Textiles - Tests for colour fastness - Part Z07: Determination of application solubility and solution stability of water-soluble dyes (ISO 105-Z07:1995)

This standard specifies a method for determining the solution stability of water soluble dyes.

Textilien - Farbechtheitsprüfungen - Teil Z07: Bestimmung der Löslichkeit und der Lösungsbeständigkeit von wasserlöslichen Farbstoffen (ISO 105-Z07:1995)

Dieser Teil von ISO 105 legt ein Verfahren fest zur Bestimmung der Löslichkeit von wasserlöslichen Farbstoffen im Bereich von 40°C bis 90°C sowie ihrer Lösungsbeständigkeit. Das Verfahren ist nicht für die Messung der absoluten Löslichkeit vorgesehen.

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. Esch 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
(1 EC) on all matters of electrotechnical standardization.
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.
International Standard ISO 105-207 was prepared by Technical Committee
lSO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and
coloran ts.
ISO 105 was previously published in thirteen “Parts ”, each designated by
a letter (e.g. “Part A ”), with publication dates between 1978 and 1985.
Esch part contained a series of “sections ”, each designated by the re-
spective part letter and by a two-digit serial number (e.g. “Section AO1 “).
These sections are now being republished as separate documents, them-
selves designated “Parts” but retaining their earlier alphanumeric desig-
nations. A complete list of these Parts is given in ISO 105-AOI.
Annex A of this part of ISO 105 is for information only.
