High Temperature Testing

High temperature testing incorporates a variety of thermal properties including thermal conductivity by fundamental and comparative gradient methods, linear expansion, pyrometric cone equivalent, permanent linear change, creep and refractoriness-under-load (RUL) in compression tested to the international standards BS 1902/EN 993.

  • Thermal conductivity to BS 1902-5.5 panel method by fundamental calorimetry up to 1400°C for thermal conductivity ranges of 0.05 Wm-1K-1 to 20 Wm-1K-1 for dense refractories, solid and loose-fill insulation.
  • Thermal conductivity to BS 1902-5.8 split column method up to 1000°C for more conducting materials such as SiC and those requiring a reducing or inert atmosphere (1 Wm-1K-1 to 300 Wm-1K-1).
  • Thermal expansion to BS 1902-5.3 up to 1600°C capable of measuring dual samples to within 1 μm in both air and inert atmospheres.
  • Determination of melting point using pyrometric cone equivalent (PCE) to BS 1902-5.2 up to a temperature of 1800°C.
  • Permanent linear change (PLC) to BS1902-5.9 up to a temperature of 1600°C.
  • Refractoriness under load and creep in compression to BS 1902-4.9 and BS 1902-4.10 respectively to a temperature of 1600°C.

Typical Applications

High temperature testing of refractories and insulators finds many applications in furnace and kiln design and manufacture examining the thermodynamic and thermomechanical characteristics of load-bearing refractory materials and insulation structures.  High temperature testing in conjunction with our refractories consultancy service enables the design, production and maintenance of energy-efficient, structurally safe and long-lived furnaces and other high temperature environments for a range of industries.
