This Standard specifies a test method for the resistance of security glazing products to destructive-windstorm events.

The test conditions for judging the ability of glazing to remain essentially without openings during a typhoon, etc. with the basic wind speed of 30 m/s or greater.

Impact by missile(s) and subsequent cyclic static-pressure differentials simulate conditions representative of windborne debris and pressures in a destructive windstorm.

The selection of test conditions is based on the potential hazard to human life using the appropriate wind speed, static-pressure differential, height of fenestration assembly and level of protection.

Glazing is tested in a standard test frame.

The test method determines the 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 positive (or negative) cyclic load test.

A missile-propulsion device, an 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 and penetrations during a windstorm.

A tornado is deemed as a transient destructive-windstorm having a basic wind speed of over 48 m/s.

This Standard does not cover a tornado because its wind power does not last long and the positive (or negative) cyclic load test cannot be applied.

NOTE The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 16932: 2016 Glass in building—Destructive-windstorm-resistant security glazing—Test and classification (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
