(1) DOOR MASS No requirement. - EN 12320 – padlocks and padlock fittings EN 12320 classifies padlocks and padlock fittings by using an 8 digit coding system. Each digit refers to a particular feature of the product measured against the standard’s performance requirements. (0/1) DURABILITY Grade 0: no requirements. Grade 1: 10,000 cycles. (0-5) CORROSION RESISTANCE The padlock shall be exposed to a neutral salt spray test in accordance with EN 1670. On completion of the test, the cylinder must operate using a maximum 2.5Nm torque on the key. Grade 0: no defined corrosion resistance; Grade 1: 24h +1h/-0 h Grade 2: 48h +1h/-0 h Grade 3: 96h +1h/-0 h Grade 4: 240h +1h/-0 h Grade 5: 480h +1h/-0 h ATTACK RESISTANCE (see table opposite) Six grades of resistance against drilling and mechanical attack are identified in accordance.

When it comes to padlocks and security ratings, CEN have come together to provide a standardised approach for categorising and comparing padlocks across different manufacturers. There are a total of 6 levels to the CEN rating for padlocks from 1 to 6. The criteria for each CEN assessment level is taken from the EN 12320 security criteria as shown in the table above.
