BS EN 1303: 2005 – Cylinder Locks

 

 

BS EN 1303: 2005 classifies cylinders for locks using an 8 digit coding system. Each digit refers to a particular feature of the product measured against the standard's performance requirements.

 

Digit 1: Category of Use

 

One category is identified:

 

Grade 1: Keys shall resist a torque of 2.5Nm and still be usable.

 

Digit 2: Durability

 

Three grades are identified according to the number of test cycles achieved:

 

Grade 4: 25,000 test cycles.

Grade 5: 50,000 test cycles.

Grade 6: 100,000 test cycles.

 

Digit 3: Door Mass

 

No requirement.

 

Digit 4: Fire Resistance

 

Two grades are identified as follows:

 

Grade 0: Not suitable for fire/smoke resistant door assemblies

Grade 1: Suitable for fire/smoke resistant door assemblies subject to satisfactory assessment of the

                contribution of the cylinder to the fire resistance of the specified fire/smoke door assemblies.

 

Digit 5: Safety

 

No requirement.

 

Digit 6: Corrosion and Temperature Resistance

 

Four grades are identified as follows:

 

Grade 0: No corrosion or temperature resistance requirements

Grade A: BS EN 1670 Grade 3 corrosion resistance (96 hours NSS): no temperature resistance requirement

Grade B: No corrosion resistance requirement: resistance to -20/+80°C temperature extremes

Grade C: BS EN 1670 Grade 3 corrosion resistance: resistance to -20/+80°C temperature extremes

 

Note 1: No distinction is made between the inside and the outside of either the cylinder and/or the door.

Note 2: On completion of the test, the cylinder must operate using a maximum 1.5 Nm torque on the key.

 

Digit 7: Key Related Security

 

Six grades are identified and the principal requirements are summarized below:

 

 

 

 

 

 

 

 

 

 

 

 

 

Digit 8: Attack Resistance

 

Three grades are identified and the principal requirements are summarized below:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Example

 

 

 

 

The above marking denotes a cylinder meeting the required category of use Grade 1, durability Grade 6 (100 000 cycles), no requirement for door mass, no fire resistance or safety in use requirement, having Grade A

corrosion resistance, Grade 4 key related security and Grade 1 attack resistance.

 

CE Mark

 

BS EN 1303 has not been designated as a harmonised product standard under the Construction Products Directive and therefore CE marking of cylinders to this standard is NOT permitted.

 

 

 

 

 

 

 

 

 

 

Selecting Cylinder Length

 

There are two reasons for carefully selecting cylinder lengths:

 

1.To limit the amount of cylinder projecting from the face of the door which can be susceptible to attack

2.For aesthetic reasons and to avoid the risk of hitting the cylinder with the hand when using lever handles

 

Factors to consider in choosing the correct cylinder length:

 

•Door thickness

•Hardware thickness

•Lock mounting position

•Lock fitted on the center line (A)

•Lock fitted off center (B)

 

Keying System

 

Voset offer a number of different keying arrangements to

ensure your system is tailored to your requirements.

 

Individually Keyed (KD)

With an individually keyed system, each cylinder can be operated by its own unique individual key. (C)

 

Keyed Alike (KA)

This system allows a number of cylinders to be operated by one key. It is ideally suited to residential and commercial applications where minimal key control is required. (D)

 

Master Keyed (MK)

In a master key system, each cylinder is operated by its own unique individual key and can also be operated by one special key known as the master key. Keyed Alike and Common Entrance system can be incorporated into any master key system. (E)

 

Grand Master Keyed (GMK)

This is an extension of the master-keyed system where each lock has its own individual key and the locks are divided into 2 or more groups. Each lock group is operated by a master-key and the entire system is operated by one grand master-key. This is ideally utilized in complex commercial systems. (F)
