ISO/TC 160/SC 2/WG 7 - Security glazing tests

This document specifies requirements and a test method for security glazing designed to resist impacts of a hard body by delaying access of objects and/or persons to a protected space for a short period of time. It also classifies security-glazing products into categories of resistance to repetitive impacts of a steel sphere. In this document, the categories of resistance have not been assigned to special applications. It is intended that the glazing classification be specified on an individual basis for every application and anticipated action of force upon the glazing. This document deals with mechanical resistance to impact only. NOTE Other properties can also be important.

1.1 This document determines resistance of security glazing products to natural threats characterized by simulated destructive-windstorm events. 1.2 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 application of cyclic static-pressure differentials. 1.3 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. 1.4 The performance determined by this test method relates to the ability of glazing in the building envelope to remain without openings during a windstorm.

ISO 16933:2006 provides a structured procedure to determine the air-blast resistance of glazing and sets forth the required apparatus, procedures, specimens, other requirements and guidelines for conducting arena air-blast tests of security glazing. Seven standard blasts simulating vehicle bombs and seven standard blasts simulating smaller satchel bombs that can be used to classify glazing performance are incorporated in this International Standard and cover a broad range of blast parameters. Security glazing, including that fabricated from glass, plastic glazing sheet material, glass-clad plastics, laminated glass, insulated glass, glass/plastic glazing materials and film-backed glass, can be tested and classified in a standard frame or tested but not classified in frames provided with the glazing. Classification and ratings are assigned based on the performance of glazing loaded by air-blast pressures and impulses and are specific to the blast characteristics under which the test takes place. Glazing that has received an air-blast classification and rating is suitable for use in blast-resistant applications only for blasts of comparable characteristics and only if installed in a properly designed frame. Design based on knowledge of the air-blast resistance reduces the risk of personal injury.

ISO 16934:2007 specifies a shock tube test method and classification requirements for explosion-pressure-resistant glazing, including glazing fabricated from glass, plastic, glass-clad plastics, laminated glass, glass/plastic glazing materials, and film-backed glass. ISO 16934:2007 provides a structured procedure to determine the blast resistance and the hazard rating of glazing and glazing systems. ISO 16934:2007 sets out procedures to classify such security glazing sheet materials by means of tests on specimens of a standard size in a standard frame for the purpose of comparing their relative explosion resistance and hazard rating. The procedures and test method can also be used to test, but not classify, glazing systems where the sheet in-fill is incorporated into frames purposely designed as complete products of appropriate size for installation into buildings. ISO 16934:2007 applies a method of test and classifications against blast waves generated in a shock tube facility to simulate high-explosive detonations of approximately 30 kg to 2 500 kg TNT at distances from about 35 m to 50 m. The classifications approximately represent the reflected pressures and impulses that are experienced by these equivalent threat levels on the face of a large building facade positioned perpendicular to the path of the blast waves. Classification is defined in terms of both blast shock-wave characteristics, expressed in terms of peak reflected pressure, impulse, positive phase duration and wave-form parameter (decay coefficient), and rating criteria, expressed in terms of degrees of glazing damage and fragment impact hazard. Classifications and ratings are assigned based upon the performance of the glazing and are specific to the blast characteristics under which the test has taken place. Glazing that has received an air-blast classification and rating is suitable for use in blast-resistant applications only for blasts of comparable characteristics and only if installed in a properly designed frame. Design based on knowledge of the air blast resistance reduces the risk of personal injury.

ISO 16935:2006 sets forth test procedures to evaluate resistance of security glazing materials and products against ballistic impact with classification by weapon and ammunition. ISO 16935:2006 is applicable to attack by handguns, ammunition fired from machine pistols or submachine guns, rifles and shotguns, on products used for glazing in buildings, for both interior and exterior use. ISO 16935:2006 assumes the glazing is adequately fixed, but does not apply to the glazing system or the surrounding materials and structure.

ISO 16936-2:2005 specifies requirements and a mechanical test method for security glazing designed to resist actions of manual attack by delaying access of objects and/or persons to a protected space for a short period of time. ISO 16936-2:2005 classifies security glazing products into categories of resistance against repetitive impacts of a hammer and an axe. The categories of resistance have not been assigned to special applications. Glazing classification should be specified on an individual basis for every application. ISO 16936-2:2005 deals with mechanical resistance to manual attack only.

ISO 16936-3:2005 sets forth a physical test method for security glazing designed to resist actions of manual attack by delaying access of objects and/or persons to a protected space for a short period of time. Its application is limited to the evaluation and the classification of the resistance of forced entry security glazing against the following threats: blunt tool impacts; sharp tool impacts; thermal stress; chemical stress (optional). It is not applicable to the use of power (motor- or engine-driven) tools or devices, explosives, military ordinance and tools, and processes or devices requiring more than two persons to transport and operate.

ISO 16936-4:2005 specifies requirements and mechanical test methods for security glazing designed to resist actions of manual attack by delaying access of objects and/or persons to a protected space for a short period of time. It also classifies security-glazing products into categories of resistance against manual attack under thermally and fire stressed conditions.

ISO 16932:2016 determines resistance of security glazing products to natural threats 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 differentials 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 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 application of cyclic static-pressure differentials. 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 during a windstorm.

ISO 16932:2007 determines resistance of security glazing products to natural threats characterized by simulated destructive-windstorm events. Classification is intended as basis for judging the ability of glazing to remain without openings during a severe tropical cyclone with sustained wind speed of 50 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. Glazing is tested in a standard frame. Classification is selected for a geographical location using the appropriate wind speed, pressure and level of protection. 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 application of cyclic static-pressure differentials.
