81.060.20 - Ceramic products

This document gives specifications, test methods, sampling, marking and labelling of porcelain tableware that is used for the preparation and serving of foods.

This document specifies a test method for the release of lead and cadmium from ceramic ware, glass ceramic ware and glass dinnerware intended to be used in contact with food, but excluding vitreous and porcelain enamel articles (covered by ISO 4531). This document is applicable to ceramic ware, glass ceramic ware and glass dinnerware which is intended to be used for the preparation, cooking, serving and storage of food and beverages, excluding all articles used in food manufacturing industries or in which food is sold.

This part of ISO 6486 specifies permissible limits for the release of lead and cadmium from ceramic ware, glassceramic ware and glass dinnerware intended to be used in contact with food, but excluding porcelain enamel articles. This part of ISO 6486 is applicable to ceramic ware, glass-ceramic ware and glass dinnerware which is intended to be used for the preparation, cooking, serving and storage of food and beverages, excluding articles used in food manufacturing industries or those in which food is sold.

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.

This pre-standard describes a method for statistical analysis of ceramic strength data in terms of a two-parameter Weibull distribution using a maximum likelihood estimation technique. It assumes that the data set has been obtained from a series of tests under nominally identical conditions.
