This European Standard shall be given the status of a national standard, either by publication of an identical text o
12、r by endorsement, at the latest by May 2000, and conflicting national standards shall be withdrawn at the latest by May 2000. According to the CENCENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belg
13、ium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Introduction This European Standard assesses security glazing products that are more familiarly known as “anti-bandit
14、” and “anti-vandal” glazing products. Because there is no single test that will cover the wide range of resistances to attack, two separate test methods are used to give a continuous range of categories of resistance. It is not intended that either test method be associated with the terms “anti-band
15、it” or “anti-vandal”, particularly since these terms can be only loosely defined and there is considerable overlap in their definition. The test methods specified in this standard do not reproduce the conditions of real human attack, but are intended to give a classification of comparative resistanc
16、e. STD-BSI BS EN 35b-ENGL 2000 Lb2LibbS OBLiBb4L Lb2 Page 3 EN 356: 1999 1 Scope This European Standard specifies requirements and test methods for security glazing designed to resist actions of force by delaying access of objects and/or persons to a protected space for a short period of time. This
17、standard classifies security glazing products into categories of resistance to actions of force. In this European Standard, the categories of resistance have not been assigned to special applications. Selection of categories should be made by the user for every individual case, after consulting an e
18、xpert if necessary. NOTE 1 : Security glazing products should be installed in a frame which can give appropriate resistance to attack and which also provides a suitable support for the security glazing product. NOTE 2: Cut-outs and holes in security glazing products should be avoided where possible,
19、 as these can affect the resistance of the product. This European Standard deals with mechanical resistance to attack only. Other properties can also be important, for which separate standards will be prepared. 2 Normative references This European Standard incorporates by dated or undated refererenc
20、e, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated
21、 in it by amendment or revision. For undated references, the latest edition of the publication referred to applies.
