Test criteria.

The practice-oriented testing is based on a standardized model of human skin flora, in which germ colonization, topography and milieu properties of healthy skin are simulated. 

The effect of the samples against germs is analyzed quantitatively on the artificial skin/skin flora over 18 hours and assessed against internal controls or an identical material without antimicrobial activity. If no significant germ reduction appears within this wearing/exposure period, the textile is regarded as “safe” with respect to effects towards the human skin flora.

Supplementary testing for antibacterial effectiveness according to DIN EN ISO 20743 is a prerequisite for obtaining the label.
