Scope
This standard specifies the instruments, measurement steps, and result calculation for determining the density of glass using the method of comparing buoyancy.
This standard is applicable to determining the density of glass or other non-porous solids with a density range of 1.1 g/cm3 to 3.3 g/cm3, and can also be used to determine the apparent density of ceramics or solids with known porosity.
