ISO/TC 148 - Sewing machines

ISO 10821:2005 identifies hazards and specifies safety requirements applicable to sewing machines, sewing units and sewing systems designed for professional (industrial, commercial or laboratory) use in industries including the clothing and footwear, leather goods, shirts and blousery, hosiery and knitwear, lingerie, glove, upholstery and packaging industries, and in shoe repair. The use of such machines in other industries could give rise to hazards not considered. It is not applicable to shoe bottom stitching machines, large shuttle embroidery machines in accordance with ISO 11111 or household sewing machines in accordance with IEC 60335-2-28.

ISO 8239 specifies the fitting dimensions of needles and needle holders. It defines general terms for sewing machine needles and specifies the tolerances for their fit in the needle holder. In addition to the rangers of dimensions for the nominal shank diameter and the length from butt to eye, ISO 8239 also indicates the preferred combinations of these two dimensions. In order to ensure the interchangeability and to reduce the variety of needles these should serve as a guide when designing new sewing machines and/or sewing machine needles.

Establishes a numerical classification of sewing machines. Gives the classification criteria the characteristics of which are tabulated in tables 1 to 7 respectively.

The directional stability (drift) is caused by irregularities of the feed mechanism as an individual machine funktion, without using a sewing thread. The method is applicable to motor-operated household sewing machines, but it may also be possible to apply it to hand- or treadle-operated machines. Includes additionally to definitions, principle, preparation of the sewing machine, prodcedure, expression of results and test report an annex which specifies material and apparatus.

The method is applicable to motor-operated household sewing machines, but it may also be possible to apply it to hand- or treadle-operated machines. Includes additionally to definition, principle, preparation of the sewing machine, procedure, expression of results and test report an annex which specifies material and apparatus.

The method determines the stitch length at constant setting of the stitch length setting control after various adjustments and is applicable to motor-operated household sewing machines, but it may also be possible to apply it to hand- or treadle- operated machines. Includes additionally to principle, preparation of the sewing machine, procedure, expression of results and test report an annex which specifies material and apparatus.

The method for the determination of the swing capacity is applicable to motor-operated household sewing machines, but it may also be possible to apply it to hand- or treadle-operated machines. Includes additionally to definition, principle, preparation of the sewing machine, procedure, expression of results and test report an annex which specifies material and apparatus.

Specifies a method of test for determining the variation of needle thread tension at given positions of the tension regulator. The method is applicable to motor-operated household sewing machines, but it may also be possible to apply it to hand- or treadle-operated machines. Includes additionally to principle, material and apparatus, procedure, expression of results and test report an annex which specifies the cotton thread.
