4.3 Facial tissue shall be usually folded in flat or slicing. Its specification shall be in accordance with provisions of contract. Dimensional deviation of specification shall not exceed the nominal value by ±5mm; and the degree of skew shall not exceed 3mm; or be in accordance with provisions of contract. 4.4 Facial tissue can be patter-embossed or pattern-stamped. Facial tissue in various colors is also allowed. But harmful dyes shall not be used. 4.5 Facial tissue shall be clean and the puckers shall be even, fine and smooth. There shall not be obvious dead-fold, incomplete, breakage, sand, hard block, raw pulp ball and other paper defects. 4.6 There shall not be off-powder or lint desquamating from the facial tissue; and colorized facial tissue shall not fade when being soaked. 4.7 Toxic and harmful raw materials shall not be used in facial tissue. While wood, herbage, bamboo and other natural fibrous raw materials shall be used. Using any recycled paper, paper presswork, paper product and other recycled fibrous substance as the raw material must not be allowed; neither is deinking agent. 4.8 Hygienic index of facial tissue shall be in accordance with the provisions of GB 15979. 5 Test Methods 5.1 Sampling and treatment Carry out sampling according to GB/T 450. Sample treatment and test standard atmospheric condition shall be in accordance with GB/T 10739. 5.2 Quantification The quantity shall be determined according to GB/T 24328.5. Express the result in monolayer. 5.3 Brightness (whiteness) Brightness (whiteness) shall be determined according to GB/T 7974. 5.4 Portable fluorescent whitening agent Put the sample under ultraviolet lamp. Inspect whether there is fluorescence phenomenon at wave length of 254nm and 365nm. If the sample has no fluorescence phenomenon under ultraviolet lamp, then it can be determined that it does not contain portable fluorescent whitening agent. If the sample has fluorescence phenomenon, then determination of portable fluorescent whitening agent can be carried out according to Chapter 5 of GB/T 27741-2011. www.chinesestandard.net Page 7 of 12
