The work of preparing International Standards is normally carried out through ISO technica

8、l 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 collaborates closely wit

9、h the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed

10、for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rig

14、l rights reserved ISO 29584:2015(E) Introduction Accidental human impact with glass panes can be a source of injury. The classification of glass in terms of its ability to withstand impact and the consequences of the glass breaking under such impact has been considered in many countries. The use of

15、a soft body impactor to represent a human body has enabled regulators, code officials and other control organizations to specify glazing that reduces the risk of cutting and piercing injuries. This International Standard has been prepared as a means of detailing the differences and similarities in p

16、endulum impact tests for the classification of safety glass. The traditional impactor has been a lead shot-filled leather bag. This has been found to suffer from ageing or shape change and variability in the energy transfer into the test piece if not properly maintained. It has been found that there

17、 can be wide variation in the supporting frame or sub-frame. During their work, CEN /TC 129/WG 13 examined some of the problems associated with the lead shot- filled leather bag impactor and the supporting frame. CEN/TC 129/WG 13 prepared EN 12600 that uses an impactor consisting of steel masses and

18、 two tyres. The primary objectives in developing the new impactor for the evaluation of safety glass can be summarized as follows: a) elimination of the differences between 1) taped and un-taped lead shot bags and 2) lead shot bags and bags filled with sand or glass beads; b) ageing of lead shot bag

19、; c) elimination of the use of lead shot; d) harmonization of national impact test methods. ISO 2015 All rights reserved v Glass in building Pendulum impact testing and classification of safety glass 1 Scope The purpose of this International Standard is to evaluate, by means of soft body impactors,

20、safe breakage characteristics of glazing products intended to reduce cutting and piercing injuries to persons through accidental impact. This International Standard examines test methods currently employed to determine the pendulum impact performance of safety glass. Use of the methodologies in this

21、 International Standard improves the reproducibility of test results and gives a common basis of classification. The aim is for the performance of glass products manufactured and tested in various countries to be better understood and more consistent. Two types of soft body impactors are defined. Th

22、e traditional shot bag impactor is detailed both in terms of manufacture and maintenance in an attempt to overcome problems associated with such impactors becoming misshapen. The twin tyre impactor is also detailed. The test equipment, excluding the impactor, is also described. A method of calibrati

23、ng the test frame is given. The benefit of calibrating the test equipment is the increased reproducibility of the test results. Classification of glass products is also detailed. The classification system allows information on the following to be given: a) the maximum drop height at which the glass

24、either did not break or broke safely, i.e. in a manner similar to laminated glass or toughened glass; b) the manner in which the glass would break, i.e. as toughened glass, laminated glass, annealed glass, irrespective of whether or not the glass was broken during the test; c) the maximum drop heigh

25、t at which the glass either did not break or broke safely, i.e. in a manner similar to laminated glass. This International Standard does not specify the intended use of the products, but provides a method of classification in terms of the performance of the materials being tested. The impact energy

26、used for the various levels of classification are designed to provide the intended user or the legislator with the information to assist in defining the level of safety and protection required relative to the intended location at which the selected safety glass is to be used. 2 Normative references
