11、 Copy, (c) BSI ISO 105-A08:2001(E) iii 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 bod
12、y 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 Electrote
13、chnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Pub
14、lication 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 part of ISO 105 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such
15、 patent rights. International Standard ISO 105-A08 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and colorants. ISO 105 was previously published in thirteen “parts”, each designated by a letter (e.g. “Part A”), with publication dates between
16、1978 and 1985. Each part contained a series of “sections”, each designated by the respective part letter and by a two-digit serial number (e.g. “Section A01”). These sections are now being republished as separate documents, themselves designated “parts” but retaining their earlier alphanumeric desig
17、nations. A complete list of these parts is given in ISO 105-A01.

18、RISO -501A:80(1002)E 1 Textiles Tests for colour fastness Part A08: Vocabulary used in colour measurement 1Scope This part of ISO 105 specifies the terms and definitions on colour measurements that are used throughout ISO 105. These definitions are intended to be used only within the context and sco
19、pe of ISO 105. 2Terms and definitions 2.1 chroma attribute of colour used to indicate the degree of departure of the colour from a grey of the same lightness NOTEC*abis the metric chroma defined in the CIELAB equation. 2.2 CIE 1976,L*,a*,b* colour space CIELAB colour space transform of CIE tristimul
20、us values into an approximately uniform, three dimensional, opponent colour space NOTEIts opponent variables are lightness-darkness (L*), redness-greenness (a*) and yellowness-blueness (b*). The last two may be further transformed into those of chroma (C*ab) and hue (hab). 2.3 CIE 1976,L*,a*,b* colo
21、ur difference CIELAB colour difference ?E*ab Euclidean distance between the points representing a test specimen and its reference specimen in CIELAB colour space 2.4 CIE chromaticity coordinates ratios of each of the members of a set of CIE tristimulus values to their sum NOTEThe corresponding symbo
22、ls are x10, y10and z10for X10, Y10and Z10, and x, y and z for X, Y and Z. Since x10+ y10+ z10= 1 and x + y + z = 1, x10and y10or x and y suffice to define chromaticity. 2.5 CIE standard observer data relative amounts of three defined colour stimuli required, when mixed additively, by the average obs

25、65 (average daylight including the ultraviolet region). The CIE also defines the F series (F1 to F12) of recommended illuminants representative of various fluorescent discharge lamps. 2.7 CIE tristimulus values amounts of three non-real reference colours required to give a colour match to the colour
26、 stimulus considered and defined by the CIE for the CIE 1931 (2) and 1964 supplementary (10) standard colorimetric observers and for particular conditions of illumination NOTECorresponding symbols are X, Y and Z for the 2 and X10, Y10and Z10for the 10 observers. 2.8 colour change change in colour of
