EN 1303

EN 1303 is a security rating . In Europe, the European Committee for Standardization (Comite European de Normalisation) (CEN) provides rating and testing systems for security devices.


Code Number

An 8-digit code is used to state the level of compliance. Each digit corresponds to a category and how the lock cylinder responded to testing.[1]

Digit 1 - Category of use

One category is identified:

  • Grade 1: Keys shall resist a torque of 2.5Nm and still be usable. This is for use by people with a high incentive to exercise care and with a small chance of misuse.

Digit 2 – Durability

Three grades of durability classify cylinders as either grade 4, 5, or 6 based on 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

  • Grade 0 - No requirement.

Digit 4 – Fire resistance

Cylinders are classified as either grade 0 , A or B.

  • Grade 0: Not approved for use on fire/smoke door assemblies.
  • Grade A: Cylinders shall be subjected to a smoke test in accordance with EN 1634-3 or materials for the parts of the cylinder responsible for preventing any leakage of smoke shall have a melting point not less than 840 °C.
  • Grade B: Cylinders shall be fire tested in accordance with current fire test requirements of EN 1634-1 or EN 1634-2 or materials for the parts of the cylinder responsible for preventing the spread of fire shall have a melting point not less than 300 °C.

Digit 5 – Safety

  • Grade 0 - No requirement.

Digit 6 – Corrosion and temperature resistance

Cylinders are classified as either grade 0, A, B or C:

  • Grade 0: No corrosion or temperature requirement.
  • Grade A: High corrosion resistance, no temperature requirement.
  • Grade B: No corrosion requirement, temperature requirement between - 25 °C and + 65 °C.
  • Grade C: high corrosion resistance, temperature requirement between - 25 °C and + 65 °C.

Note: 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 using a maximum 1.5 Nm torque on the key at both - 25 °C and + 65 °C.

Digit 7 – Key Security

Cylinders are classified in grades 1 to 6, where 6 is the highest. The grade of security can differ from one side of a double cylinder to the other. The table below provides a summary of the main security requirements.

Requirement Unit Grades
1 2 3 4 5 6
Min number of effective differs Number 100 300 15,000 30,000 30,000 100,000
Min number of movable detainers Number 2 3 5 5 6 6
Max number of idential % 100 70 60 60 60 50
Max number of identical adjacent steps Number - 2 2 2 2 2
Direct coding on key - - - No No No No
Operation of security mechanism (interpassing) torque Nm 1.5 1.5 1.5 1.5 1.5 1.5
Torque resistance of plug/cylinder Nm 2.5 5 15 15 15 15

Digit 8 – Attack resistance

Cylinders are classified grades 0 to D where D is the highest. The table below provides a summary of the main requirements.

Requirement Unit Grades
0 A B C D
Resistance to drilling (net drilling time) Minutes - 3 to 5 5 to 10 3 to 5 5 to 10
Resistance to chisel attack (number of defined blows) Number - 40 40 30 40
Resistance to twisting attack (number of defined twists) Number - 20 30 20 30
Resistance to plug/cylinder extraction (force) kN - - - 10 15
minutes - - - 5 to 15 5 to 15
Torque resistance of plug/cylinder (torque) Nm - 20 30 20 30
