Changes in permissible limits of lead and cadmium release from ceramic ware and comparative analysis of the limits at domestic and international standards

日用陶瓷制品的重金属铅、镉迁移量一直是陶瓷产品关注的重点。在日用陶瓷产品标准中也给出了限量要求,并不断地进行了修订,特别是近年来,国家对食品及相关产品质量安全高度重视,对陶瓷制品的铅、镉迁移量做出了重新整合和制订。本文总结了国内关于陶瓷制品铅、镉迁移限量的变迁,回顾了国内对陶瓷产品质量不断提升的历程,对比分析了国外主要相关标准的限量,确定了我国目前陶瓷制品的铅、镉限量所处的水平,阐述了新标准的实施的要点。

The migration of heavy metals lead and cadmium in daily ceramic products has always been the focus of ceramic products. In the standard of ceramic products for daily use also gave the limited requirements, and constantly revised. Especially in recent years, the state has attached great importance to the quality and safety of food and related products, and has re-integrated and formulated the migration of lead and cadmium in ceramic products. This paper summarized the change of the limit of lead and cadmium migration for ceramic products in China, reviewed the process of improving the quality of ceramic products in China, compared and analyzed the limit of lead and cadmium for ceramic products in foreign countries, determined the level of the limit of lead and cadmium for ceramic products in China, and expounded the key points of the implementation of the new standard.
