Test and experimental facilities for insulation materials in construction

FIW München is recognised and accredited as a testing laboratory pursuant to EN ISO/IEC 17025 on a national (testing, surveillance and certification body) and European (notified body) level.

Its special expertise is further exhibited by its leading cooperation in the “Lambda Expert Group” for the voluntary European certification scheme CEN KEYMARK, whereby laboratories registered to determine the thermal conductivity of thermal insulations materials audit each other’s work and confirm measuring precision through interlaboratory testing.

The performance of insulation material is audited through tests after EN 13162 - EN 13171. We perform admission trials for new insolation material after testing schedules of the DIBt and first trials for insulation material after the testing schedule of the DIBt for design approvals (BAG) or of the European Assessment Document (EAD).

Beside this we perform the following tests:

Fire behaviour and carbonization/smouldering

Classification of the fire behavior after DIN EN 13501-1, class A1, class E
Ignitability of products subjected to direct impingement of flame according to DIN EN ISO 11925-2
