ICS 61:060 CCSY78 National Standards of People's Republic of China Replace GB/T 32440-2015 Chemical test methods for footwear Determination of phthalates Part 1: Solvent Extraction Method Part 1: Solventextraction solventextraction,MOD) Published on 2023-12-28 and implemented on 2024-07-01 State Administration for Market Regulation Released by the National Standardization Administration Committee ForewordThis document complies with the provisions of GB/T 1:1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" Drafting: This document is Part 1 of GB/T 32440 "Chemical Test Methods for Footwear - Determination of Phthalates": GB/T 32440 The following sections have been published: ---Part 1: Solvent extraction method: This document replaces GB/T 32440-2015 "Determination of limited substances phthalates present in footwear and footwear parts:" "Standard", compared with GB/T 32440-2015, in addition to structural adjustments and editorial changes, the main technical changes are as follows: a) Changed the scope (see Chapter 1, Chapter 1 of the:2015 edition); b) Added terms and definitions (see Chapter 3); c) The principle has been changed (see Chapter 4, Chapter 2 of the:2015 edition); d) Changed the requirements for reagents (see Chapter 5, 3:2 and 5:1 of the:2015 edition); e) The requirements for instruments and equipment have been changed (see Chapter 6, 3:1 of the:2015 edition); f) Changed the sampling requirements (see Chapter 7, Chapter 4 of the:2015 edition); g) The test procedures have been changed (see Chapter 8, Chapter 5 of the:2015 edition); h) Changed the expression of results and added requirements for calibration curves (see Chapter 9, 5:3 of the:2015 edition); i) The requirements for test reports have been changed (see Chapter 10, Chapter 6 of the:2015 edition): This document is modified to adopt ISO 16181-1:2021 "Footwear, footwear and footwear parts, limited substances phthalates" Determination Part 1: Solvent Extraction Method: Compared with ISO 16181-1:2021, this document has made the following structural adjustments: ---Adjust "Explanation of analysis results of different methods" in ISO 16181-1:2021 Chapter 4 Principles to Chapter 1 (see Chapter 1 and Chapter 1 Chapter 4); ---Adjust the suspended section of Chapter 6 in ISO 16181-1:2021 to 6:1, and then the number of the same level section will be automatically extended (see Chapter 6); ---Appendix C, Appendix D and Appendix F respectively correspond to Appendix F, Appendix C and Appendix D in ISO 16181-1:2021: The technical differences between this document and ISO 16181-1:2021 and their reasons are as follows: ---Replaced ISO 4787:2010 (see Chapter 6) with the normatively cited GB/T 12810-2021 to adapt to my country's technical conditions parts to increase operability; --- Added the judgment of validity of polyvinyl chloride sample test results (see 8:1:2) to improve the operability of judgment and eliminate ambiguity: The following editorial changes have been made to this document: ---In order to coordinate with the existing standards, the name of the standard is changed to "Chemical Test Methods for Footwear - Determination of Phthalates - Part 1 Points: Solvent Extraction Method"; ---Replaced ISO /T R16178:2012 with the informative ISO 21061:2021 (see Chapter 1); ---Change the expression of Teflon to polytetrafluoroethylene (see 6:3, 8:1:1 and 8:1:2); ---There is an error in formula (2), and the formula for calculating the concentration of each phthalate ester in the sample solution has been changed (see 9:1): Please note that some content in this document may be subject to patents: The publisher of this document assumes no responsibility for identifying patents: This document is proposed by China Light Industry Federation: This document is under the jurisdiction of the National Shoemaking Standardization Technical Committee (SAC/TC305): This document was drafted by: Guangzhou Inspection, Testing and Certification Group Co:, Ltd:, Lirong Shoes (Shenzhen) Co:, Ltd:, Guangzhou Jiatu Technology Co:, Ltd: Co:, Ltd:, Taizhou Zuyou Sporting Goods Co:, Ltd:, Wenling Dongyu Shoe Materials Co:, Ltd:, Fujian Shishi Fusheng Shoes Co:, Ltd:, SGS Standard Technical Services (Shanghai) Co:, Ltd:, China Leather and Shoemaking Research Institute Co:, Ltd:, China Light Inspection and Certification Co:, Ltd: The main drafters of this document: Yang Fengbo, Ren Lei, Feng Weizhao, Cai Jianyue, Jiang Liangfu, Zhang Xiaoqi, Su Jian, Liang Jiyu, Li Jia, Li Wenjie: The previous versions of this document and the documents it replaces are as follows: ---First published as GB/T 32440-2015 in:2015;IntroductionPhthalates are the collective name for esters formed from phthalic acid: Phthalates are mainly used in polyvinyl chloride materials to act as plasticizers: use: After phthalates are absorbed into the body, they interfere with the endocrine system and reproductive system, which may cause potential danger to the human body: The content of phthalates in shoes has increasingly become a focus of consumer concern: GB/T 32440 "Footwear Chemical Test Methods Phthalates "Determination of Formate Esters" aims to provide a basis for the determination of phthalates present in footwear and footwear components and is intended to consist of two parts: ---Part 1: Solvent extraction method: Solvent extraction aimed at determining the phthalate content present in footwear and footwear components: Adopt methods and establish operable, traceable and verifiable procedures: ---Part 2: Non-solvent extraction method: The purpose is to determine the content of phthalates present in footwear and footwear parts: Agent extraction method and establish operable, traceable and verifiable procedures: Both methods are suitable for the determination of phthalates present in certain concentrations in footwear and footwear components: Compatible with non-solvent extraction methods Compared with solvent extraction method, it has higher accuracy and wider application range: Chemical test methods for footwear Determination of phthalates Part 1: Solvent Extraction Method Warning---The use of this document may involve hazardous materials, operations, and equipment: It is not intended to address all security issues associated with its use: safety or environmental issues: Users of this document are responsible for taking appropriate measures to ensure the safety and health of personnel and the environment before applying this document: health, and determine the applicability of regulatory limits:1 ScopeThis document describes methods for the qualitative and quantitative detection of phthalates (Appendix A) in footwear and footwear components: This document applies to the determination of phthalates in footwear and footwear components: Note 1: Appendix C of ISO 21061:2021 or CEN/T R16417 gives a list of relevant materials: Note 2: In addition to the phthalates listed in Appendix A, this test method is verified before being used for the determination of other phthalates: Compared with ISO 16181-2, the analysis results of these two methods have similar trends but are not necessarily identical: Therefore, in dispute In this case, this document takes precedence over ISO 16181-2:2 Normative reference documentsThe contents of the following documents constitute essential provisions of this document through normative references in the text: Among them, the dated quotations For undated referenced documents, only the version corresponding to that date applies to this document;
