ISO 16187 pdf download Footwear and footwear components — Test method to assess antibacterial activity
This International Standard specifies quantitative test methods to evaluate the antibacterial activity offootwear and components.
This International Standard is applicable to all types of footwear and components employing non-diffusing antibacterial treatments.

3 Terms and definitions
For the purposes ofthis document, the terms and definitions given in ISO 19952 and the following apply.
31
antibacterialactivityefficacy of a material or finish used to prevent or mitigate the growth of bacteria, to reduce the numberof bacteria or to kill bacteria
3.2
control samplematerial identical to the test material but without antibacterial treatment
Safety
Handling of microorganisms which are potentially hazardous requires a high degree of technicacompetence and can be subject to current national legislation and regulations. Only personnel trainedin microbiological techniques should carry out such tests. Codes of practice for disinfection, sterilizationand personal hygiene shall be strictly observed
NOTEltis recommended that workers consultIEC 60068-2-10,appendixA”Danger to personnel”andISO 7218.
