BS EN12209 Building Hardware-mechanically operated locks, latches and locking plates.

BS EN 1906 classifies door furniture by using an 8 digit coding system. A similar classification applies to all building Hardware product standard so that complemantry items of hardware can be specified to, for instance, a common level of corrosion resistance, category of use, etc. Each digit refers to a particular feature of the product measure against the standard's performance requirements.


1. Category of Use

Four grades are identified:


Grade 1

Low frequency of use by people with ahigh incentive to exercise care and a small chance of misuse, Eg: 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, Eg: Internal office doors

Grade 3

High frequency of use by public or others with little incentive to exercise care and with a high chance of misuse, Eg: 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latch bolt operation with and without side load,as shown.The side load is applied to the latch bolt when it is being withdrawn.


Increasing 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 minimum figures for closing force at various door masses as shown.Note: closing force is from a standing start : i.e. fully extended latch bolt in contact with striking plate at start of test.


Maximum Closing Force

Door mass
up to 100kg

Door mass
up to 200 kg

4. Fire resistance

Four grades are identified:


Grade 0

Not approved for use on fire/door assemblies

Grade 1

suitable for use on fire/smoke door assemblies tested to BS EN1634-1 etc.

Note1

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

Note2

where a product is intended for fire/smoke 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) Regulations.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 he same time,also be part of an exit device conforming to BS EN 179 or BS EN 1125.

6. Corrosion resistance

Eight grades are identified with neutral salt-spray (NSS) corrosion resistance grades from BS EN 1670:1998, with and without temperature resistance as shown :-

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, froem inside using "standard" tools.Grades H and P require support for the lockcase when installed.


TOP

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 .

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.

BS8300 & Approved Document "M" of the Building Regulations

These documents recommend that locks should have a minimum of a 55mm backset and that the centres should be a minimum of a 72mm. Locks with keyways above the cylinder are also suitable.
