3、 20 Switzerland Internetisoiso.ch Printed in Switzerland ii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical commit
4、tees. 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 with the In
5、ternational 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 3. Draft International Standards adopted by the technical committees are circulated to the member b
6、odies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 15082 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 11, Safety glazing materials. Annex A of this Internationa

39、out from the flattest part of a plastic safety glazing material. 9.2.4 Procedure Place a conditioned test specimen in the supporting fixture and conduct the impact test at once. To minimize the temperature change of test specimens conditioned at low temperature, the test should take place as quickly
40、 as possible (within 30 s of its removal from the conditioning appliance). The plane of the test specimen shall be perpendicular, within 3, to the incident direction of the ball. When necessary to retain the test specimen in the fixture, it shall be clamped to ensure that the movement of the test sp

43、f results Evaluate the ability of the plastic safety glazing material to support the impacting ball for each velocity and temperature. If the ball passes completely through a test specimen within 5 s after impact, the result shall be recorded as a “non-support“. If the ball remains on top of a test
