Refractories and refractory materials - Physical test methods - Refractoriness under load - Temperatures of deformation at constant load with rising temperature
Describes the procedure for the determination of refractoriness under load (RUL) or the temperatures of deformation at constant load with rising temperature. Detailed and illustrated descriptions of the apparatus is given together with the specified stress and heating schedules for the different types of refractories.
