This document specifies testing methods for the determination of the antiviral activity of the textile products against specified viruses. Due to the individual sensitivities, the results of one test virus cannot be transposed to other viruses.<\/p>\n

The textile products include woven and knitted fabrics, fibres, yarns, braids, etc.<\/p>\n
