CEN/TC 194/WG 3 - Non-metallic tableware

This European Standard specifies a method for the determination of the resistance to microwave heating of cookware made of ceramic, glass, glass-ceramic or plastics.
It is applicable to articles that are intended for multiple re-use in a microwave oven. It is not applicable to articles, particularly those made from plastics, which are intended to be discarded after one use.

This European Standard specifies a rapid method for testing the dishwashing resistance of catering articles made of ceramics. It does not define the number of dishwashing cycles that any given product should withstand.  The method tests the dishwashing durability of the glaze surface of the ceramic articles.

This European Standard specifies a rapid method for testing the dishwashing resistance of ceramic articles intended for domestic use. It does not define the number of dishwashing cycles that any given product should withstand.

This European Standard specifies a method for testing the resistance of domestic articles made from ceramic, glass, glass ceramic, vitreous enamel, metal and plastics under the combined chemical, thermal and mechanical stresses of mechanical dishwashing in domestic dishwashers.
It specifies a reference test method for domestic dishwashing only. It does not define the number of dishwashing cycles which any given product shall withstand.

This European Standard specifies two test methods (methods A and B) for the determination of crazing resistance of glazed ceramic tableware articles in contact with food with water absorption higher than 0,5 % (determined according to method C of EN 1217:1997). Method A is a test for resistance to crazing due to moisture expansion. Method B is a test for resistance to crazing due to thermal shock and is similar in most respects to EN 1183: 1997.

This European Standard specifies the conditions for the visual inspection of non-metallic tableware in contact with foodstuffs after testing its dishwashing resistance according to the procedures described in the relevant parts of the EN 12875 series for articles for domestic, industrial and catering use.

This standard gives a method of test for determination of the resistance to mechanical shocks of articles used in catering and industrial services where they are subject to substantial and frequent shocks. It is well known that the results of this test procedure depend upon the details of the test conditions. The results therefore cannot be generalized for other ustensils made of the same material, nor to other test conditions. The results are only valid for the article and test conditions specified in the test report.

This European Standard defines terms related to certain materials for non-metallic tableware in contact with foodstuffs. It only includes those articles composed of the following materials: glass, glass ceramics, porcelain, vitreous china/vitrified tableware, stoneware, earthenware, common pottery or plastic.

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.

This European Standard specifies test methods for the determination of the translucency of ceramic articles. Two methods are described: - Method A, a qualitative method for estimating translucency, applicable to ceramic articles within a specified thickness range. - Method B, a quantitative method for the determination of body translucency requiring test specimens to be cut from ceramic articles.

This European Standard specifies test methods for thermal shock and for thermal shock endurance for brittle materials, for instance glass, glass-ceramic and ceramics. Two test methods are described: Test method A is used for articles known to be sensitive to thermal shock; test method B is generally applicable. The test method to be applied depends on the intended use of the article and/or its thermal shock resistance.

This European Prestandard specifies a method for testing the resistance of domestic articles made from ceramic, glass, glass ceramic, vitreous enamel, metal and plastics under the combined chemical, thermal and mechanical stresses of mechanical dishwashing in domestic dishwashers. It specifies a reference test method for domestic dishwashing only. It does not define the number of dishwashing cycles which any given product shall withstand.

This prestandard specifies two test methods (methods A and B) for the determination of crazing resistance of glazed ceramic tableware articles in contact with food with water absorption higher than 0,5 % (determined according to method C of EN 1217:1997). Method A is a test for resistance to crazing due to moisture expansion. Method B is a test for resistance to crazing due to thermal shock and is similar in most respects to EN 1183: 1995.
