This document is for reference by manufacturers, distributors, shopping malls, e-commerce units, inspection and regulatory agencies, consumers and other interested parties in the use of GB 31701-2015.
2 Interpretation of provisions
[Provision]
1 Scope
This standard specifies the safety technical requirements, test methods, and inspection rules of the textile products for infants and children.
[Interpretation]
This paragraph is a brief introduction to GB 31701-2015, which summarizes the main contents of the standard in three aspects: safety technical requirements, test methods, and inspection rules.
[Provision]
This standard is applicable to the textile products for infants and children sold in China.
Note: Fabric and plush toys, fabric handicrafts, disposable sanitary products, bags, handbags and knapsacks, umbrellas, carpets, professional sportswear, etc. do not fall within the scope of this standard.
[Interpretation]
This paragraph clarifies the scope and objects of application of GB 31701-2015:
——"Sold in China" means that the products sold in China fall within the scope of the standard, regardless of whether they are produced in China or produced abroad and imported into China, including products sold in shopping malls, sold on the Internet, purchased by groups, and gifted or donated.
——"Textile products for infants and children" refer to textile products for infants aged 36 months and below to wear or use, and those for children aged over 3 through 14 years to wear or use. The textile products for children are subdivided into two age groups. See the table below for details:
Product category Age Applicable body height (reference)
Textile products for infants 0 < age ≤ 36 months Body height ≤ 100cm
Textile products for children 3 years < age < 7 years 100cm < body height ≤ 130cm
7 years ≤ age ≤ 14 years Girls: 130cm < body height ≤ 155cm
Boys: 130cm < body height ≤ 160cm
The "Note" under this paragraph lists products that do not fall within the scope of GB 31701-2015, mainly including products in following three situations: 1) products that have mandatory national standards in other industries, such as fabric and plush toys and disposable sanitary products; 2) textile products with special uses, such as fabric handicrafts and professional sportswear; 3) products of light industry and other fields, such as bags, handbags and knapsacks, umbrellas, carpets, and tents. It is impossible to list all the inapplicable products in the "Note". Users of the standard may judge whether the products fall within the scope of application of GB 31701-2015 according to the tips given by the listed products.
[Provision]
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
[Interpretation]
This paragraph is a description of the standards referenced in GB 31701-2015. Reference to standards means reference to one or more standard numbers or clause/subclause numbers in place of its/their detailed contents in the standard. This is to avoid repetition of the prescribed contents, thus reducing the length of the standard and avoiding errors such as contradictions or inconsistencies caused by repeated preparation of the prescribed contents. Therefore, by referencing to standards, we can not only ensure the scientific and advanced nature of the standard, but also achieve the coordination and matching between standards. There are the following concepts to be clarified:
——"Normative reference" means that after being referenced to, these standard provisions become an integral part of GB 31701-2015. Standards for reference only are listed in the "Bibliography".
——"Dated reference" means that the chronological number of the referenced standard is given in addition to the file code and serial number. Dating implies that the version with the date shall be applied and that subsequent new revision, if any, is not applicable to the standard.
——"Undated reference" means that only the file code and serial number of the referenced standard is given, without a chronological number. For undated references, the latest edition of the referenced document (including any amendments) applies regardless of how it has been updated.
