FZ/T 62011 Indoor Ornamental Textiles is divided into four parts:
——Part 1: Curtain;
——Part 2: Dinning Table Textiles;
——Part 3: Upholstery;
——Part 4: Interior Decoratives.
This part is the third part of FZ/T 62011.
This part is developed in accordance with the rules given in GB/T 1.1-2009.
This part replaces FZ/T 62011.3-2008 Indoor Ornamental Textiles - Part 3: Upholstery.
The following main changes have been made with respect to FZ/T 62011.3-2008 (the previous edition):
——The assessment indexes for first-grade products on breaking strength are improved (see 4.2; 4.2 in Edition 2008);
——The assessment requirements for first-grade products and qualified products on tearing strength are improved (see 4.2; 4.2 in Edition 2008);
——Assessment requirements on fuzzing and pilling and metal residues in inherent quality are added (see 4.2);
——Assessment requirements on deviation rate of dimension, skewness, bow and dyeing defect in appearance quality are added;
——Shape quality requirements in appearance quality are deleted (see 4.3; 4.3 in Edition 2008);
——Assessment requirements for embroidery quality in process quality are added (see 4.3);
——Assessment requirements for first-grade products and qualified products on color spot and stain are improved (see 4.3).
This part was proposed by China National Textile and Apparel Council.
This part is under the jurisdiction of National Technical Committee 302 on Household Textiles of Standardization Administration of China (SAC/TC 302).
Previous edition of this standard is as follows:
