GB/T 3000 - 2016 Porosity test of focused dense and shaped refractory products. It specifies test equipment, such as Gas flow rate devices, pressure measurement instruments, etc. Detailed sample preparation steps, specification under specific pressure and temperature, gas through the product test process. Porosity is accurately calculated according to the test data. This standard provides key testing means for manufacturers to control product mass and develop new refractory materials, and helps high-temperature industrial fields to rationally select refractory products with suitable ventilation performance according to actual working conditions to ensure stable operation of facilities.
