Textiles - Methods for analysis of woven fabrics construction - Part 2: Determination of number of threads per unit length (ISO 7211-2:2024)

This document specifies three methods for the determination of the number of threads per centimetre in woven fabrics. Any of the three methods can be used, the choice depending on the character of the fabric. However, in case of dispute, method A takes precedence.
—     Method A: Dissection of fabric, suitable for all fabrics. This is the most laborious method but has fewer limitations than the others; in particular, it is the only one that is really suitable for the examination of certain folded structures and other complicated weaves.
—     Method B: Counting glass, suitable for fabrics with more than 50 threads per centimetre.
—     Method C: Traversing thread counter, suitable for all fabrics.
Where the number of threads per centimetre is low, it can be convenient to express the results as the number of threads per decimetre.

Textilien - Verfahren zur Analyse des Aufbaus von Webwaren - Teil 2: Bestimmung der Anzahl der Fäden je Längeneinheit (ISO 7211-2:2024)

Dieses Dokument legt drei Verfahren für die Bestimmung der Anzahl von Fäden je Zentimeter in Webwaren fest. Jedes der drei Verfahren kann verwendet werden, wobei die Wahl von der Art des Flächengebildes abhängt. Allerdings hat im Schiedsfall das Verfahren A Vorrang.
-   Verfahren A: Zerlegung eines Flächengebildes, geeignet für alle Flächengebilde. Das ist das arbeitsaufwendigste Verfahren, es hat jedoch weniger Einschränkungen als die anderen Verfahren; vor allem ist es das einzige, das für die Untersuchung bestimmter Doppelbindungen und anderer komplizierter Webarten wirklich geeignet ist.
-   Verfahren B: Fadenzähler, geeignet für Flächengebilde mit mehr als 50 Fäden je Zentimeter.
-   Verfahren C: Rasterfadenzähler, für alle Flächengebilde geeignet.
Ist die Anzahl der Fäden je Zentimeter klein, kann es zweckmäßig sein, die Ergebnisse als Anzahl der Fäden je Dezimeter anzugeben.

Textiles - Méthodes d'analyse de la construction des tissus - Partie 2: Détermination du nombre de fils par unité de longueur (ISO 7211-2:2024)

Le présent document spécifie trois méthodes de détermination du nombre de fils par centimètre dans les tissus. Chacune de ces trois méthodes peut être utilisée, le choix dépendant des caractéristiques du tissu. Cependant, en cas de litige, la méthode A est recommandée.
—     Méthode A : Par détissage du tissu, applicable à tous les tissus. S'il s'agit de la méthode la plus laborieuse, son utilisation est toutefois moins limitée par rapport aux autres méthodes ; c'est notamment la seule qui convienne réellement pour l'examen de certaines structures plissées et d'autres armures complexes.
—     Méthode B : Par comptage au moyen de la loupe du compte-fils, applicable aux tissus comportant plus de 50 fils par centimètre.
—     Méthode C : Par comptage au moyen d'un compteur de fils à déplacement transversal, applicable à tous les tissus.
Lorsque le nombre de fils par centimètre est faible, il peut être pratique d'exprimer les résultats en nombre de fils par décimètre.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
