(Main)Textiles - Determination of antibacterial activity of textile products (ISO 20743:2013)
Textiles - Determination of antibacterial activity of textile products (ISO 20743:2013)
ISO 20743:2013 specifies quantitative test methods to determine the antibacterial activity of all antibacterial textile products including nonwovens.
ISO 20743:2013 is applicable to all textile products, including cloth, wadding, thread and material for clothing, bedclothes, 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 and also on the surface properties of the textile properties, the user can select the most suitable of the following three inoculation methods on determination of antibacterial activity:
a) absorption method (an evaluation method in which the test bacterial suspension is inoculated directly onto specimens);
b) transfer method (an evaluation method in which test bacteria are placed on an agar plate and transferred onto specimens);
c) printing method (an evaluation method in which test bacteria are placed on a filter and printed onto specimens).
The colony plate count method and the ATP (ATP = Adenosine Tri-phosphate) luminescence method are also specified for measuring the enumeration of bacteria.
Textilien - Bestimmung der antibakteriellen Wirksamkeit von textilen Produkten (ISO 20743:2013)
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 textiles (ISO 20743:2013)
L'ISO 20743:2013 spécifie des méthodes d'essai quantitatives permettant de déterminer l'activité antibactérienne de tous les produits textiles antibactériens, y compris les nontissés.
L'ISO 20743:2013 s'applique à tous les produits textiles, y compris l'étoffe, le rembourrage, le fil et les matériaux utilisés pour les vêtements, la literie, l'ameublement et divers articles, 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, et également des propriétés de surface du textile, l'utilisateur peut choisir la plus adaptée des trois méthodes d'ensemencement suivantes pour la détermination de l'activité antibactérienne:
a) méthode par absorption (méthode d'évaluation dans laquelle la suspension bactérienne d'essai est ensemencée directement sur des éprouvettes);
b) méthode par transfert (méthode d'évaluation dans laquelle les bactéries d'essai sont placées sur une boîte de milieu gélosé, puis transférées sur des éprouvettes);
c) méthode par impression (méthode d'évaluation dans laquelle les bactéries d'essai sont placées sur un filtre, puis imprimées sur des éprouvettes).
La technique de dénombrement et la méthode de mesure par luminescence de l'ATP (adénosine triphosphate) sont également spécifiées pour le dénombrement des bactéries.
Tekstilije - Ugotavljanje protibakterijske aktivnosti na tekstilnih izdelkih (ISO 20743:2013)
Ta mednarodni standard določa kvantitativne preskusne metode za ugotavljanje protibakterijske aktivnosti na vseh tekstilnih izdelkih, vključno z vlaknovinami. Ta mednarodni standard se uporablja za vse tekstilne izdelke, vključno z blagom, vato, nitmi in materialom za oblačila, izdelki za opremljanje domov in drugo, ne glede na vrsto uporabljene protibakterijske učinkovine (organskega, neorganskega, naravnega ali kemičnega izvora) ali način uporabe (vgrajeno, naknadna obdelava ali cepljenje). Na podlagi nameravane uporabe in okolja, v katerem se bo tekstilni izdelek uporabljal, lahko uporabnik izbere najbolj primerno izmed naslednjih treh metod za določanje protibakterijske aktivnosti: a) metodo absorpcije (metoda ocenjevanja, pri kateri je testna suspenzija bakterij vcepljena neposredno na vzorce); b) metoda prenosa (metoda ocenjevanja, pri kateri se testne bakterije razlijejo na ploščo gojišča in prenesejo na vzorce); c) metoda tiskanja (metoda ocenjevanja, pri kateri se testne bakterije razlijejo na filter in natisnejo na vzorce). Metoda za štetje kolonij in luminescenčna metoda z ATP-jem (ATP = adenozin trifosfat) sta tudi določeni za merjenje števila bakterij.
