Refractory Testing

Refractory Testing: Refractoriness under load (RUL) / Creep in compression (CIC), Modulus of Rupture (HMOR)

 

Special strength-testing methods have been established for refractory ceramics, which are of a mostly heterogeneous composition. The Refractoriness under Load (RUL) and Creep in Compression (CIC) identify the deformation resistance of a test piece under a defined load and temperature/time factors.

 

The modulus of rupture at high temperatures (HMOR) is determined with a hot modulus of rupture tester. These all conform to the pertinent instrument and applications standards, e.g. ISO 1893, ISO 3187, ISO 5013, DIN EN 993-7/8/9, DIN 51048, DIN 51053, DIN 51063, DIN 51046.
