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):

Introduction
Phthalates 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:

1 Scope
This 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:
