Torbjørn Knarvang

Senior Engineer

Torbjørn Knarvang's primarily work on material testing relates to methods based on different ISO- standards (ISO 4049, ISO 10477, 20795-1 and ISO 20795-2). He is involved in research across various fields and is responsible for a considerable number of instruments at NIOM. Further he performs analyses on Fourier-transform infrared spectroscopy, and he is ensuring that our conditioned rooms function at all times.
