Pulps - Determination of acetone-soluble matter (ISO 14453:2014)
EN ISO 14453 describes the determination of acetone-soluble matter in pulp. It is applicable to all types of pulp. The lower limit of the determination is about 0,05 %. This limit can be lowered by increasing the amount of sample analysed.
Faserstoff- Bestimmung acetonlöslicher Bestandteile (ISO 14453:2014)
Diese Internationale Norm legt ein Verfahren zur Bestimmung von acetonlöslichen Bestandteilen in Zellstoff fest.
Sie ist auf alle Sorten von Zellstoffen anwendbar. Die untere Bestimmungsgrenze liegt bei etwa 0,05 %. Dieser Grenzwert kann durch Erhöhen der Menge der zu analysierenden Durchschnittsprobe verringert werden.
Pâtes - Détermination des matières solubles dans l'acétone (ISO 14453:2014)
L'ISO 14453:2014 décrit une méthode de détermination des matières solubles dans l'acétone contenues dans la pâte.
Elle est applicable à tous les types de pâte. La limite inférieure de détermination est d'environ 0,05 %. Il est possible de diminuer cette limite en augmentant le volume de l'échantillon qui est analysé.
Vlaknine - Določevanje v acetonu topne snovi (ISO 14453:2014)

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. www.iso.org/directives

This second edition cancels and replaces the first edition (ISO 14453:1997), which has been technically
revised to include the use of automated extraction, and to add a new precision statement that complies
with the requirements of ISO/TR 24498.

Introduction
The amount of acetone-soluble matter in pulp provides a measure of the content of wood extractives,
often called resin. The acetone-soluble matter includes fatty acids, resin acids, fatty alcohols, sterols,
diglycerides and triglycerides, steryl esters and waxes.
In addition, acetone extracts of mechanical pulps may also contain phenolic compounds such as lignans.
In the case of incompletely washed chemical pulps, the acetone extracts will also include dissolved kraft
lignin.
Metal soaps of fatty and resin acids, such as those present in unwashed or deinked pulp, are not extracted
under the conditions specified in this International Standard.

INTERNATIONAL STANDARD ISO 14453:2014(E)
Pulps — Determination of acetone-soluble matter
1 Scope
This International Standard describes the determination of acetone-soluble matter in pulp.
It is applicable to all types of pulp. The lower limit of the determination is about 0,05 %. This limit can
be lowered by increasing the amount of sample analysed.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 7213, Pulps — Sampling for testing
ISO 638, Paper, board and pulps — Determination of dry matter content — Oven-drying method
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
acetone-soluble matter
amount of material that can be extracted with acetone from a sample of pulp by the method specified in
this International Standard
4 Principle
1)
®
A pulp sample is extracted with acetone in a Soxhlet apparatus (Option A) or in a Soxtec apparatus or
similar extraction equipment (Option B).
®
NOTE Extraction with a Soxtec apparatus is carried out with boiling solvent instead of condensed solvent
®
as is the case with the Soxhlet extraction. The main advantages of the Soxtec system are much shorter extraction
[1] [2]
times and recovery of the main portion of the solvent . Other extraction methods, such as Accelerated Solvent
[2]
Extraction (ASE), can produce different results and are not within the scope of this Internati
