VOSET locks series are manufactured from the best quality materials to achieve exceptional durability for extreme reliability, provides maximum security and functionality and can withstand the constant use and abuse.

 

VOSET offers a wide variety of design and sizes that is suitable for architectural specification and for both commercial and residential applications

 

BS EN 12209 : 2003 – Mechanically Operated Locks, Latches and Locking Plates

 

 

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.

 

BS EN 12209 classifies mechanically operated locks, latches and locking plates using an 11 digit coding

system. The system is comprehensive but it has led to the use of letters (rather than numbers) in certain boxes, since there can only be one digit in each classification box.

 

Digit 1: Category of Use

 

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 chance of misuse, e.g. public doors

 

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 The side load is applied to the latch bolt when it is being withdrawn.

 

 

 

 

 

 

 

 

Digit 3: Door Mass and Closing Force

 

Nine grades are identified with maximum 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.

 

 

 

 

 

 

 

 

 

Digit 4: Fire Resistance

 

Grade 0: Not approved for use on fire/smoke door assemblies

Grade 1: Suitable for use on fire/smoke door assemblies tested to 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 30 minutes 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/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 Regulations.

             It is recommended that the product should bear the CE mark.

 

Digit 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 EN 179 or EN 1125.

 

Digit 6: Corrosion Resistance

 

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

 

 

 

 

 

 

 

 

 

 

 

Digit 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:

 

 

 

 

 

 

 

 

 

 

Digit 8: Field od Door Application

 

Fifteen grades are identified for differing applications – hinged or sliding doors with rim or mortise locks with either keyless egress from inside or key locking from both sides. The grading determines which application is appropriate. In addition, 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.

 

Digit 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 for 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 G: Lock or latch without key operation; manually locking.

Grade H: Lock without key operation; automatically locking.

 

Digit 10: Type of Spindle Operation

 

Five grades are identified:

 

Grade 0: Lock without follower.

Grade A: Lock with sprung lever or knob.

Grade B: Lock with light unsprung lever.

Grade C: Lock with heavy unsprung lever.

Grade D: Lock with manufacturer’s own specification furniture

 

Digit 11: Key Identification

 

Nine grades are identified relating to the number of differs and levers.

Grade 0 relates to a latch with no locking action:

 

 

 

 

 

 

 

 

 

 

 

Example:

 

 

 

 

The above indicates a mechanically operated lock and locking plate intended for use in situations where there is an incentive to exercise care; that will withstand a durability of 200,000 cycles with a 10N side load on the latch bolt on a door of up to 200 kg in mass; that will close with a maximum force of 25N; that is suitable for use on a fire/smoke resisting door; that has no safety requirement; that has moderate corrosion resistance over a  temperature range of -20°C to +80°C; that has high security and drill resistance; that is a lever mortise lock with manual locking; that is suitable for unsprung furniture; and that has five detaining elements with a minimum of 10,000 differs.

 

CE Mark:

 

Mechanically operated locks and latches intended for use on fire/smoke control doors within the European Economic Area are covered by a Construction Products Directive mandate issued by the European Commission. Consequently, this standard is regarded as “harmonised” and compliance with it, supported by suitable evidence, allows for the application of the CE mark.
