17、 organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Noway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This European St
18、andard is one of a series of European Standards dedicated to building hardware products. Test methods are specified in detail to ensure reproducibility at any test establishment within Europe, and acceptance criteria are defined objectively to ensure consistency of assessment. No human intervention
19、tests are included. Normative annexes (A, B and C) and informative annex (D) to this European Standard are indicated in the contents. Work is in progress to support the implementation of the European standards by evidence which demonstrates the conformity of the products to the technical requirement
20、s set out in those standards. In order not to delay the publication of the present standard, those conformity assessment criteria related to door and window bolts will be published separately. They will be incorporated in this standard when next revised. 1 Scope This European Standard specifies perf
21、ormance, security and safety requirements (including test methods) for single point bolts and their associated keeps, used to secure, or increase the security of, doors or windows in buildings; where operation is by lever, knob, slide, pull, etc, or removable implement (but not a multiple differ key
22、) from the protected side of the leaf only. Spring engaging bolts, and bolts with locking facility are included if they are, by definition, bolts (see 3.1 .I). The following types are therefore included: - barrel bolts, tower bolts; - foot bolts, drop bolts, square spring bolts, garage door bolts; -
23、 flush bolts (slide, knob, lever or automatic action); - padlock bolts; OBSI 02-2000 Page 4 EN 12051:1999 - locking bolts of the type where movement of the shoot is by hand, and action of the lock merely prevents withdrawal; - privacy bolts; - mortice bolts (operated by removable operating device, o
24、r fixed knob, lever etc). This European Standard does not include Cremone/Espagnolette type bolts; nor does it include bolts used for emergency exit or panic devices. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

25、ormative references are cited at the appropriate places in the text and the publications are listed below. For dated references, subsequent amendments to, or revisions of, any of these publications apply to this standard only when incorporated in it by amendment or revision. For undated references,
