Testing and experimental facilities for technical insulation materials

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 level (notified body).

The special expertise shows the leading cooperation in the “Laboratory Group” for the voluntary European certification scheme VDI / KEYMARK, in which the registered laboratories audit each other and confirm the measurement accuracy by round robin tests.

Among others, the performance of technical insulation materials is tested by tests according to EN 14303 – 14309, EN 14313, EN 14314.

We perform the following tests:

Thermal conductivity of insulation materials

according to the test specifications of DIN EN 12667, ISO 8302 and ASTM C 177

in the temperature range of -180 °C to 900 °C

Thermal conductivity of pipe insulation materials and pipe insulation systems

according to the test specifications of DIN 52613 and DIN EN ISO 8497

in the temperature range of -70 °C to +300 °C mean temperature
at 40 °C mean temperature for insulation materials for heating systems
at 50 °C mean temperature for district heating pipes

Dimensional stability
