Pulps - Determination of alkali resistance

This International Standard specifies a method for the determination of the alkali-insoluble fraction of
pulps using sodium hydroxide solution of fixed concentration. The sodium hydroxide concentrations
most frequently used are 18, 10, and 5 % (m/m).
The method is applicable to all kinds of pulp.

Pâtes - Détermination de la résistance aux solutions d'hydroxyde de sodium

Vlaknine - Določanje odpornosti proti alkalijam

Ta mednarodni standard opredeljuje metodo za določanje alkalnega netopnega dela vlaknin z uporabo raztopine natrijevega hidroksida v točno določeni koncentraciji. Najpogosteje uporabljene koncentracije natrijevega hidroksida so 18, 10 in 5 % (m/m). Metoda se uporablja za vse vrste vlaknin.

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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT), see the following URL: Foreword — Supplementary information.
The committee responsible for this document is ISO/TC 6, Paper, board and pulps.
This third edition cancels and replaces the second edition (ISO 699:1982), of which it constitutes a minor

Introduction
The object of both this International Standard and ISO 692, Pulps — Determination of alkali solubility,
is to permit the study of the behaviour of pulps in the presence of alkali solutions, but their fields of
application are different. While this International Standard describes the gravimetric determination of
the alkali insoluble constituents of the pulp and applies to all categories of pulps, ISO 692 describes the
volumetric determination of the alkali soluble constituents of the pulp and is applied preferably to the
control of bleached pulps.
