Inquire

1. Category of use

One category is identified.

Grade 1: For use by people with a high incentive to exercise care and with a small chance of mis-use.

2. Durability

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

Grade 4 : 25 000 Cycles

Grade 5 : 50 000 Cycles

Grade 6 : 100 000 Cycles

3. Door mass

One grade is identified:

Grade 0 : No requirement

4. Fire resistance

Two grades are identified:

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

Grade 1 : Suitable for fire/smoke door accessories subject to satisfactory assessment of the contribution of the cylinder to the fire resistance of the specified fire/smoke door assemblies. Such assessment is beyond the scope of this European standard (see EN 1634-1).box 4), it must be possible to demonstrate compliance with the Essential Requirements of the Construction Products(Amendments)Regulations.

5. Safety

One grade is identified:

Grade 0 : No requirement

6. Corrosion and Temperature Resistance

Four grades are identified according to EN 1670:

Grade 0 : No corrosion or temperature resistance requirements

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

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

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

There is no difference between the inside and outside of the cylinder and/or door.After the test is completed, the cylinder must operate.

7. Key related security

The main requirements of the six grades are summarized in Table 1 below:

	Grade
	1	2	3	4	5	6
Minimum number of effective differs	100	300	15,000	30,000	30,000	100,000
Minimum number of movaable levers, pins, discs etc	2	3	5	5	6	6
Minimum number of movaable levers, pins, discs etc	Yes	Yes	No	No	No	No
Coding on key should disclose close combination	2.5Nm	5Nm	15Nm	15Nm	15Nm	15Nm

8. Attack resistance

The main requirements of the three grades are summarized in Table 2 below:

Resistance to drilling (nett drilling time )	Grade
	0	1	2
	-	3/5	5/10 mins
Resistance to chisel attack (number of defined belows)	-	30	40
Resistance to twisting attack (number of defined twists)	-	20	30
Resistance to plug/cylinder extraction (pull load)	-	15N	15kN
Torque resistance of plug/cylinder	-	20Nm	30Nm

BS EN1303 Lock Cylinder-D and D Hardware

Keyed To Differ(KD)

Cylinders to differ are all operated by individual keys all different to each other. Each lock cylinder has a corresponding key.

Keyed to Differ

Keyed Alike Suites(KA)

In the same keying arrangement, all cylinders are operated by the same key. This gives an arrangement where one key can open a group of locks. Not to be confused with the primary key suite (see below). Cylinders can also be similar to keyed euro profile, oval and rim cylinders.

Keyed Alike Suites-D and D Hardware

Common Entrance Suite

Each individual key is opened its own lock and the common entrance.

Master key Suites(MK)

A group of cylinders, each equipped with a separate service key, is also operated by one special key called the master key. The keyed alike suites groups can also be merged into any master key.

Construction Key(CK)

Construction key can operate the cylinder during construction period.After construction is ended up，Master Key can insert the cylinderand change the pin combination.The construction key can not openthe same cylinder lock any more.

Grand Mater Key Suites(GMK)

Grand master key suite is called a sub suite.In these cases, all cylinders irrespective of their sub suite, are controlled by a key as the grand master key.
