Introduction This European Standard has been developed in response to demand throughout Europe aimed to ensure that locking systems manufactured in compliance with this standard will offer unattended bicycles a high, practical level of security. The tests have been designed and evaluated in practical tests by experts in the lock industry and consideration has been given to the latest techniques employed by professional cycle-thieves whose methods are constantly changing. The scope has been limited to security and durability requirements and, to some extent, the safety of the rider.

4.1 A cycle lock shall be so designed that when it is mounted according to the manufacturer’s instructions and locked, it shall fulfil all of the following requirements: a) cycle cannot be either ridden or pushed along in a normal way and the rotation of at least one wheel is prevented, and b) it is not possible to remove the lock by detaching a part of the cycle that is easy to detach and attach (e.g. a wheel or a seat-post), and c) it is not possible to remove or unlock it by deforming a part of the cycle (e.g. the front fork or the seat-stays) unless such deformation prevents the future normal use of the cycle. 4.2 For safety reasons, it shall not be possible for a permanently-mounted cycle lock or for a removable cycle lock, when mounted according to the manufacturer’s instructions, to interfere with the normal and safe use of the cycle. 4.3 For the requirements in clauses 4.3.1 to 4.3.5 deviations from the requirements are permitted if the same level of security can be achieved with other solutions. The assessment of any other such solutions shall be presented in the test report. 4.3.1 The key mechanism shall have at least five active detainers.
4.3.2 The key must be provided with at least three different depths of incision. 4.3.3 Only 60 % of the number of blocking elements shall be permitted to have the same incision. When the 60 % value does not result in a whole number, the immediately lower whole number shall apply 4.3.4 Not more than two equal, adjacent blocking elements shall be permitted. 4.3.5 The lock shall have a minimum number of practical effective differs (n), thus: a) for key- operated locks:
2 500 with a minimum of 1 000 per keyway
b) for combination locks:
9 000 c) for key-operated electronic locks:
50 000
d) for electronic locks operated by a remote device: 100 000. After each operation, the receiver shall require a new code, generated in a random pattern, in order to operate again. 4.4 Combination locks and electronic locks shall be so designed that it is not possible to determine the correct code by visually inspecting external scratches or marks after 500 times of opening and closing the lock. 4.5 Cycle locks shall be so designed that it is not possible to determine the correct code by visual inspection through the key-hole or other openings. 4.6 All locks except combination locks shall be delivered with at least two, but not more than four, keys or remote devices. 4.7 A permanently-mounted key-operated cycle lock shall be so designed that the locking is positive, i.e. the key shall not be removable from the lock until the blocking element of the shackle is in the blocked and locked position. 4.8 Electronic locks shall have a function that makes the lock capable of preventing opening by random or systematic generation and transmission of codes. An example of such a function is a time-delay function that blocks reception of further codes for a certain time after each reception of an incorrect code.

± 2 % Mass/weight

5.2.3 Examination prior to tests Prior to all tests the test personnel shall have the opportunity to examine the design of an assembled lock, an unassembled lock, technical drawings and specifications. 6 Specific requirements and test methods 6.1 Maximum operational unlocking torque 6.1.1 Requirement When tested by the method described in 6.1.2 the lock shall be unlocked at a torque not exceeding 1 Nm ± 0,1 Nm. 6.1.2 Test method Insert the correct key fully in the lock when it is in the locked position and gradually apply a torque to the key, turning it in the direction of unlocking. Record the maximum torque value needed in order to unlock the lock. 6.2 Non-interpassing of keys with just one interval effective differ 6.2.1 Requirement When tested by the method described in 6.2.2 it shall not be possible to operate the lock with the two keys differing from the correct key by one interval in the first detainer (the detainer closest to the head of the key). 6.2.2 Test method Insert the next closest key fully in the lock when it is in the locked position and gradually apply a torque to the key, turning it in the direction of unlocking. Increase the torque until a torque of 1,5 Nm ±
0,1 Nm is applied.
6.3.2
Test method Insert the correct key fully in the lock, blocked from rotation, and apply a torque of at least 2 Nm. 6.4 Durability 6.4.1 Requirement When tested by the method described in 6.4.2 the lock shall retain its normal function. 6.4.2 Test method Open and close the lock 5 000 times with the correct key or combination. Withdraw and insert any key after each locking. 6.5 Strength 6.5.1 General If a lock is of a type that should be subjected to a certain type of test, but is designed in such a way that it is impossible to apply the particular test, the lock shall be exempted from that test. Such an exemption shall be stated in the test report. Strength tests shall, unless otherwise stated, be performed only with directions and positions of forces that can be used in practice during the theft of a cycle. Of these directions and positions, those which the test engineer considers most likely to open the lock shall be used. 6.5.2 Requirement When tested by the methods described in 6.5.3, 6.5.4, 6.5.5, 6.5.6, and 6.5.7 the lock shall not break. When tested by the method described in 6.5.8, the essential part of the locking mechanism shall not completely detach from the lock. 6.5.3 Tensile strength – Test method 6.5.3.1 General Permanently mounted cycle locks with a maximum inner dimension less than 150 mm shall not be subjected to the tests in 6.5.3.2. 6.5.3.2 U-shackle locks 6.5.3.2.1 Tensile strength in the direction of opening Secure the body of the lock in a mounting device and ensure that the mounting device does not affect the test result. Gradually apply a force F, as shown in Figure 1, to the lock in the opening direction until the lock breaks or until a force of 30 kN is achi
