Textiles - Determination of the abrasion resistance of knitted footwear garments

This standard specifies two test methods for the determination of abrasion resistance of knitted footwear garments, e.g. ankle socks, socks, and heavy tights. The test methods apply to any of these articles, irrespective of size, composition and structure.

Textilien - Bestimmung der Scheuerbeständigkeit von gestrickter Fußbekleidung

Diese Norm legt zwei Prüfverfahren zur Bestimmung der Scheuerbeständigkeit von gestrickter Fußbekleidung fest, wie z. B. von Fesselsocken, Socken, Strümpfen und dicken Strumpfhosen. Die Prüfverfahren sind auf sämtliche genannten Artikel anwendbar, unabhängig von deren Größe, Zusammensetzung und Ausführung.

Textiles - Détermination de la résistance a l'abrasion des articles chaussants tricotés

La présente Norme européenne spécifie deux méthodes d'essai permettant de déterminer la résistance a l'abrasion des articles chaussants tricotés, tels que les socquettes, les chaussettes et les collants épais. Les méthodes d'essai s'appliquent a tous ces articles, quelles que soient leur taille, composition et structure.

EN 13770:2002 (E)4IntroductionThis European Standard is composed of two tests.The first test describes a method for the determination of the abrasion resistance of knitted footweargarments on samples stretched with a modified sample holder, on a Martindale abrasion machine.The second test describes a testing device and a method for the determination of the abrasionresistance of knitted footwear garments in a stretched controlled state.The test method is chosen before starting the test and recorded in the test report, since the results ofthe different methods cannot be compared with each other.SIST EN 13770:2002

The test methods apply to anyof these articles, irrespective of size, composition and structure.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from otherpublications. These normative references are cited at the appropriate places in the text, and thepublications are listed hereafter. For dated references, subsequent amendments to or revisions of anyof these publications apply to this European Standard only when incorporated in it by amendment orrevision. For undated references the latest edition of the publication referred to applies (includingamendments).EN 20139, Textiles

The resistance to abrasion is estimated by thenumber of cycles to either total breakdown or thinning of one component.4.2 Apparatus and agents4.2.1Martindale abrasion machine as specified in EN ISO 12947–1.4.2.2Modified specimen holders for the evaluation of abrasion of knitted footwear garments (inaccordance with annex A), consisting of a guide spindle, holder body, needle ring, holder nut andrubber sphere with flattened surfaces (20 mm being the test area).4.2.3Springloaded tightening block spanner which enables the tightening of the holder body andholder nut whilst ensuring the flat surface of the rubber sphere remains flat and horizontal.4.2.4Abradant and woven felt as specified in EN ISO 12947–1.SIST EN 13770:2002
