GB/T 29292-2024 Footwear - Guidelines for the management and control of key chemicals in footwear and footwear components 1 Scope This document defines the terms and definitions of key limited chemicals in footwear and footwear components, and proves a summary table (types of limited chemicals, types of limited chemicals, materials with possible limited chemicals, reference test methods, etc.). This document is applicable to the management and control of key chemicals in footwear and footwear components. 2 Normative references There are no normative references in this document. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 allergen substance that is capable of inducing an allergic reaction 3.2 allergy immunologically mediated response to certain specific substances (allergens) Note: Type-1 allergy is mediated by lgE antibodies, can cause asthma, rhinitis, urticaria. Type-4 allergy is mediated by T-cells, can cause dermatitis 3.3 critical substances chemical substance that can be found in footwear or footwear components and found to have or may have an effect on the wearer and/or environmental impact due to its chemical reactivity Note 1: The effects caused by critical substances vary. It can be carcinogenic or mutagenic effects, allergy, reaction to toxics, etc. Note 2: This document provides the available information at the time of publication. However, as the laws and regulations may change, the users of this document shall check for the update themselves. 4 Category of limited substances According to the confirmation degree of the harm of limited substances to users, limited substances are divided into the following four categories. - critical substances category 1: substances with proven dangerous effect on the wearer Note 1: These substances are widely restricted by national laws, regulations and standard in several countries or regions. - critical substances category 2: substances with potential dangerous effect on the wearer Note 2: These substances are restricted by national laws, regulations and standards in a limited number of countries or regions. - critical substances category 3: substances that are highly suspected to have an effect on the wearer Note 3: These substances might not be restricted by regulation but they are frequently requested by the market stakeholders. - critical substances category 4: substances that are suspected to have an effect on the wearer Note 4: These substances might not be restricted by regulation. Substances known to have an allergenic effect on the wearer are included in category 4 for reference. 5 Presence of chemicals in footwear materials A number of chemicals are present in footwear materials. Table 1 lists the following: a) The possible materials potentially used in footwear are given in GB/T 45063-2024, Annex C. b) a list of critical chemicals, (see Annex A for information); c) reference test methods that can prove the presence of limited substances and can be used to quantify them; d) the category of limited substances used to assess the potential risks of the limited substances (see Clause 4). For composite materials, the tests should be conducted on the entire component. Table 1 Critical chemicals potentially present in footwear and footwear components (continued) S.N.
