Textiles - Tests for colour fastness - Part B05: Detection and assessment of photochromism (ISO 105-B05:1993)

A specimen of the textile (coloured textiles which change in colour on exposure to light but which virtually return to their original shade when stored in the dark) is exposed to light of high intensity for a time much shorter than that necessary to cause a permanent change. The change in colour of the specimen is assessed immediately after exposure, using the grey scale. The specimen is then stored in the dark and assessed again.

Textilien - Farbechtheitsprüfungen - Teil B05: Erkennung und Bestimmung der Photochromie (ISO 105-B05:1993)

Dieser Teil von ISO 105 beschreibt ein Prüfverfahren zur Erkennung und Bestimmung der bei kurzzeitiger Einwirkung von Licht zeitweilig auftretenden Änderung der Farbe von Textilien aller Art. Diese Färbänderung kehrt beim Lagern im Dunkeln scheinbar wieder zum Originalfarbton zurück.

Textiles - Essais de solidité des teintures - Partie B05: Détection et évaluation de la phototropie (ISO 105-B05:1993)

La présente partie de l'ISO 105 prescrit une méthode pour la détection et l'évaluation de la dégradation de coloration, après une courte exposition à la lumière, de textiles teints qui changent de coloration à l'exposition à la lumière, mais qui reviennent pratiquement à leur teinte initiale lorsqu'ils sont conservés dans l'obscurité.  
NOTE 1 Ce phénomène est habituellement appelé «phototropisme», mais ce terme est bien plus utilisé en science biologique où sa signification est entièrement différente. Comme la formation du mot «phototropisme» correspond à sa signification biologique, le terme «photochromisme» est préférable pour la désignation des dégradations réversibles de coloration produites par la lumière.

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-B05 was prepared by Technical Committee
ISOflC 38, Textiles, Sub-Committee SC 1, Tests for coloured textiles and
coloran ts.
This fourth edition cancels and replaces the third edition
(ISO 105-B05:1988), of which it constitutes a minor revision.
ISO 105 was previously published in thirteen “Parts”, each designated by
“Part A”), with publication dates between 1978 and 1985.
a letter (e.g.
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 .
