FZ/T 93048 Needles for needle loom is to be published in several parts, and the following parts are planned to be published currently: ——Part 1: Felting needles; ——Part 2: Fork needles; ——Part 3: Conical felting needle; … This is Part 1 of FZ/T 93048. This standard is developed in accordance with the rules given in GB/T 1.1-2009. This part replaces FZ/T 93048-2010 Felting needles and the following main technical changes have been made with respect to FZ/T 93048-2010: ——Four terms and definitions, including "barb distances on same edge", have been deleted (see Clause 2 herein; Clause 2 of 2010 Edition); ——The parameters of felting needles with code of 9 and 10 have been added, the description of the working part section height of the felting needles with non-regular triangular section has been added, and the parameters of individual felting needles have been adjusted (see Table 1 herein; Table 1 of the 2010 Edition); ——The specification for felting needles with nominal length of 80 mm has been added (see Table 2 herein; Table 2 of the 2010 Edition); ——The technical requirements of felting needles have been changed into "characteristics" for description (see 4.2 herein, Clause 4 of 2010 Edition); ——The representation method of the number of edge barbs of special felting needles has been added (see 5.1); ——The contents of test methods, inspection rules and marking, packaging, transportation, and storage have been deleted (see Clauses 5, 6, and 7 of 2010 Edition). ——The editorial changes have been made. This part was proposed by the China National Textile and Apparel Council. This part is under the jurisdiction of the Subcommittee on Nonwoven Machinery of the National Technical Committee on Textile Machinery and Accessory of Standardization Administration of Chin (SAC/TC 215/SC 3). The previous editions of this part are as follows: ——FZ/T 93048-1998, FZ/T 93048-2010. Needles for needle loom — Part 1: Felting needles 1 Scope This part of FZ/T 93048 specifies the terms and definitions, classification and basic structure, dimensions and characteristics, and marking of felting needles.
