The work of preparing International Standards is normally carried ou
9、t 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-governmental, in liaison with ISO, also take part in the work. ISO co
10、llaborates 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 2. The main task of technical committees is to prepare International
11、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 vote. Attention is drawn to the possibility that some of the element
12、s 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 16936-1 was prepared by Technical Committee ISO/TC 160, Glass in building, Subcommittee SC 2, Use considerations. ISO 16936 consists of the following parts, un
13、der 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: Test and classification by manual attack Part 4: Test and classification
14、 by pendulum impact under thermally and fire stressed conditionsISO 16936-1:2005(E) ISO 2005 All rights reserved v Introduction This part of ISO 16936 assesses security-glazing products that are more familiarly known as “anti-vandal”, “anti-bandit” and “detention” glazing products. Because there is
15、no single test that will cover the wide range of resistances 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 associated with the terms “anti-vandal” or “anti-bandit”, since t
16、hese terms can be only loosely defined and there is considerable overlap in their definition. It is important that security glazing products be installed in a frame which can give appropriate resistance to impact and which also provides a suitable support for the security-glazing product. It is impo
17、rtant that cutouts and holes in security glazing products be avoided where possible, as these can affect the resistance of the product. The test method specified in this part of ISO 16936 does not reproduce the conditions of real human attack, but is intended to give a classification of comparative
18、resistance vi INTERNATIONAL STANDARD ISO 16936-1:2005(E) ISO 2005 All rights reserved 1 Glass in building Forced-entry security glazing Part 1: Test and classification by repetitive ball drop 1S c o p e This part of ISO 16936 specifies requirements and a test method for security glazing designed to
19、resist impacts of a hard body by delaying access of objects and/or persons to a protected space for a short period of time. This part of ISO 16936 classifies security-glazing products into categories of resistance to repetitive impacts of a steel sphere. In this part of ISO 16936, the categories of
20、resistance have not been assigned to special applications. Glazing classification should be specified on an individual basis for every application. This part of ISO 16936 deals with mechanical resistance to impact only. Other properties can also be important. 2 Normative references The following ref

The equipment for holding the impactor and the mechanism for releasing the impactor shall not induce any momentum or rotation in the impactor,
34、so that the impactor is accelerated only by gravitational forces and falls vertically. 5.3 Test piece support apparatus, consisting of a steel frame to clamp the edge of the test piece and a receiving box to collect fragments and the impactor (see Figure 1). The support apparatus shall be inherently
35、 rigid; have an unyielding connection to a solid base; ensure plane and parallel clamping of the test piece in a horizontal position; be designed in such a way that the test piece touches only the clamping frame during the test; ensure clamping of the test piece on all four edges with an edge cover
36、of ( ) ; have the clamping frame covered on the contact area of the test piece with rubber strips wide andthick of hardness 40 IHRD to 60 IHRD, according to method N of ISO 48:1994; ensure that the edges of the test piece are clamped with a uniform pressure of ( ) ; ensure that the impactor is not d
37、amaged and does not rebound when hitting the bottom of the receiving box; ensure that air cannot be trapped in the support apparatus in such a way that it may cushion the effects of the impact. 6 Required characteristics The security-glazing product shall be submitted to testing for a particular cat
38、egory of resistance. The security glazing product shall be classified in that particular category of resistance if all three test pieces (or all six test pieces in the case of an asymmetric material) prevent penetration by the impacting body when tested by the method described in Clause 7. 7 Test me

43、1:2005(E) ISO 2005 All rights reserved 5 For categories P1A, P2A, P3A and P4A, the impactor shall be dropped on each test piece three times from the same height, in such a way that the impact positions form the pattern of an equilateral triangle with a side length of ( ) around the geometric centre
44、of the test piece, with one side of the triangle parallel to a short side of the specimen. The impact position opposite to this side of the triangle shall be hit first. For the category P5A, the above procedure shall be repeated a total of three times on each test piece, giving nine impacts, three o
45、n each point of the triangle. Loose fragments shall be removed from the test piece after each impact for all levels. For asymmetric constructions, carry out the test on both sides, i.e. the test shall be carried out first on one side and, if successful, it shall be repeated by impacting the other su
46、rface of the test piece. 7.4 Evaluation of the test results After each impact, the test piece shall be checked for penetration by the impactor. A test piece shall be regarded as being penetrated if the impactor has completely passed through the test piece before five seconds has elapsed since the ti
47、me of impact. After each impact, the test piece shall be also examined for signs of slippage from the clamping frame. The test is invalid if any edge of the test piece has moved more than in the clamping frame. If this is the case, then the test shall be repeated with a new test piece. If it is foun
48、d to be necessary to increase the clamping pressure to prevent slippage, this shall be stated in the test report. The clamping pressure should not exceed . High clamping pressures can make a product unsuitable for use in insulating glass units. 8 Classification and designation The security glazing p
49、roduct shall be classified in that category of resistance corresponding to the applied drop height and number of impacts, provided all test pieces have resisted penetration by the impactor. Table 2 gives the code designations for the categories of resistance. 9 Test report The following items shall be included in the test report: name of the testing laboratory; test number; date of test; reference to this part of ISO 16936; name of the compa
