Textiles - Tests for colour fastness - Part A03: Grey scale for assessing staining (ISO 105-A03:1993)
Describes the grey scale for determining staining of adjacent fabrics in colour fastness tests, and its use. A precise colorimetric specification of the scale is given as a permanent record against which newly prepared working standards and standards that may have changed can be compared. The essential scale (5 steps) consists of pairs of non-glossy grey or white colour chips (or swatches of grey or white cloth). In addition, an augmented scale includes four half-steps and, thus, 9 steps.

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 dégorgements provoqués sur les tissus témoins 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.

ISO 105-A03:1993(E) 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 (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 ISO 1050AO3 was prepared by Technical Committee lSO/TC 38, Textiles, Sub-Committee SC 1, Tests for coloured textiles and coloran ts. This fourth edition cancels and replaces the third edition (ISO 105-AO3:1987), of which it constitutes a minor revision. ISO 105 was previously published in thirteen “Parts”, each designated by a Ietter (e.g. “Part A”), with publication dates between 1978 and 1985. Esch patt 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 . 0 ISO 1993 All rights reserved.

INTERNATIONAL STANDARD ISO 105A03:1993(E) Textiles - Tests for colour fastness - Part A03: Grey scale for assessing staining 1 Scope This part of ISO 105 describes termining staining of adjacent ness tests, and its use. A the grey scale for de- fabrics in colour fast- precise colorimetric L specification of the scale is given as a permanent record against which newly prepared working stan- dards and Standards that may have changed tan be compared. 2 Principle 2.1 The essential, or 5-Step, scale consists of five pairs of non-glossy grey or white colour Chips (or swatches of grey or white cloth), which illustrate the perceived colour differentes corresponding to fast- ness ratings 5, 4, 3, 2 and 1. This essential scale may be augmented by the Provision of similar Chips or swatches illustrating the perceived colour differentes corresponding to the half-Step fastness ratings 4-5, 3-4, 2-3 and l-2, such scales being termed 9-step scales. The first member of each pair is white in col- our and the second member of the pair illustrating fastness rating 5 is identical with the first member. The second members of the remaining pairs are in- creasingly darker in colour so that each pair illustrates increasing contrasts or perceived colour differentes which are defined colorimetrically. The full colorimetric specification is given below. 2.2 The Chips or swatches shall be white or neutral grey in colour and shall be measured with a spectrophotometer with the specular component in- cluded. The colorimetric data shall be calculated using Cl E 1964 supplementary Standard colorimetric sys- tem (10” observer data) for illuminant D,,. 2.3 The Y tristimulus value of the first member (white) of each pair shall be not less than 85. 24 that The second member of each pair shall be such the colour differente between it and the adjacent first member is as follows: Fastness CIELAB differ- grade ence 5 (4-5) 4 (
