This standard was proposed by China National Textile and Apparel Council.
This standard is under the jurisdiction of National Technical Committee on Garments of Standardization Administration of China (SAC/TC 219).
The previous edition of this standard is as follows:
—GB/T 22704-2008.
Introduction
The need for exploration and challenge, and the unawareness of cause and effect drive children to use items in new and different ways, they are therefore substantially less cautious than adults in relation to hazards.
This standard is intended for use at all stages of the clothing supply chain, including use by designers, specifiers and manufacturers of children’s clothing to improve the mechanical safety in the design and manufacture of children's clothing. It is also intended to be used by importers, distributors and retailers to assist them in the selection of clothing that does not present a mechanical hazard.
Code of practice for the design and manufacture of children's clothing to promote mechanical safety
1 Scope
This standard specifies terms and definitions, mechanical hazards and risks, risk assessment, garment design, materials and construction, manufacture, inspection and testing of materials and garment, packaging, tagging and display for the design and manufacture of clothing for children up to 14 years of age.
This standard is applicable to the design and manufacture of clothing for children up to 14 years of age, and should be adopted from the design stage.
This standard does not apply to:
—child care articles, such as bibs, nappies and soother holders;
—footwear, such as boots and shoes;
—toys and other items sold with the clothing.
—clothing with features designed to cater for children with special needs.

4 Mechanical hazards and associated risks
4.1 Ischemic injury
Ischemic injuries can be caused by restricted blood circulation due to loose or untrimmed threads on the foot or hand area of garments becoming wrapped around fingers or toes, or by entrapment of fingers or toes in open fabrics (e.g. crochet) or in fabrics with long float stitches. Some large and hard holes in elements such as buttons, snap fasteners, eyelets and zippers may entrap the tongue or fingers. This causes a tourniquet effect, thus restricting the blood circulation. This is a particular concern in babywear design for babies and infants aged up to 12 months as the source of distress cannot be communicated by the baby and might go undetected for some time. In addition, areas of skin or parts of the genitalia can protrude through a mesh fabric used as a lining for swimming trunks. This poses a risk of entrapment in the mesh leading to ischemic injury. Elasticated cuffs can also cause a reduction in blood flow to the hands or feet if the elastic is too tight or too strong; this is a particular concern in babywear design for babies and infants aged up to 12 months.
4.2 Entrapment in a slide fastener
All boys’ trousers that have a slide fastener present a risk of entrapment of the penis in the fastener. Although reducing the use of slide fasteners can eliminate such risk, this is not a long-term and practical resolution. Manufacturers should make more technological innovations to improve the mechanical safety of children's clothing.
4.3 Injuries from sharp objects
Injuries to children can be caused by clothing which contains sharp objects. The severity of the injury can range from a scratch or irritation to a more serious piercing injury and cut injury. Injuries can be caused by components with accessible sharp points, which are sometimes found on buttons, slide fasteners and decorative features, or by accessible sharp edges which are produced through the deterioration of components during the wear and aftercare lifecycle of the garment. Pins, staples and other sharp objects used in the manufacture and packaging of clothing can also cause serious injury if they are left in the garment.
4.4 Choking and aspiration
Buttons, toggles, motifs and many other garment attachments (including rubber and soft plastics items, such as badges) can be a potential hazard, particularly to babies and infants, if the item becomes detached from the garment. As young children are known to place such items in their mouth, and might also insert them into their nose or ears, any foreign object found in a child’s garment can present a risk of either choking or aspiration. Stones left as a residue from a stone-washing process can present the same risks. Aspiration (where items are inhaled via the mouth or nose) is possible if detached parts are sufficiently small to pass into the trachea and lungs, for example beads, diamantés and sequins. Often these items might not be detected, as their chemical nature means they are unlikely to be identified by X-ray. The foreign body can cause toxic shock or lead to an infection, the source of which might not be readily identified. This can result in rapid and unexplained weight loss requiring hospitalization. This is rarely happened.
4.5 Swallowing
In most cases a detached item that has been swallowed will pass into the stomach and should eventually pass through the body with food without causing harm. Notable exceptions are sharp objects, button batteries and magnets.
