and abuse) forces, long-term durability, fire/smoke resistance, corrosion and temperature resistance and security, both manipulative and physical.
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 The side load is applied to the latch bolt when it is being withdrawn.
3.Door mass and Closing Force
Nine grades are identified with maximum figure for closing force at various door masses as shown. Note :losing force is form a standing. Star :i.e.fully extended latch bolt in contact with striking plate at star of test .
| Maximun closing | Up to 100kg | Door mass up to 200kg | Above 200kg |
| 15N | grade 7 | grade 8 | grade 9 |
| 25N | grade 4 | grade 5 | grade 6 |
| 50N | grade 1 | grade 2 | grade 3 |
4.Fire resistance
Two grade are identified :
Grade 0 : Not approved for use on fire/smke door assemblies
Grade 1 : Suitable for use on fire/smoke door assemblies tested to BS EN 1634-1 etc.
5.Safety
No requirement, but note : a lock or latch conforming to this standard can, at the same time, also be part of an exit device conforming to BS EN 179 or BS EN 1125.
6.Corrosion resistance
Eight grade are identified with neutral salt-spray (NSS)corrosion resistance grades from BS EN 1670:1988, with and without Temperaturere resistance as shown :
| Corrision resistance (NSS) | Temperature resistance | |
| No requirement | -20c to +80C | |
| 240 hours | grade D:very high corrosion resistance | grade G: very high corrosion resistance |
| 96 hours | grade C:high corrosion resistance | grade F: high corrosion resistance |
| 48 hours | grade B: moderate corrosion resistance | grade E: moderate corrosion resistance |
| 24 hours | grade A: low corrosion resistance | |
| No requirement | grade O: no defined corrosion resistance | |
7. Security and drill resistance
Seven grades are identified with minimum figures for requirements relating to physical attack, with or without drilling of the lockcase, as shown:
8. Field of door application.
9.Type of Key operation and locking.
Nine grades are identified for differing types of key operation, The grading determines how the lock is assessed foe deadlocking requirement as shown. In addition, there is a maximum key torque operating requirement of 1.5 Nm and a minimum key strength requirement of 2.5 Nm .
Grade 0 : Not applicable;
Grade A : Cylinder lock or latch; manually locking;
Grade B : Cylinder lock or latch; automatically Locking;
Grade C : Cylinder lock or latch; manually locking with intermediate locking;
Grade D : Lever lock or latch; manually locking;
Grade E : Lever lock or latch; automatically locking;
Grade F : Lever lock or latch; manually locking with intermediate locking;
Grade H : Lock or latch without key opreation;manually locking;
Grade G : Lock without key operation; automatically locking.
10. Type of spindle operation
Five grades are identified
Grade 0 : Lock without follower
Grade 1 : Lock with sprung lever or knob
Grade 2 : Lock with light unsprung leverg.
Grade 3 : Lock with heavy unsprung lever
Grade 4 : Lock with manufacturer's own specification furniture
11. Key identification
Nine grades are identified relating to the number of differs and levers.Grades to a latch with no locking action.
