How to choose qualified EN1303 cylinder for your project needs?
Like Hinge,Mortise lock,Lever handle,there is also a coding system for BS EN1303 Cylinder.Let’s find out what does each digit means.
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 : 100000 Cycles
3. Door mass
One category is identified.
Grade 0 : No requirement
4. Fire resistance
Two grades are identified:
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. 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 corrosion resistance: resistance to -20/+80C temperature extremes.
No distinction is made between the inside and the outside of either the cylinder and/or the door. On completion of the test, the cylinder must operate
7. Key related security
Six grades are identified and the principal requirements are summarized as below :
8. Attack resistance
Three grades are identified and the principle requirements are summarized as below:
In next share,we will introduce some normally seen Key management function like "Keyed to Differ","Key Alike","Common Entrance","Master key/Grand Master key/Great Grand master key","Construction key".
