Testing device SPT ISO/DIS 9150


  • Determining the protection provided by materials under heat exposure when welding or with other related procedures.

A steel cylinder in a steel cone and in an oven is heated to a temperature of 600°C. After the heating the steel cone is put onto a mechanism which is on top of the calorimeter and the specimen. When triggering the magnetic switch the steel cylinder vertically falls onto the specimen. The calorimeter measures the starting temperature, the maximum temperature and the maximum difference. Before and after the test the calorimeter is adjusted to 20°C by a cooling and heating unit. The software manages the controlling, calculations and evaluation of the standard. The power supply for the controller is provided by an IEC-320 AC power cordset 230 VAC (50/60 Hz).
