We test and classify the fire behavior of building materials according to the following standards:
| DIN 4102-1 | Fire behavior of building materials and building components – part 1: Building materials |
| DIN 4102-7 | Fire behavior of building materials and building components – part 7: roofings |
| DIN 4102-14 | Fire behavior of building materials and building components – part 14: Floorings and floor coatings |
| EN 13501-1 | Classification of building products and constructions according to their fire behavior, part 1: Classification with the results from the tests on the fire behavior of building products |
| EN 13501-5 | Classification of building products and constructions according to their fire behavior, part 5: Classification with the results from the roof tests in case of fire from the outside |
We test in detail:

This is how it works::
A proof of usability is required if the building material is used as building product in the sense of the regional building laws (MBPO § 17, paragraph 3).
This proof shall be provided by:
-a general building authority/technical approval or by
- a general appraisal certificate (German abbreviation: abP) or by
- an approval in individual cases
For better understanding, we graphed the flow chart of the testing-, monitoring- and certification process below:
