Annotation of standard text ÖNORM EN ISO 20743 :

Dieses Dokument legt quantitative Prüfverfahren zur Bestimmung der antibakteriellen Wirkung aller antibakteriell behandelten textilen Erzeugnisse, einschließlich Vliesstoffe, fest. Dieses Dokument ist anwendbar auf alle textilen Erzeugnisse, einschließlich Stoffe, Wattierung, Garn und Materialien für Bekleidung, Bettwäsche, Heimtextilien sowie verschiedene Waren, ungeachtet des Typs des verwendeten antibakteriellen Wirkstoffs (organisch, anorganisch, natürlich oder künstlich) oder des Anwendungsverfahrens (eingebaut, Nachbehandlung oder Pfropfen). Dieses Dokument behandelt drei Inokulationsverfahren zur Bestimmung der antibakteriellen Wirkung: a) Absorptionsverfahren (ein Bewertungsverfahren, bei dem die bakterielle Prüfsuspension direkt auf Proben geimpft wird); b) Übertragungsverfahren (ein Bewertungsverfahren, bei dem Prüfbakterien auf eine Agarplatte aufgebracht und auf Proben übertragen werden); c) Stempelverfahren (ein Bewertungsverfahren, bei dem Prüfbakterien auf ein Filter aufgebracht und auf Proben gestempelt werden). Dieses Dokument legt auch das Kolonie-Plattenzählverfahren und das Adenosintriphosphat-(ATP)-Lumineszenzverfahren zum Messen der Bakterienzahl fest.
