4 Test methods associated to the criteria
NOTE The uncertainty of measurement for each test method described in this European Standard can be assessed
according to the methods described ENV 13005 or ISO 5725-2.
4.1 Determination of total heavy metals content
4.1.1 General
The total concentration of heavy metals in a product is considered as a relevant criterion regarding the end of life disposal. This test method identifies the main chemicals of potential hazard which may contaminate the environment after disposal or incineration.
There shall be no Arsenic, Cadmium and Lead in the materials used for the product assembly or in the final product. Presence of heavy metals shall be established by either:
testing the materials individually; or
testing the upper and lower components of the shoe as composite groups of materials.
4.1.2 Preparation of the samples
4.1.2.1 Testing the materials for the product assembly
Test each material individually.
Each material is ground according to EN ISO 4044 or a similar test method.
NOTE Textile materials do not need to be ground.
4.1.2.2 Testing the final product
Separate the upper and the lower components of the footwear.
Fully grind each group of components separately according to EN ISO 4044 or a similar test method.
NOTE Only a full grinding of the test specimen will ensure the reproducibility of the test results.
4.1.3 Reagents
WARNING—Violent reactions may be produced with perchloric acid (HCIO4) on an organic matrix.
4.1.3.1 H2S04, 96 % (mass fraction).
4.1.3.2 HNO3, 65% (mass fraction).
4.1.3.3 HCIO4, 65 % (mass fraction).
4.1.3.4 HCI, 36 % (mass fraction).
4.1.3.5 Demineralised water.
4.1.4 Apparatus and materials
Standard laboratory apparatus and glassware, together with the following:
4.1.4.1 A suitable heating device (for the acid digestion only).
4.1.4.2 Volumetric flask, of 100 ml.
4.1.4.3 Filter paper of 0,45 urn mesh size.
4.1.4.4 MIcrowave reactor (for the microwave digestion on’y), capable of working at maximum
100 bars (or 1 450 psi).
4.1.5 Digestion
4.1.5.1 Method A — acid digestion
Prepare, according to 4.1.2, a test piece of (0,500 ± 0,005) g of ground sample. The digestion given in
EN 1122:2001, 6.3.2, method B is to be used.
4.1.5.2 Method B — acid digestion
Prepare, according to 4.1.2, a test piece of (1,000 ± 0,005) g of ground sample. The digestion given in EN ISO 17072-2:2011, 6.5.1 is to be used.BS EN 14602 pdf free download.
