Textiles - Essais de solidité des teintures - Partie A02: Echelle de gris pour l'évaluation des dégradations (ISO 105-A02:1993)

La présente partie de l'ISO 105 donne la description et le mode d'emploi de l'échelle de gris prescrite pour l'évaluation des dégradations de la coloration des textiles provoquées par les essais de solidité. Une spécification colorimétrique précise de cette échelle est donnée comme référence; elle permet de vérifier des échelles de gris nouvellement établies, ou qui pourraient se trouver modifiées après un certain usage.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
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. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) 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 IS0 105.A02 was prepared by Technical Committee
ISO/TC 38, Textiles, Sub-Committee SC 1, Tests for co/owed textiles and
colorants.
This fourth edition cancels and replaces the third edition
(IS0 105-A02:1987), of which it constitutes a minor revision.
IS0 105 was previously published in thirteen “parts”, each designated by
a letter (e.g.
“Part A”), with publication dates between 1978 and 1985.
Each part contained a series of “sections”, each designated by the re-
spective part letter and by a two-digit serial number (e.g. “Section A01 “).
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 IS0 105-AOI .
