——Some references in "Normative references" have been updated (see Clause 2 hereof; Clause 2 of Edition 2011);
——The definition of top sheet run-off has been deleted, and the definitions of absorption speed, top sheet SAP residual and foreign material have been added (see Clause 3 hereof; Clause 3 of Edition 2011);
——The classification by uroclepsia degree and wearable mode has been added (see Clause 4 hereof; Clause 4 of Edition 2011);
——The full-length deviation and full-width deviation have been deleted, and the top sheet run-off index has been replaced by absorption speed (see Clause 5 hereof; Clause 5 of Edition 2011);
——The top sheet SAP residual, foreign material, absorption ratio, saturated absorption, formaldehyde content and migratable fluorescent substance indexes have been added (see 5.1 and 5.2 hereof);
——The requirements for applicable maximum hip circumference and waist circumference have been added (see 5.6 hereof);
——The determination method of rewet and leakage has been modified, and the determination method of absorption speed has been added (see Annex A hereof; Annex A of Edition 2011);
——The determination method of pH has been modified (see Annex B; Annex B of Edition 2011);
——The determination methods of foreign material and migratable fluorescent substance have been added (see Annexes C and D hereof).
This part was proposed by China National Light Industry Council.
This part is under the jurisdiction of the National Technical Committee on Paper Industry of Standardization Administration of China (SAC/TC 141).
