3. Terms and definitions
The following terms and definitions are applicable to this Standard.
3.1 Textile products
The products of which the main materials comprise of natural and chemical fibers; that
are processed by using procedures such as reeling, knitting, and dyeing, combined
with stitching and compounding processes. Examples include yarn, textile and their
finished products.
3.2 General safety specification
The fundamental specification that is required to ensure that fabric products are not
harmful to human health.
3.3 Textile products for infants
The textile products that are worn or used by infants at/below 36 months of age.
3.4 Textile products with direct contact to skin
The textile products with large areas in direct contact with human skin when worn or
used.
3.5 Textile products without direct contact to skin
The textile products with little or no area in direct contact with human skin when worn
or used.
4. Product categorization
4.1 Products are sorted by end use into three categories.
• Textile products for infants
• Textile products with direct contact to skin
• Textile products without direct contact to skin
4.2 Products that can only be used after further processing by the customer (such as.
7. Inspection rules
7.1 Representative samples shall be randomly selected from every batch of products
by category and color. One sample is then selected for each different color within
every category.
7.2 Individual goods shall be sampled at a minimum distance of 2 m away from one
end, and the sample shall be a whole piece with a length no less than 0.5 m; sampling
of garments or other products shall satisfy the requirements of the determination
process.
7.3 Following sample selection, the goods shall be sealed such that they are airproof.
No action shall be taken. The relevant sampling technique can be found in the
sampling manual in Appendix D.
7.4 An assessment shall be performed by product category in accordance with Table
1. If the results of the product determination all satisfy the corresponding requirements
in Table 1 (all components of products with two or more components shall satisfy the
corresponding requirements in Table 1), these samples will then conform to the
general safety technical specifications; otherwise they will fail to do so. No
determination process is required for small components with a total weight of less
than 1% of the whole product that come into contact with skin either directly or
non-directly.
7.5 If the selected samples are all conformant, the batch of products shall be
determined to be conformant with the general safety technical specifications. In the
event of any non-conformant samples, the product category or color represented by
the sample shall be determined as non-conformant.
