Main Function & Applications
AATCC 15 is the American colour-fastness-to-perspiration method, and it is not interchangeable with ISO 105-E04. It specifies an acid perspiration solution only, there is no alkaline run, and its formulation and conditioning differ from the ISO one, so a result obtained under one method cannot be reported against the other. In practice a European manufacturer exporting to the United States is asked for both: ISO 105-E04 for the EU file and AATCC 15 for the American buyer or retailer specification. Order both and the same laboratory runs both campaigns without reformulating: the ISO 105-E04 matched pair, and this single acid solution at the AATCC composition and pH.
User Sectors & Laboratories
- Textile testing labs & CROs
- Fashion, footwear & leather brands
- Dye & colorant makers
- Textile schools & research
Good to know
If your specification cites both AATCC 15 and ISO 105-E04, you need two different products: they differ in pH, in chloride and histidine content, and ISO 105-E04 additionally requires an alkaline solution that AATCC 15 does not use.
