Criterios de prueba
Tests are based on product specification.
- Efficacy against sweat odor producing bacteria
Based on the standard test method, DIN EN ISO 20743, the antibacterial activity is determined against the skin-specific microbes Staphylococcus and Corynebacterium after 18 hours of incubation.
Odor release and retention textiles
- Release of sweat odor
A special sweat odor simulate (artificial sweat) is applied on the sample. The sweat odor intensity is assessed by trained odor panellists according to VDI 3882.
- Binding capacity for sweat odor molecules
A radioactively labelled lead substance of odorous sweat on the fabric is quantified with scintillation measurement.
Products that optimize odor redution
- Sweat odor field test
Samples are worn by a group of test persons in an application-specific activity (e.g. sports, work). Sweat odor intensity is then evaluated by trained panellists using an olfactometric sampling device. The field test proves an anti-sweat-odor effect from the user’s point of view.
