Textiles - Quantitative chemical analysis - Part 2: Ternary fibre mixtures (ISO 1833-2:2020)
This document specifies methods of quantitative analysis of various ternary mixtures of fibres.
The field of application of each method for analysing mixtures, specified in the parts of ISO 1833, indicates the fibres to which the method is applicable.
This document is applicable to mixtures of fibres with more than three components provided that the combination of test methods leads back to simple cases of fibre mixtures. Table B.1 illustrates the typical ternary mixtures and their applied corresponding parts of the ISO 1833 series.
Textilien - Quantitative chemische Analysen - Teil 2: Ternäre Fasermischungen (ISO 1833-2:2020)
Dieses Dokument legt Verfahren der quantitativen Analyse verschiedener ternärer Fasermischungen fest.
Der in den verschiedenen Teilen von ISO 1833 festgelegte Anwendungsbereich jedes Verfahrens zur Analyse von Mischungen gibt an, für welche Fasern das Verfahren anzuwenden ist.
Dieses Dokument ist anzuwenden für Fasermischungen mit mehr als drei Bestandteilen, sofern die Kombination der Prüfverfahren auf einfache Fälle von Fasermischungen zurückgeht. Tabelle B.1 veranschaulicht die typischen ternären Mischungen und deren zugehörige anwendbare Teile der Normenreihe ISO 1833.
Textiles - Analyse chimique quantitative - Partie 2: Mélanges ternaires de fibres (ISO 1833-2:2020)
Le présent document spécifie des méthodes d'analyse quantitative de divers mélanges ternaires de fibres.
Le domaine d'application de chaque méthode d'analyse de mélanges, spécifié dans les différentes parties de l'ISO 1833, indique les fibres auxquelles la méthode est applicable.
Le présent document s'applique aux mélanges de fibres de plus de trois composants sous réserve que l'association des méthodes d'essai renvoie à des cas simples de mélanges de fibres. Le Tableau B.1 donne les mélanges ternaires types ainsi que les parties correspondantes applicables de la série ISO 1833.

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 of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso .org/

This document was prepared by Technical Committee ISO/TC 38, Textiles, in collaboration with the
European Committee for Standardization (CEN) Technical Committee CEN/TC 248, Textiles and textile
products, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna
Agreement).
This second edition cancels and replaces the first edition (ISO 1833-2:2006), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— the Introduction has been deleted and relevant information have been moved to Clause 4;
— Clause 2 has been updated;
— the mandatory Clause 3 has been added;
— in Clause 4 (former Clause 3), the explanation of the 4 variants has been added;
— in 9.3, additional instruction in case of pre-treatment by extraction with light petroleum and water
has been introduced;
