Introduction
With the development of society and the improvement of people’s living standards, the chemical
safety of footwear has widely gained attention. As more critical substance in footwear and footwear
components are needed, many chemical test methods for critical substances have been developed.
However, there lacks a unified sample preparation method for chemical tests. Due to the complex
materials and structures used in footwear and the different ways in which critical substances exist,
the sample taken from footwear is often not sufficiently homogeneous to give a representative test
specimen. It is thus very difficult to develop a single technique of sampling that can be used in all
circumstances. However, if every material in an article of footwear were tested, it would be a large
amount of work and yield a large test fee. As an example, see Table 1, a common article of footwear
can cut into over 10 kinds of test specimen when carrying out tests for one chemical. So, a sampling
method is needed urgently to provide general rules for preparation of samples, which can reduce and
even prevent the inconsistency of sampling procedures between different laboratories and which can
provide a guarantee for the stability of test results.

lining are fully stuck by glue or other techniques and it is impossible to separate them), rubber boot upper (the
sock is fully dissolved in rubber), soling material (in injected sole footwear the insole can be fully dissolved in the
sole), foam with adhesive or foam with residues of adhesive, etc.

4.2 Component part designation
Figure 2 defines the different components of the footwear. Figure 2 shall be used to identify the
components present in the tested footwear (see ISO 19952 for definitions to components listed).
If needed, position terms can be used to further specify the designation of the part. Figures 3 and 4 can
be used as reference.
There are four main positions viewing from above: front, back, lateral and medial. For parts in between,
there are four more sub-positions (see Figure 3). There are two main positions viewing form lateral:
top and lower. For parts in between, there are 4 more sub-positions (see Figure 4).
If the decorative attachments cover more than 50 % of the upper area, as shown in Figure 1, consider
the decorative attachment as an upper.
4.3 Colour designation
The colour of test samples shall be determined according to the colour designation given in Annex A.
4.4 Material classification designation
Specify the material classification of each test sample. The material classification of each test sample
shall be in accordance with Annex C. For example, leather and fur, textile, polymer (including synthetic
materials, plastic etc.), rubber, foam, wood, metal and fibrous board, etc.
In certain cases, it is difficult for laboratories to easily identify the material of the component, for
example:
— Rubber, PU, plastic, foam should be termed as polymers.
— Natural and synthetic fibres should be termed as textiles.
NOTE The material classification can be completed by additional information:
— Leather can be further classified into bovine, sheep, goat, coated bovine, bovine suede, split bovine, etc.
— Textile can be further classified into cotton, silk, polyamide, polyester, fibre blending, etc.
4.5 Useful information designation
For test samples, the information below shall be specified:
— component in contact with the skin or component not in contact with the skin;
— accessory;
— if the component is covered by glue(s);
— accessible component or inaccessible component.

rules for preparation of samples, which can reduce and even prevent the inconsistency sampling
procedure in different laboratories and can provide a guarantee for the stability of test results.
This standard intends to specify terms and definitions, instruction of procedures and some special
examples etc., to give a rough specification for sampling shoes when carrying out chemical tests, and
can be acceptable in meeting the common types of problem encountered in sampling for the assessment
of footwear critical substance content.
The sampling procedures described are designed to allow concurrent chemical testing for footwear.
