GB/T 4100. 5- -1999
This standard is not equivalent to the Appendix 1.1 of ISO13006:1998 "Ceramic Tiles-Definition, Classification, Performance and Marking" standard. The water absorption rate E10 of pressed ceramic tiles is Class B. The technical indicators of superior products in this standard are better than those of this standard, and the technical indicators of qualified products are equivalent to those of this standard.
This standard is divided into superior products and qualified products according to the dimensional deviation and surface quality of the products. The main technical differences between this standard and GB/T4100-1992 "Glazed Interior Wall Tiles" are: the indicators such as dimensional allowable deviation, surface quality, water absorption, glaze crack resistance, and thermal shock resistance are stricter than those of this standard, and technical requirements such as breaking strength, linear thermal expansion, expansion, lead and alkali dissolution, pollution resistance, impact resistance and small color difference are added. This standard is applicable to product quality certification. When using measured values ​​or calculated values ​​to determine the limit values ​​in this standard, the comparison method of rounded values ​​is adopted. This standard replaces GB4100-1992 from the date of implementation. This standard is proposed by the State Bureau of Building Materials Industry. This standard is under the jurisdiction of Weiyang Ceramic Research and Design Institute of the State Bureau of Building Materials. The drafting units of this standard are Weiyang Ceramic Research and Design Institute of the State Bureau of Building Materials and Standardization Research Institute of the State Bureau of Building Materials. The drafting unit of this standard is Dongfo Ceramic Group Diamond Ceramic Co., Ltd. The main drafters of this standard are Shen Chaohong, Zhao Ruifang, Wang Bo, Zhang Weixing, and Liu Xiuzhen.
