Textiles - Determination of antibacterial activity of antibacterial finished products (ISO 20743:2007)
ISO 20743:2007 specifies quantitative test methods to determine the antibacterial activity of antibacterial finished textile products including nonwovens.
ISO 20743:2007 is applicable to all textile products, including cloth, wadding, thread and material for clothing, home furnishings and miscellaneous goods regardless of the type of antibacterial agent used (organic, inorganic, natural or man-made) or the method of application (built-in, after-treatment or grafting).
Based on the intended application and on the environment in which the textile product is to be used, the user can select the most suitable of the following three methods on determination of antibacterial activity: a) absorption method (an evaluation method in which test bacterial suspension is inoculated directly onto samples); b) transfer method (an evaluation method in which test bacteria are placed on an agar plate and transferred onto samples); c) printing method (an evaluation method in which test bacteria are placed on a filter and printed onto samples).
The colony plate count method and the ATP (Adenosine Tri-phosphate) luminescence method are also specified for measuring the enumeration of bacteria.
Textilien - Bestimmung der antibakteriellen Wirkung antibakteriell behandelter Erzeugnisse (ISO 20743:2007)
Die vorliegende Internationale Norm legt quantitative Prüfverfahren zur Bestimmung der antibakteriellen Wirkung antibakteriell behandelter textiler Erzeugnisse, einschließlich Vliesstoffe fest.
Diese Internationale Norm ist anwendbar auf alle textilen Erzeugnisse, einschließlich Stoffe, Wattierung, Garn und Materialien für Bekleidung, Heimtextilien sowie verschiedene Waren, ungeachtet des Typs des verwendeten antibakteriellen Mittels (organisch, anorganisch, natürlich oder künstlich) oder des Anwendungs¬verfahrens (eingebaut, Nachbehandlung oder Pfropfen).
Auf der Grundlage der beabsichtigten Anwendung und der Umgebung, für die das textile Erzeugnis zu verwenden ist, kann der Anwender aus den folgenden drei Verfahren zur Bestimmung der antibakteriellen Wirkung das geeignetste auswählen.
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).
Das Kolonie-Plattenzählverfahren und das ATP-Lumineszenzverfahren (ATP = Adenosintriphosphat) werden auch zum Messen der Bakterienzahl festgelegt.
Textiles - Détermination de l'activité antibactérienne des produits finis antibactériens (ISO 20743:2007)
L'ISO 20743:2007 spécifie des méthodes d'essai quantitatives permettant de déterminer l'activité antibactérienne des produits textiles finis antibactériens, y compris les non-tissés.
L'ISO 20743:2007 s'applique à tous les produits textiles, y compris le tissu, le rembourrage, le fil et les matériaux utilisés dans la confection de vêtements, de tissus d'ameublements et d'articles divers, quel que soit le type d'agent antibactérien utilisé (organique, inorganique, naturel ou synthétique) ou quelle que soit la méthode d'application (intégration, post-traitement ou greffage).
Tenant compte de l'application prévue et de l'environnement dans lequel le produit textile est destiné à être utilisé, l'utilisateur peut choisir la plus adaptée des trois méthodes suivantes de détermination de l'activité antibactérienne: a) méthode par absorption (méthode d'évaluation dans laquelle la suspension bactérienne à l'essai est ensemencée directement sur des échantillons); b) méthode par transfert (méthode d'évaluation dans laquelle les bactéries soumises à l'essai sont placées sur une boîte de milieu gélosé, puis transférées sur des échantillons); c) méthode par impression (méthode d'évaluation dans laquelle les bactéries soumises à l'essai sont placées sur un filtre, puis imprimées sur des échantillons);
La technique de dénombrement et la méthode de mesure de luminescence ATP (triphosphate d'adénosine) sont également spécifiées pour le dénombrement des bactéries.
