Interpretation Of National Standards For "Coating Clothing Moisture Resistance Technical Requirements"

GB/T 23317-2009 " Coated garments The technical standard of moisture resistance was formally implemented in January 1, 2010. Before that, China did not have national standards in this regard. The new standard mainly refers to the British BS6408:1983's "coating clothing moisture resistance technical requirements". standard It is suitable for garments, trousers, uniforms, work clothes, jackets, waterproof caps and other garments.

When designing and producing, manufacturers should pay special attention to the following requirements so as to ensure the production of qualified products.

1, the collar of uniforms, overalls, jackets and jackets should be of the same fabric as the clothes. The collar collar height is no less than 7cm, the collar collar height is at least 4cm, the bottom edge fastener is at least turned over 5mm, the hat can be separated from or permanently fixed with the clothes, but the minimum size should reach the following criteria (i.e., the seam size is 70cm from the top of the shoulder to the other side, the eye level is at the rear of the winding head, and the distance between the two hat sides is 48CM).

2. clothing If you have pockets or hanging loops, you must achieve the requirement of adhesion strength.

3, the jacket and jacket should be single breasted, and can be tightly attached to the neck. The design of the flap should prevent water from penetrating directly into the interior of the garment, while the work clothes require that the front Plaid should not be designed.

4, for the waist tightened pants, to design elastic belt or rope in the waist position, do not tighten the waist, should be designed into straps or overalls.

6, the waterproof cap must have a band to fasten on the chin position, and the cap of the waterproof cap should be made of two pieces of fabric before and after the center seam.

The standard specifies the strength of the joints, the peeling strength of the seams, the adhesion strength of the pockets, the strength of the hanging loops, etc., and the enterprise must meet the standard requirements when producing the products.

The main difference between the new GB and the BS6408:1983 standard of coating wetting technical requirements in Britain is:

1. Delete the terms and definitions of bat sleeves in the original standard.

2. The third chapter of the original standard was deleted, but its performance requirements for wet coating fabrics were directly quoted.

3, revised the minimum requirement of joint anti permeability.

4, delete the standard of the sixth chapter of the original standard and the symbol of the seventh chapter.

5, delete the original standard appendix B "joint strength test method: modify the use of BS2576", its test method refers to GB/T13773.1;

6, the national standard added appendix B, appendix C and appendix D.
