Results of testing by interlaboratory comparison concerning determination of fabric propensity to surface fuzzing and to pilling are presented in this article. Fuzzing and pilling were tested according to: 1. PN-EN ISO 12945-1:2002 "Textiles. Determination of fabric propensity to surface fuzzing and to pilling. Part 1: Pilling box method." 2. PN-EN ISO 12945-2:2002 "Textiles. Determination of fabric propensity to surface fuzzing and to pilling. Part 2: Modified Martindale method." Ten Laboratories took part in those tests: eight testing laboratories accredited by Polish Centre for Accreditation and two industrial laboratories.
