15、2008 (E) 4 Foreword This document (EN 15496:2008) has been prepared by Technical Committee CEN/TC 333 “Cycles”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the lates
16、t by July 2008, and conflicting national standards shall be withdrawn at the latest by July 2008.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 pat
17、ent rights. 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, Irel
18、and, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. EN 15496:2008 (E) 5 Introduction This European Standard has been developed in response to demand throughout Europe aimed to ensure
19、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 p
20、rofessional 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. EN 15496:2008 (E) 6 1 Scope This European Standard specifies performance requirements and describes test methods for stren
21、gth, 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 references The following referenced

25、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 without a key and unlocked by moving
26、 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 which, when locked, is intended to mech

A key mechanism is also used as a synonym to “identification
30、number” (regarding electronic locks) and “combination code” (for combination locks) 3.14 lock housing part of the lock containing the key mechanism and blocking mechanism 3.15 locking mechanism part of the mechanism that is operated by the key mechanism to lock/unlock the lock 3.16 padlock independe
31、nt 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 (excluding accessories and keys), which is mounted on a cyc
32、le 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 NOTE One of the most common types of lock of this type is
33、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 effective differs is equal to EN 15496:2008 (E) 8 the numb
34、er 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 cycle lock cycle lock that consists of one or more than one unit and that can be
35、 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 to other cycles or to fixed objects such as a ground-anchor 3.21 shackle part o
36、f the lock which passes through and secures the lock fitting 3.22 u-shackle lock lock housing with a partially or totally detachable shackle in which the legs of the shackle may or may not be parallel to each other EN 15496:2008 (E) 9 4 General requirements NOTE In Table 1, a summary of the requirem

42、ocked, 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 whee
43、l 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
44、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 to 4.3.5 deviations from the requirements are permitted if the same level of security can be achieved with other sol
45、utions. 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 pe
46、rmitted 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:
47、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,
48、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 d
