Textile glass - Yarns - Designation (ISO 2078:1993)

This International Standard specifies a System of designating textile glass yarns [including Single,multiple-wound, folded (plied), cabled and textured yarns, Strands, slivers and rovings] based on their Iinear density expressed in the tex System. This International Standard applies the rules of the
Single-to-fold designation given in ISO 1139 to these textile glass products.

Textilglas - Garne - Bezeichnung (ISO 2078:1993)

Diese Europäische Norm legt ein Bezeichnungssystem für Textiliglasgarne (einschliesslich einfacher und gefachter Garne, einstufiger und mehrstufiger Zwirne, texturierter Garne, Spinnfäden, Stapelfaser-Vorgarnen und Rovings), das  auf ihrer Feinheit im Tex-System beruht, fest. In dieser Europäischen Norm werden für diese Textilglaserzeugnisse die in ISO 1139 angegebenen Regeln für die von der Einfachgarnfeinheit ausgehende Bezeichnung angewandt.

Verre textile - Fils - Désignation (ISO 2078:1993)

La présente Norme internationale établit un système de désignation pour les fils de verre textile (fils simples, assemblés, retors et câblés, texturés, fils de base, rubans et stratifils) à l'aide de la masse linéique, exprimée dans le système Tex. La présente Norme internationale applique les règles de la désignation du fil simple au retors exposée dans l'ISO 1139 à ces fils de verre textile.

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 2078 was prepared by Technical Committee
lSO/TC 61, Hastics, Sub-Committee SC 13, Composites and reinforce-
men t fibres.
This fifth edition cancels and replaces the fourth edition (ISO 2078:1985),
of which subclauses 4.1 .l and 4.2.7 have been technically revised and
clause 2 updated.
