As such non-standard glazing assemblies may only be tested but not classified in accordance 19633 this standard, the number of test specimens will be as agreed prior to test.

For example, the positive phase impulse, 7 posmay be denoted I c where it denotes the classification impulse or 7 t where it denotes the impulse calculated from the measured test values. A positive phase duration, t pos negative phase duration,? Search the history of over billion web pages on the Internet.

Glazing dust and slivers are not accounted for in the hazard rating. When the test specimens have been mounted on test frames and the high explosives has been placed and is ready to be armed, the area shall be cleared of all non-essential personnel. If present, the location of perforations and indents shall be documented, with their height above the floor of the witness area recorded.

The preliminary selection of an appropriate explosive and mass may be made by reference to Table B. Seven standard blasts simulating vehicle bombs and seven standard blasts simulating smaller satchel bombs that can be izo to classify glazing performance are incorporated in this International Standard and cover a broad range of blast parameters. In a true, free-field explosion, as the energy of the expanding gases becomes dissipated, so their momentum falls and they begin to contract. Glazing dust and slivers are all other smaller particles.


Examples of minimum sizes of glass particles classed as fragments are provided in Annex D informative. The 3 kg charges were placed at a height of 0,5 m to centre above a hard surface. As an alternative, the pressure transducers may be installed on a transducer panel of the same size as the test frame and located isso oriented in the same manner with respect to the charge as the test frame.

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.

The peak pressure, P maxof relevance is the resulting smoothed value.

If they are different, the calculation should weight the number of readings for each. The board shall be in one or two layers of combined thickness at least 35 mm, mounted in a frame capable of remaining in place even if forcibly impacted by failed pieces of the test specimen.

E Low hazard The glazing is observed to fracture, and glazing fragments or the whole of 16393 glazing fall between 1 m and 3 m behind the interior face of the specimen and not more than 0,5 m above the floor at the vertical witness panel.

The air-blast pressure transducers shall be flush with the surface of the reaction structure on the air-blast side. It is the responsibility of the test director to set up the test in order to impose the required blast values on the surface of the test specimen within the tolerances as determined by the following steps on 16933 measurements.


Bullet resistant security glazing. P-t curves at locations subject to blast clearing, on small targets or near the edges of targets, have a reduced impulse and do not follow the shape of an idealized Friedlander curve. This is accurate when the number of P r readings is the same as the number of I r readings in each example blast.

The free-field pressure transducer shall be located at least 5 m or the width of the reaction structure, whichever is greater, from any reaction structure and at the same horizontal distance from the high-explosive charge as the centre of the glazing. Worldwide Standards We can source any standard from anywhere in the world.

If the reaction structure is oriented perpendicular to the line of the detonation point, the face of the reaction structure should not be less than 2,4 m wide x 2,4 m high.

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. Also, there are no more than three rateable 1693 or indents anywhere in the witness panel and any fragments on the floor between 1 m and 3 m from the interior face of the specimen have a sum total united isso of mm or less.

Nominal charge size and nominal standoff distances capable of giving the required peak pressure and impulse values under certain conditions and when in the reflected orientation are included in Clause C. The test values applicable 1693 the centre of the test specimen for comparison with the classification criteria are to be computed from at least three gauges distributed around the face of the target area or within the simulated area if a separate transducer iiso is used see 6.
