Household Ceramics International Standard Summary
Ceramics using is a very wide range, therefore, came into being particularly multi-criteria such as: ceramics for daily contact with international standards by ISO / TC 166 with food ceramics, glass ceramics (Ceramic ware, glassware and glass ceramic ware in contact with food) technical Committee to develop, its secretariat is in ANSI (American national Standards Institute), there are currently 12 participating countries (Participating country) and 32 observer countries (Observing country).
Standardized specifications in contact with food contents ceramics, glass and glass ceramic ware TC 166 related, but not including glass and porcelain enamel ware, this part of the work belongs to the category TC107 metals and other inorganic coatings (Metallic and other inorganic coatings) technology committee. TC 166's have a branch committee (sub-committee), referred to as SC1 and a working group (working group), and referred to WG1. In the six standard TC166 developed, in which SC1 developed two standards, test methods and content are the limits for lead, cadmium dissolution.
Generally speaking, the ceramic materials have a high hardness, and relatively poor plasticity. In addition to use in tableware and decorative use in the development of science, technology plays an important role in Italy. Ceramic materials are a lot of resources on Earth original soil after extraction from, and the nature of clay has toughness at room temperature water can sculpture, sculpture can also be a little dry, completely dry, you can wear; burn 700 degrees, can be made pottery filled with water use; burn 1230 degrees is porcelain, porcelain will completely dilute in water and high temperature corrosion. It can be seen, the use of ceramics is a considerable flexibility, in order to be more effective and safe use of ceramics, all relevant norms also emerged.
Standards are as below:
※ISO 6486-1999 Ceramic ware, glass-ceramic ware and glass dinnerware in contact with food--Release of lead and cadmium--Part 1：Test methods.
※ISO 6486-1-1999 Ceramic ware, glass-ceramic ware and glass dinnerware in contact with food--Release of lead and cadmium--Part 2：Permissible limits.
※ISO 7086-1-2000 Glass hollowware in contact with food--Release of lead and cadmium--Part 1: Test method.
