Notes:
(*) The batch size of ceramic floor and wall tiles is not greater than 1500 m2. For product (no. 1, Section III Table 1), clearly specify the sampling guidelines and specifications to be checked as follows:
- For tiles whose edge is less than 2 cm (possibly in the form of pieces/slabs or a sheet): it is necessary to check the specifications: 1., 5, 6; number of test samples: 12 whole pieces or not less than 0.25 m2.
- For tiles whose edge is 2 cm to less than 10 cm (possibly in the form of pieces/slabs or a sheet): it is necessary to check the specification: 1., 3., 5, 6; number of test samples: 12 whole pieces or not less than 0.25 m2.
- For tiles whose edge is 10 cm to less than 20 cm (possibly in the form of pieces/slabs or a sheet): it is necessary to check the specification: 1., 3., 4., 5, 6.; number of test samples: 20 whole pieces or not less than 0.36 m2.

(3)S is the area of the plate glass expressed as the unit of m² and around off down to the second decimal place;
(4)The permissible number of bubbles and foreign materials shall be the integer value obtained by discarding the decimal fraction of the value obtained by multiplying S by the coefficient;
(5)Linear and zonal defects are those which exist in the inside or on the surface of the glass, such as crack, scratch, non-uniformity of base, etc.
