Criterios de prueba
The term "antimicrobial" is used if the activity against bacteria (cf. "antibacterial") has been successfully tested and additionally at least one of the two efficacy categories: mould fungi ("antimycotic") and/or surrogate viruses. The quality label is based on test reports with detailed results.
Hohenstein Laboratories tests the sample in accordance with the standard DIN EN 14119 "Testing of Textiles - Evaluation of the action of microfungi; method B2". The quality label is used to confirm that the test sample has an antimycotic activity against the test strains Aspergillus niger ATCC 6275 and Chaetomium globosum ATCC 6205. The inhibition of fungal growth must be ≥50 % for both test strains compared to a control material.
Hohenstein Laboratories tests the sample in accordance with the standard DIN EN ISO 846 "Plastics - Evaluation of the action of microorganisms; method B". The quality label is used to confirm that the test sample has an antimycotic activity against the test strains Aspergillus niger ATCC 6275, Penicillium pinophilum ATCC 36839, Paecilomyces variotii ATCC 18502, Trichoderma virens ATCC 9645 and Chaetomium globosum ATCC 6205 in the given test procedure of the standard test. The inhibition of fungal growth against the test strains must be ≥50 % compared to a control material.
The test sample is tested by Hohenstein Laboratories in a suspension test developed by Hohenstein (SOP-QM-11.HY.03.054 test method based on ISO 18184 or SOP-QM-11.HY.03 .057 test method based on ISO 21702) with the non-enveloped test virus bacteriophage MS 2 (ATCC 15597-B1) and the enveloped test virus Pseudomonas phage phi6 (DSM 21518) and a contact time of 2 or 24 hours (according to the specifications of ISO 18184 or ISO 21702). The antiviral activity of the test sample must be ≥ 3 log levels (≥ 99.9%).
The Hohenstein Laboratories are accredited by the DAkkS for all tests above.
