Introduction of GB/T 1970-1996

1 Subject Content and Application Scope This standard specifies the test method for acid and alkaline-resistance of porous ceramic. This standard is applicable to the determination of acid and alkaline-resistance of porous ceramic. 2 Method Summary 2.1 Strength reduction method: boil the specimens of porous ceramics in 20% sulfuric acid solution (or 1% sodium hydroxide solution) for 1h and calculate the reduction rate of bending strength than that before corrosion. 2.2 Mass loss method: boil particle specimens in 20% sulfuric acid solution (or 1% sodium hydroxide solution) for 1h and calculate the loss rate of mass than that before corrosion. 3 Apparatuses and Reagents
