Lock The Door
MEKATRON covers all what is required on a door to make it operational, functional as per design intent, safe and secure as per latest standards and building codes.
Cylinders
BS EN 1303 Cylinder locks
The European standard applies to cylinders intended for use on locks in buildings. It identifies just one grade for category of use, three grades of durability, two grades of fire resistance, four grades of corrosion and temperature resistance, six grades of key related security based on design requirements, and three grades of attack resistance based on mechanical performance tests. The suitability of cylinders for use on fire/smoke door assemblies, additional functions within the design of the cylinder not covered by the European standard.This is particularly important when the operation of such additional functions is safety related.
Classification
BS EN 1303: 2005 classifies cylinders for locks using an 8 digit coding system
Digit 1 - Category of use
One category is identified:
Grade1: 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 cycles Grade 5: 50 000 cycles Grade 6: 100 000 cycles
Digit 3 Door mass
No requirement.
Digit 4 - Fire resistance
Two grades are identified: –
– 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 etGrade 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.c.
Digit 5 Safety
No requirement.
Digit 6 Corrosion 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
Digit 7 - Key related security
Six grades are identified and the principal requirements are summarised in Table 1 below:-
