HIGH TEMPERATURE HOT MODULUS OF RUPTURE (HMOR)
Determination of the High Temperature Hot modulus of Rupture (HMOR) / Ceramic Complying with IS:10570-2011, IS:1528(Part 20)-1993 & ISO:5103-1985 for a batch of 5 Samples - Sending - regarding.
Consist of a High-Temperature Furnace: Capable of heating specimens upto 1400°C Supplied without prismatic bars (150 X 25 X 25mm)
Test Procedure:
- Test Specimen: The standard typically requires prismatic bars, which may have dimensions like 150 mm x 25 mm x 25 mm.
- Heating: The specimen is heated to a predetermined temperature (usually 1200°C, 1400°C, or another relevant temperature depending on the material).
- Loading: Once the desired temperature is reached, a three-point bending test is conducted. The force is applied at a uniform rate until the specimen breaks.
- Calculations: The modulus of rupture (MOR) is calculated using the standard formula for flexural strength:
