Corrosion resistance follows EN 1670, and for cylinders intended for fire or smoke doors, additional fire performance tests are conducted (see Annex A). Manufacturers may declare compliance with these additional requirements where applicable.
Buyers should verify that the chosen cylinders are suitable for their specific project requirements, ensuring long-term security, reliability, and compliance with European standards.
Guide to EN 1303:2015 - Cylinders for Locks Coding System
Buyer takeaway: The EN 1303 coding system lets you judge a cylinder’s durability, security level, and environmental suitability in seconds — instead of relying on marketing descriptions.
The EN 1303:2015 European Standard provides a comprehensive framework for assessing lock cylinders, covering aspects such as durability, fire resistance, and protection against attacks. Products are classified using an 8-digit performance code, with each digit corresponding to a specific attribute tested against standardized criteria. This clear coding system allows buyers and engineers to quickly compare lock cylinder performance and choose the solution that best meets their security and project requirements.
EN 1303:2015 –Digit 1 – Category of Use
The first digit indicates the category of use for the lock cylinder.
Grade 1: Suitable for situations where users are attentive and careful, and the risk of misuse is low. This makes it ideal for residential or low-risk applications where reliability and everyday security are important.
EN 1303:2015 – Digit 2 – Durability
Why this matters:
If you supply doors for public buildings, schools, hospitals, or any high-traffic facility, Durability Grade 6 is often mandatory. Choosing the correct grade helps prevent premature wear, reduces maintenance costs, and ensures long-term reliability for your clients.
| Durability Grade (Digit 2) | Test Cycles | Typical Applications / Notes |
|---|---|---|
| Grade 4 | 25,000 cycles | Designed for standard usage. Suitable for residential doors, private apartments, and other low-frequency operation environments. |
| Grade 5 | 50,000 cycles | For medium-frequency use. Commonly used in offices, schools, and general public buildings where doors are operated regularly. |
| Grade 6 | 100,000 cycles | Intended for high-frequency and intensive use. Ideal for large commercial buildings, hospitals, transport facilities, and industrial projects. |
Durability Tests – Standard Test Cycles
EN 1303:2015 specifies a strict durability testing procedure to verify that lock cylinders perform reliably throughout their rated lifespan.
During testing, the cylinder is operated with a new original key, completing repeated rotations in both clockwise and counterclockwise directions. Each cycle simulates normal use and includes a resistive torque of 0.15 ± 0.05 Nm to ensure proper operation of the cam and deadbolt.
Key points of the test:
- Cycle sequence: Insert key → rotate clockwise → withdraw key → insert key → rotate anticlockwise → withdraw key.
- Cycle speed: 5–12 cycles per minute.
- Torque verification: The cylinder must overcome the specified resistive torque during each rotation.
- Lubrication: Cylinders are lubricated according to the manufacturer’s instructions at the start of the test and after every 5,000 cycles (or as agreed with the testing lab).
- Alternative sequences: If the standard sequence cannot be applied, manufacturers may use an approved equivalent procedure.
- Acceptance criteria: After completing the rated number of cycles, the cylinder must operate smoothly with a new original key, with a maximum torque of 1.5 Nm.
This procedure ensures that cylinders meet their durability grade (Grade 4, 5, or 6) and are suitable for a wide range of projects, from residential doors to high-traffic commercial or industrial applications.
EN 1303:2015-Digit 3 – Door Mass
The third digit in the EN 1303:2015 code represents the door mass grade.
Grade 0: No specific door mass requirement. This means the lock cylinder can be used with doors of any standard weight, providing flexibility for a wide range of residential, commercial, and industrial applications.
EN 1303:2015 –Digit 4 – Fire / Smoke Door Suitability
Why this matters:
For fire doors and smoke-control doors, always select Grade B to meet legal and insurance requirements. Grade A is suitable where only smoke control is needed, and Grade 0 should be limited to standard internal doors without fire or smoke protection needs.
The fourth digit in the EN 1303:2015 code indicates the cylinder’s suitability for use on fire-resistant or smoke control doors. This ensures that the lock complies with safety regulations where fire or smoke protection is required.
Grades of suitability:
- Grade 0: Not approved for use on fire or smoke control door assemblies.
- Grade A: Approved for use on smoke control doors, offering protection in environments where smoke containment is required.
- Grade B: Approved for use on both fire-resistant and smoke control doors, ensuring compliance with fire safety standards and maximum protection.
Selecting a cylinder with the correct fire/smoke grade is essential for building compliance, safety, and insurance requirements. It ensures that doors maintain their fire-resistance and smoke-control performance while providing reliable locking functionality.
Fire / Smoke Door Suitability Detailed Tes
The fourth digit of EN 1303:2015 indicates whether a cylinder is suitable for use on fire-resistant or smoke control doors. Cylinders are classified into three grades based on fire and smoke performance:
Grade 0: Not approved for use on fire or smoke door assemblies.
Grade A: Suitable for use on smoke control doors. To meet this grade, cylinders must comply with one of the following:
- The door assembly incorporating the cylinder passes a smoke test according to EN 1634-3; or
- The cylinder parts that prevent smoke leakage are made of materials with a melting point of at least 300°C.
Grade B: Suitable for use on fire-resistant and smoke control doors. Cylinders in this grade must meet one of the following requirements:
- Be representative of their type and successfully pass a fire test according to EN 1634-1 or EN 1634-2, proving the cylinder’s effect on the fire resistance of the complete door assembly. After the test, operational functionality is not mandatory. Product information must include:
- Reference to the fire test report
- Type of door used for testing (e.g., wood, metal sheet)
- Reference to the fire test report
- The parts responsible for preventing fire spread must be made of materials with a melting point of at least 840°C.
Selecting the correct grade ensures that the cylinder complies with fire and smoke safety standards, protects property and occupants, and meets regulatory requirements for both residential and commercial installations.
EN 1303:2015 –Digit 5 – Safety
EN 1303:2015 defines the safety level of a lock cylinder with a single grade:
- Grade 0: No specific safety requirements.
This means the cylinder does not include additional anti-manipulation features beyond standard mechanical operation. While all EN 1303 cylinders meet basic operational standards, projects requiring advanced protection (against picking, bumping, or unauthorized access) should consider higher-security solutions or TS 007-rated cylinders.
EN 1303:2015 –Digit 6 – Corrosion Resistance & Temperature
