Foreword
This Standard was drafted as per the rules specified in GB/T 1.1-2009.
This Standard’s translation equivalently adopts ISO/TS 16181.2011 Footwear -
Critical Substances Potentially Present in Footwear and Footwear Components -
Determination of Phthalates in Footwear Materials.
This Standard made the following editorial changes.
--- The reagents in 3.2 were adjusted as per the order of ordinary reagent and
internal standard substance.
This Standard was proposed by China Light Industry Council.
This Standard shall be under the jurisdiction of National Technical Committee for
Standardization of Footwear (SAC/TC 305).
Drafting organizations of this Standard. China Leather and Footwear Research
Industry, Ritai Group Co., Ltd., Dongguan Xinhuwei Industry Co., Ltd., Zhejiang
Taizhou Xidebao Shoes Co., Ltd., and China Leather and Footwear Research
Industry (Jinjiang) Co., Ltd..

Footwear - Critical Substances Potentially Present in
Footwear and Footwear Components –
Determination of Phthalates in Footwear Materials
SAFETY PRECAUTIONS — Persons using this Technical Specification should
be familiar with normal laboratory practice. This Technical Specification does
not claim to address all of the safety problems, if any, associated with its use. It
is the responsibility of the user to establish appropriate safety and health
practices and to ensure compliance with any national regulator conditions.
IMPORTANT - It is absolutely essential that tests conducted according to this
Technical Specification be carried out by suitably trained staff.
1 Scope
This Technical Specification specifies a test method to determine the presence of
phthalate compounds. This test method is applicable to all types of footwear
materials.
NOTE 1.This test method can also be used to determine plasticizers other than those
listed in 3.2, subject to validation.
NOTE 2.ISO/TR 16178 defines which materials are concerned by this determination.
2 Principle
The aim of the method is to extract phthalates in footwear materials such as leather,
textile, polymer, coated materials or others. This method uses extraction apparatus
with n-hexane/acetone as solvent.
The total extractable phthalate plasticizer content is calculated by weight with gas
chromatography-mass spectrometry (GC-MS) detection to identify and quantify
individual phthalates.
