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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
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.
ISO 1833-22 was prepared by Technical Committee ISO/TC 38, Textiles.
ISO 1833 consists of the following parts, under the general title Textiles — Quantitative chemical analysis:

 Part 22: Mixtures of viscose or certain types of cupro or modal or lyocell and flax fibres (method using
formic acid and zinc chloride)
 Part 1: General principles of testing

COMMITTEE DRAFT
ISO/DIS 1833-22

Textiles — Quantitative chemical analysis —
Part 22:
Mixtures of viscose or certain types of cupro or modal or lyocell
and flax fibres (method using formic acid and zinc chloride)
1 Scope
This method is applicable, after removal of non-fibrous matter, to binary mixtures of
 viscose or most of the current cupro or modal or lyocell fibres
with
 flax fibres.
If a cupro or modal fibre is found to be present, a preliminary test should be carried out to see whether it is
soluble in the reagent.
The method is not applicable to mixtures in which the flax fibres has suffered extensive chemical degradation,
nor when the viscose, cupro or modal fibre is rendered incompletely soluble by the presence of certain
permanent finishes or reactive dyes that cannot be removed completely.
This part of ISO 1833 calls for use of substances / procedures that may be injurious to the health /
environment if appropriate conditions are not observed. It refers only to technical suitability and does
not absolve the user from legal obligations relating to health and safety / environment at any stage.
