Test only the components or material which are claimed to be antibacterial. If the whole footwear is claimed as antibacterial, major components, including upper, lining, insole, insock, outsole shall be tested separately.
In the case where only one material of a component is claimed to be antibacterial, it shall be tested separately, if possible. Otherwise, the whole component shall be tested.
The area of test specimen should be about 500 mm2. For test method A (see Annex A), the area of test specimen shall have a thickness of less than 2,0 mm. The area and the weight shall be reported in the test report. If a larger test specimen is used then the volume of bacterial suspension should be increased proportionally.
If it is impossible to lower the thickness of the test specimen (for example, components are thicker and cannot be separated or cut without changing critical properties like surface morphology which may affect how the bacteria interact with the surface), the thickness shall be indicated in the test report.
At least six test specimens shall be taken for each material or component and for each test strain.
Pre-treatment of the test specimen is optional and should only be conducted if necessary due to high bioburden (contamination etc).
If sterilization methods are applied, they shall be reported in detail, and shall not affect the antibacterial properties or the material itself.
NOTE The test and control sample can be sterilized with the autoclave (5.4) at (121±2) °C and 103 kPa for 15 min, or with ultraviolet rays [ultraviolet lamp (5.6), 30 W, away from the sample 300 mm, each side for one hour respectively] or other suitable sterilizing methods.
Table 1 lists the circumstances under which each test method should be applied.
Test method A (see Annex A) should be used only for absorbent single material. Test method B (see Annex B) should be used only for non-absorbent single materials. Test method C (see Annex C) can be applied to both absorbent and non-absorbent materials or combinations.
NOTE For single material, method A and B are preferred.ISO 16187 pdf download.
