This European Standard specifies test methods for the determination of the water absorption of ceramic articles. Three test methods are described: - Test method A, based on the increase in mass of test specimens after immersion in boiling water under defined conditions, which requires test specimens with not more than one glazed surface; - Test method B, based on the same principle and general procedure as method A but with a longer period of immersion in boiling water; - Test method C, based on the increase in mass of test specimens after a combination of evacuation of the test specimens to assist water penetration, followed by immersion in water and boiling.
