Brandbeständigkeitsprüfofen für Baustoffe

Anwendung:

DIN 4102-16 describes the uniform procedure for testing building materials in the "Brandschacht" according to DIN 4102-15. The revision of DIN 4102-16 is carried out in order to update the list of standardised products that are used in the test method. The test method is used for the fire testing of building materials. The Brandschacht is a square housing into which air at a constant flow rate is introduced from below, and from which flue gas escapes from above. It is equipped with a square gas burner by means of which the specimen arranged in a mounting frame so as to form a flue, are exposed to flaming.

Brandschacht Test Apparatus, in accordance with DIN 4102 Part 15, is designed for the fire testing of building materials and elements. The ‘brandschacht’ is a square chamber, which has a constant flow of air introduced from the bottom, and combustion gas escapes from the top of the chamber. The specimens are mounted vertically and exposed to the flame generated by a square gas burner.
