Scope

This Part of GB/T 3810 specifies the determination methods of ceramic tiles’
water absorption, apparent porosity, apparent relative density, and bulk density.
For open pores of the samples to inhale saturated water, there are 2 methods.
Soaking under boiling and vacuum conditions. Boiling method is that water
enters into the easily-immersed open pores; and vacuum method is that water
fills the open pores.
Boiling method applies to classification of ceramic tiles and product
descriptions. Vacuum method applies to determination of apparent porosity,
apparent relative density, and water absorption except classification.

Summary	This standard specifies the ceramic tiles water absorption, apparent relative density and bulk density determination, apparent porosity. Opening the suction hole of the sample saturated with water, there are two methods: immersion in boiling and under vacuum conditions. Easily immersed into boiling water method of opening pores, vacuum method of water filled pore openings. Boiling method is suitable for ceramic tiles classification and product descriptions, vacuum law applies to the apparent porosity, density and water absorption in addition to determination of the apparent relative classification.
