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

Specifies a system of designating textile glass yarns based on their linear density expressed in the Tex System. The designation of a yarn consists of following elements: Type of glass used; type of yarn (continous or staple fiber); nominal diameter of fiber; linear density, direction, amount of twist and number of components. The definitions and rules of the singel-to-fold designation given in ISO 1139 are applied to these textile glass products.

Textilglas - Garne - Bezeichnung (ISO 2078:1993)

ISO 2078:1993(E)
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.
