BS EN 12209 Building Hardware –Mechanically Operated Locks, Latch and Locking Plates

1.Category of use

Four 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 The side load is applied to the latch bolt when it is being withdrawn.
 

No of operations	Incesting Side Load
	grade C	grade H	grade M	grade S	grade X
	grade B	grade G	grade L	grade R	grade W
	grade A	grade F

 
3.Door mass  

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.

Note 1. A grade 1 classification means only that the lock has been designed for use on fire/smoke control doors; the actual fire performance achieved(e.g.fire integrity of 30minutes on a partially glazed timber door etc.)will be contained in a separate fire test report.

Note 2. Where a product is intended for fire/somke door use (i.e.a."1" in box 4 ), it must be possible to demonstrate compliance with the Essential Requirements of the Construction Products (Amendments)Regulation. It is recommended that the product should bear the CE mark(see section on CE marking) .
 

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	grade G
96 hours	grade C	grade F
48 hours	grade B	grade E
24 hours	grade A
No requirement	grade O

8. Field of door application.

Fifteen grades are identified for differing applications-hinged or sliding doors with rim or mortice locks with either keyless egress from inside or key locking from both sides.The grading determine which application is apporopriate.in addition, there there is a requirement that lock/latch should not be removable from outside or, for grades K to R, from inside using "standard" tools. Grades H and P require support for the lockcase when installed.

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.

No of differs	No of levers
									grade H
					grade F			grade G
				grade D			grade E
			grade B			grade C
		grade A
	grade 0

BS EN 1634 Part 1: 2000

Is 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

CE marking is the easiest and safest route to providing compliance with the latest UK Construction Products Regulations for hardware used on fire, smoke and escape doors.

 

All our products strictly according to international Standard, such as the ANSI, BS EN/CE, UL, BHMA standard.
