Pulps - Determination of dry matter content (ISO 638:1978)

Gives the requirements for balanced biaxially oriented polyethylene terephthalate (PET) film for use as electrical insulation.

Zellstoff(brei)e - Bestimmung des Trockengehaltes (ISO 638:1978)

Diese Internationale Norm beschreibt ein Verfahren zur Bestimmung des Trockenmassegehaltes von Zellstoffproben. Dieses Verfahren gilt für feuchte und lufttrockene Zellstoffe, die keine anderen flüchtigen Bestandteile bei einer vorgegebenen Temperatur enthalten als Wasser. Es wird beispielsweise auf Zellstoffproben für chemische und physikalische Prüfungen im Laboratorium angewendet, die eine übereinstimmende Festlegung des Trockenmassegehaltes verlangen.

Pâtes - Determination de la teneur en matières sèches (ISO 638:1978)

Donne les prescriptions relatives aux films de polyéthylène-téréphtalate (PET) équilibrés, à orientation biaxe, utilisés dans l'isolation électrique.

FOREWORD ISO (the International Organization for Standardization) is a worldwide federation of national Standards institutes (ISO member bodies). The work of developing International Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been set up 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. International Standard ISO 638 was developed by Technical Committee ISO/TC 6, Paper, board and pulps, and was circulated to the member bodies in September 1977. lt has been approved by the member bodies of the following countries : Australia Austria Belgium Canada Chile Czechoslovakia Egypt, Arab Rep. of Finland France Germany, F.R. Hungary India Iran I reland Israel I taly Kenya Korea, Rep. of Mexico Netherlands New Zealand Norway Poland Romania Spain Sweden Switzerland Turkey United Kingdom U.S.A. U.S.S. R. No member body expressed disapproval of the document. This International Standard cancels and replaces ISO Recommendation R 638-1967, of which it constitutes a technical revision. @ International Organkation dar Standardkation, 1978 l Printed in Switzerland SIST EN 20638:2000



INTERNATIONAL STANDARD ISO 638-1978 (E) Pulps - Determination of dry matter content 1 SCOPE AND FIELD OF APPLICATION This International Standard specifies a method for the determination of the dry matter content of pulp samples. This method is applicable to moist or air-dry pulp which does not contain any appreciable quantity of matter, other than water, volatile at the temperature specified for the drying. lt is used, for example, with pulp samples taken for Chemical and physical tests in the laboratory, which require concurrent determination of dry. matter content. This method is not applicable to the determination of the dry ma
