Physical testing - CRB

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
Physical testing bulk density, Loss on ignition, ash-content - CRB GmbH

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
