Textile fibres - Determination of linear density - Gravimetric method and vibroscope method (ISO 1973:1995)

Specifies a gravimetric method and a vibroscope method for the determination of the linear density of textile fibres applicable to bundles of fibres and individual fibres. The procedures can be applied only to fibres which can be kept straight and, in case of bundles, parallel, during test preparation. These methods are properly applicable when the fibres are readily free of crimp. They are not applicable to tapered fibres.

Textilien-Fasern - Bestimmung der Feinheit - Gravimetrisches Verfahren und Schwingungsverfahren (ISO 1973:1995)

Diese Internationale Norm beschreibt zwei Prüfverfahren zur Bestimmmung der Faserfeinheit, jeweils anwendbar auf: a) Faserbündel; b) Einzelfasern. Die Verfahren können nur bei solchen angewandt werden, die bei der Probenvorbereitung gerade gehalten und in Bündeln parallel ausgerichtet werden können. Die Verfahren sind nur dann anwendbar, wenn die Fasern leicht entkräuselbar sind. Für sich verjüngende Fasern sind sie nicht anwendbar. Brauchbare Ergebnisse können bei Chemiefasern erzielt werden, bei Naturfasern nur mit geringerer Genauigkeit.

Fibres textiles - Détermination de la masse linéique - Méthode gravimétrique et méthode au vibroscope (ISO 1973:1995)

La présente Norme internationale prescrit une méthode gravimétrique et une méthode au vibroscope pour la détermination de la masse linéique des fibres textiles, qui s'appliquent respectivement a) aux faisceaux de fibres; b) aux fibres individuelles. Des données utiles peuvent être obtenues pour les fibres artificielles, mais elles sont moins fidèles pour les fibres naturelles. Les modes opératoires prescrits dans la présente Norme internationale ne peuvent être appliqués qu'à des fibres qui peuvent être maintenues rectilignes et, dans le cas de faisceaux, parallèles, durant la préparation pour l'essai. Ces méthodes s'appliquent correctement aux fibres dont la frisure peut être facilement éliminée mais pas aux fibres profilées.
NOTE 1 La méthode au vibroscope peut ne pas être applicable aux fibres creuses et plates (en forme de rubans).

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. Esch 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.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 1973 was prepared by Technical Committee
ISO/TC 38, Textiles, Subcommittee SC 6, Fibre testing.
This second edition cancels and replaces the first edition
(ISO 1973:1976), which has been technically revised.
Annexes A and B of this International Standard are for information only.
