This European Standard specifies test methods for the determination of the water absorption of ceramic articles. Three test methods are desribed: - Test method A, based on the increase in mass of test specimens after immersion in boiling water under defined conditions, requiring 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.

Applies to ceramic cookware, intended to be used for the preparation of foods by heating. The determination is carried out by extraction of the cookware surfaces with hot acetic acid solution (4 %), and determination of the lead and cadmium extracted by means of the atom absorption spectroscopic method.
