14、 normally carried out through ISO technical committees.

International organizations, governmental and non-governmental, in liaison with ISO, also take part
15、 in the work. ISO collaborates closely with 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.

21、characterized by simulated destructive-windstorm events. Classification is intended as a basis for judging the ability of glazing to remain essentially without openings during a tropical cyclone with wind speed of 50 m/s or greater. Impact by missile(s) and subsequent cyclic static-pressure differen
22、tials simulate conditions representative of windborne debris and pressures in a destructive windstorm. Glazing is tested in a standard frame. Classification is based on the potential hazard to human life using the appropriate wind speed, pressure and level of protection.The test method determines th
23、e performance of security glazing for use in fenestration assemblies under conditions representative of events that occur in severe, destructive-windstorm environments using simulated missile impact(s) followed by the application of cyclic static-pressure differentials.A missile-propulsion device, a
24、n air pressure system and a test chamber are used to model some conditions that can be representative of windborne debris and pressures in a windstorm environment.The performance determined by this test method relates to the ability of glazing in the building envelope to remain without openings duri

Qualification under th

38、on, in which case, the required information, as described in Annex A, shall be provided for the test procedure.5 Apparatus5.1 GeneralAny equipment capable of performing the test procedure within the allowable tolerances may be used.5.2 Equipment5.2.1 Mounting frameThis fixture supports the outer spe
39、cimen test frame(s) described in Annex B in a vertical position during testing. The maximum mounting-frame deflection of the longest member (either during impact or at the maximum specified static air-pressure differential) shall not exceed L/360, where L denotes the longest unsupported length of a
40、member of the mounting frame. Frame-deflection measurements shall be made normal to the plane of the specimen at the point of maximum deflection. The mounting frame shall be either integral with the test chamber or capable of being installed into the test chamber prior to or following missile impact
41、(s). The mounting frame shall be anchored so it does not move when the specimen is impacted. The specifications for the inner and the outer specimen-support frame are shown in Annex B.5.2.2 Air-pressure cycling test chamberThis consists of an enclosure or box with an opening against which the test s
42、pecimen is installed. It shall be capable of withstanding the specified cyclic static-pressure differential. The chamber shall be deep enough to avoid contact with the test specimen during pressure cycling. Pressure taps shall be provided to facilitate measurement of the cyclic static-pressure diffe
43、rential. They shall be located such that the measurements are unaffected by the air supplied to or evacuated from the test chamber or by any other air movements.5.2.3 Air-pressure systemA controllable blower, a compressed-air supply/vacuum system or other suitable system capable of providing the req
44、uired maximum air-pressure differential (inward and outward acting) across the test specimen. Specified pressure differentials across the test specimen shall be imposed and controlled through any system that subjects the test specimen to the prescribed test-loading programme. Examples of suitable co
45、ntrol systems include manually operated valves, electrically operated valves or computer-controlled servo-operated valves.
