9、 The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-

10、governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part

11、2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a

12、 vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 16936-4 was prepared by Technical Committee ISO/TC 160, Glass in building, Subcommittee SC

13、 2, Use considerations. ISO 16936 consists of the following parts, under the general title Glass in building Forced-entry security glazing: Part 1: Test and classification by repetitive ball drop Part 2: Test and classification by repetitive impact of a hammer and axe at room temperature Part 3: Tes

14、t and classification by manual attack Part 4: Test and classification by pendulum impact under thermally and fire stressed conditions ISO 16936-4:2005(E) ISO 2005 All rights reserved vIntroduction ISO 16936 assesses security-glazing products that are more familiarly known as “anti-vandal”, “anti-ban

15、dit”, and detention glazing products. Because there is no single test that will cover such a wide range of resistance to attack, four separate test methods are provided to assess the forced entry resistant properties of security glazing. It is not intended that any particular test method be associat

16、ed with the terms “anti-vandal” or “anti- bandit”, since these terms can be only loosely defined and there is considerable overlap in their definition. The test methods specified in this part of ISO 16936 do not reproduce the conditions of real human attack, but are intended to provide a means of cl

17、assifying glazing based on comparative resistance to certain forms of mechanical attack.

18、tions 1 Scope This part of ISO 16936 specifies requirements and mechanical test methods for security glazing designed to resist actions of manual attack by delaying access of objects and/or persons to a protected space for a short period of time. It also classifies security-glazing products into cat

19、egories of resistance against manual attack under thermally and fire stressed conditions. NOTE Classifications have not been assigned to specific applications and glazing classification must be specified on an individual basis for every application. 2 Terms and definitions For the purposes of this d

20、ocument, the following terms and definitions apply. 2.1 action of force deliberate action on the part of a person made with the intention of creating a hole in the security-glazing product by the use of manually held implements or by the use of thrown objects 2.2 attack face face of a test piece mar

21、ked by the manufacturer and/or supplier that is designed to face the attack 2.3 category of resistance classification of the capability of a security-glazing product to resist actions of force 2.4 performance characteristic response of the glazing sample in any one of the tests according to this par

22、t of ISO 16936 2.5 protected space space protected against access by the completed installation 2.6 sample specified number of test pieces which together are representative of the security-glazing product intended to comply with a particular category of resistance specified in ISO 16936 ISO 16936-4:

23、2005(E) 2 ISO 2005 All rights reserved2.7 security-glazing composition specific construction of a glazing product NOTE A product is deemed to be of the same or superior security-glazing composition if individual plies are exchanged with others of a different colour, but without significant effect on

24、 the resistance to actions of force, and/or additional glazing products are installed on either face of the security-glazing product, laminated to it or with an air space, and/or additional equipment such as alarm wires, heating wires, printing, or surface coatings (on part or all of the surface) ar

25、e incorporated into the security-glazing product, provided that this does not significantly affect the resistance to actions of force. 2.8 security-glazing product product based on glass with or without plastics with a single or multiple ply construction, where the individual plies are of uniform th

26、ickness over the whole area of the product. NOTE A security-glazing product is usually transparent or translucent, and provides a specific resistance to the actions of force. 2.9 test piece specified piece of security-glazing product submitted to a specified test procedure 3 Significance and use IMP

27、ORTANT Security-glazing products should be installed in a frame which can give appropriate resistance to impact and which also provides a suitable support for the security-glazing product. Cut-outs and holes in security-glazing products should be avoided where possible, as these can affect the resis

28、tance of the product. The test methods given in this part of ISO 16936 aid in assigning a level of physical security to glazing used in window and door assemblies based upon objective tests which can be consistently duplicated. These test methods evaluate the resistance of security glazing to attack

29、s using blunt and sharp impact devices and fire. The test methods evaluate the performance of glazing in hot and cold environments, but do not provide a measure of the resistance or performance of glazing subjected to attack by ballistics, chemical agents, explosives or other extreme methods of atta

30、ck. Where such elements are a factor, consult the manufacturer. 4 Sample selection, size, and specimen preparation 4.1 The sample submitted for testing shall consist of three test pieces one for each test. NOTE To ensure against invalid test results because of errors during the test, it is advisable

31、 to submit at least one extra test piece. 4.2 Each test piece shall be (1 100 5) mm long (900 5) mm wide. The edges shall be free from visible chips, cracks and flaws. Glass samples should be lightly arrissed for ease of handling. 4.3 Figure A.1 shows an acceptable test fixture sketch and the locati

32、on of the strike points specified in Tables 1 and 2. 4.4 For non-symmetrical materials, the attack face of the product shall be identified by the manufacturer and attacked during the test process.
