Physical testing
In addition to XRF analytics we determine the following physical parameter:
- Moisture content, loss on ignition
- grain size distribution by sieving
- open porosity
- water absorption
- bulk density
- apparent density
Our test procedures
- DIN 51081:2002-12 - Testing of oxidic raw materials and materials - Determination of change in mass on ignition
- DIN EN ISO 26845:2008-06 - Chemical analysis of refractories - General requirements for wet chemical analysis, atomic absorption spectrometry (AAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) methods (ICP-AES)
- DIN EN 993-18:2002-11 - Methods of test for dense shaped refractory products - Part 18: Determination of bulk density of granular materials by the water method with vacuum
