DIN EN 1303
specifies requirements and test methods for locking cylinders and locks. Properties tested include strength, closure security, durability and corrosion resistance. The properties present for the locking cylinders are expressed by an eight-digit classification key. In detail, the following properties are hidden behind the eight digits:
1. point: use class (1 class possible)
2. point: durability (3 classes possible)
A locking cylinder with a new original key must provide a certain number of locking cycles.
3. point: door dimensions (no classification)
no requirements for locking cylinders
4. point: fire resistance (2 classes possible)
Currently, the test criteria according to DIN EN 1634-1 apply, according to which the fire-retardant effect of the door must not be impaired by the locking cylinder.
5. point: operational safety (1 class possible)
no requirements for locking cylinders
6. point: corrosion resistance and temperature (4 classes possible)
Locking cylinders must meet the requirements of class 3 according to DIN EN 1670.
7. point: closure safety (6 classes possible)
- D min. no = minimum number of effective dissimilarities
- T min. no = minimum number of movable tumblers
- ED. steps max. no = equal depth steps maximum number
- ED. steps eo. = equal depth steps next to each other
8. point: attack resistance (3 classes possible)
- AD in min = drilling time in minutes
- GD-ZK in kN = total duration against tensile force in kN
- ZK in kN = tractive force in kN
standard for protective fittings and protective rosettes
building hardware-protective hardware-terms, dimensions, requirements and marking
- ES0 or 1 = low burglar resistance
- ES1 or 2 = moderate burglary resistance
- ES2 or 3 = strong burglar resistance
- ES3 or 4 = extreme burglar resistance
DIN EN 1154
This standard specifies the requirements for corresponding door closing devices and makes an important contribution to ensuring that a door closes reliably and in a controlled manner.
Many door closers and automatic door operators are adjustable. These are then provided with specifications such as EN 2 - 6.
DIN EN 12209
building hardware - locks and latches - mechanically operated locks and strike plates - requirements and test methods
This standard specifies requirements and test methods for the continuous functionality, strength, protective effect and mode of operation of mechanically operated locks and their striking plates.
1. point: usage category
2. point: continuous functional capability
3. point: door mass and closing force
4. point: suitability for use on fire and smoke doors (class 0 and class 1)
5. point: safety
6. point: corrosion resistance and temperature
7. point: protective effect and tapping resistance
8. point: door-related area of use
9. point: type of key operation and interlocking
10. point: type of spindle actuation
11. point: key identifier requirement
Handle sets of fire and smoke protection hardware are certified according to this standard.
the door handle sets are distinguished between:
- standard fittings
- anti-panic fittings
- exchangeable wires
All fittings for fire and smoke protection doors belong to the group of special fittings with building authority approval.
Manufacturer's marks for these are: DIN 18273 FS (fire protection set) or DIN 18273 RD (smoke protection set).
Door handle sets that comply with this standard are mechanically designed in such a way that, when used properly, the function and protective effect of the fitting are ensured even after a long period of use.
This also ultimately ensures the protective effect of the door closure on which it was mounted.
DIN 18273 applies to all types of lever handles in single or double-leaf design.
Key features are:
- The square pin used to operate the lever handle must be made of steel and basically have a cross-section of 9 x 9 mm.
- Fire door handle sets must withstand 200,000 opening and closing operations during endurance testing.
- Doors equipped with fire protection fittings must still be accessible after a fire.
mortise locks for rebated doors
defines terms, dimensions, requirements, tests and marking of mortise locks with latch and/or deadbolt, including mortise locks with self-locking function
mortise locks for tubular frame doors
specifies terms, dimensions, requirements, tests and marking of mortise locks with latch and/or deadbolt, including mortise locks with self-locking, suitable for installation in narrow stile doors
mortise locks for multipoint locking systems
DIN 18251-3 specifies the terms, dimensions, requirements, tests and marking of mortise locks as multipoint locks with latch and deadbolt including multipoint locks with self-locking. This DIN standard is only valid for multipoint locks which are intended for the installation of a profile cylinder according to DIN 18252. It does not apply to multipoint locks in escape doors.
DIN 18251 T 2 and T 3
serve as a basis for the security recommendation of the police and for the publication of the manufacturer directory of the Police Crime Prevention Commission (CPC) on tested and certified burglar-resistant products
