This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by
17、July 2008, and conflicting national standards shall be withdrawn at the latest by July 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent r
18、ights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
19、Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. DIN EN 15496:2008-04 EN 15496:2008 (E) 5 Introduction This European Standard has been developed in response to demand throughout Europe
20、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 techniqu
21、es 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. DIN EN 15496:2008-04 EN 15496:2008 (E) 6 1 Scope This European Standard specifies performance requirements
22、 and describes test methods for strength, security, function and corrosion resistance of locks for cycles. It also covers certain aspects regarding the safety of the rider of the cycle on which the lock is mounted. This standard covers permanently-mounted cycle locks and removable locks. 2 Normative

26、 apply. 3.1 cable lock cable made of steel wire, in a single or spiral loop, with one end permanently attached to the lock housing 3.2 chain and lock combination chain with a detachable lock 3.3 chain lock chain combined with a padlock or U-shackle lock 3.4 combination lock lock that can be operated
27、 without a key and unlocked by moving parts of the lock in a certain pattern (combination of movements) 3.5 cycle any vehicle that has at least two wheels and is propelled solely or mainly by the muscular energy of the person on that vehicle, in particular by means of pedals 3.6 cycle lock device wh
28、ich, when locked, is intended to mechanically prevent the use of a bicycle DIN EN 15496:2008-04 EN 15496:2008 (E) 7 3.7 depth of incision depth of transverse notches on the length of a key 3.8 detainer part of the key mechanism of a locking mechanism which should first be moved by the key into a pre

32、 mechanism to lock/unlock the lock 3.16 padlock independent locking device comprising a housing, a key mechanism, a locking mechanism, and a shackle 3.17 plug part of the key-mechanism that can be moved when the proper key is used 3.18 permanently-mounted cycle lock cycle lock that forms one unit (e
33、xcluding accessories and keys), which is mounted on a cycle and that can be considered as a permanent part of that cycle. A permanently-mounted lock can also be equipped with accessories such as chains or cables which can be locked with the same locking unit as that of the permanently-mounted lock N
34、OTE One of the most common types of lock of this type is the so-called frame lock. 3.19 practical effective differ difference between key mechanisms of similar design, achieved only by the movable detainers, which allow each key mechanism to be operated only by its own key. The number of practical e
35、ffective differs is equal to DIN EN 15496:2008-04 EN 15496:2008 (E) 8 the number of theoretical differs after deduction of the differs suppressed by the manufacturer due to technical constraints and deduction of the differs suppressed by requirements in this standard (see clause 4) 3.20 removable cy
36、cle lock cycle lock that consists of one or more than one unit and that can be used for locking a cycle but that cannot be considered as a permanent part of that cycle since it is detachable without the use of any tools other than a key. Removable locks are often used for the connection of a cycle t

43、(E) 10 4.1 A cycle lock shall be so designed that when it is mounted according to the manufacturers 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)
44、 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 futu
45、re 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 manufacturers instructions, to interfere with the normal and safe use of the cycle. 4.3 For the requirements in clauses 4.3.1
46、 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 prov
47、ided 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 blocki
48、ng 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
49、 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 e
