EN 13541 Shock tube test

Glass in building - Security glazing - Testing and classification of resistance against explosion pressure.


This European Standard specifies a test method, performance requirements and classification for explosion pressure resistant glazing for use in buildings.

The explosion pressure resistant glazing is intended to offer resistance against explosives with respect to human safety.

To view products that can offer blast resistant properties, see the below links.

Blast Resistant Doors - Steel manufactured doors offering blast protection to buildings

This European Standard concerns a method of test against blast waves generated using a shock tube or similar facility to simulate a high explosive detonation.

The classification is only valid for tested glass sizes of about 1 m2. Based on theoretical considerations and/or experimental work, the results can be used for estimating the explosion-pressure-resistance of other glass sizes.

NOTE 1 The resistance classes are not assigned to specific situations. For each individual case the individual who specifies, if necessary with the help of experts in the field of explosion, should be consulted.

NOTE 2 The protection provided by explosion-resistant-glazing not only depends on the product itself, but also on the design and fixing of the glass.
