Blue 15 or PB 15.5.1.5 Substituted PigmentsIn the case of substituted pig-ments, the word “Hue” in equal size letters shall follow in thetitle, on the front of the t
40、ube, immediately after the name of thepigment that has been simulated. Directly below the title, theCommon Name from Table 1 of the pigment(s) used shall begiven in letters no less than the next type size smaller than thetitle; or if more that one pigment is used, then 5.1.7 coveringmixed pigments,
41、can be followed. For example:CADMIUM RED MEDIUM HUE(Naphthol Red AS-OL)COBALT BLUE HUE(Mixture)5.1.6 Proprietary names or optional names may be usedprovided the Common Name(s) given in Table 1 appears on thefront of the label directly under the proprietary or optionalname in letters no less than the
42、 next type size smaller than theproprietary or optional name; or if more than one pigment isused, then 5.1.7 covering mixed pigments, can be followed.5.1.7 Mixed PigmentsArtists paints containing more thanone pigment comply with this specification if all coloredpigments included in the mixture are o
43、n the suitable pigmentlist (Table 1) and provided the mixture itself has passed allother test requirements in this specification. The CommonNames for the pigments in the mixture, or the word “Mixture,”must appear under the title in letters no less than the next typesize smaller than the title. For e

45、egory of the mixture somewhere on the label.The lightfastness category shall be that of the least lightfastpigment. This lightfastness category may be changed if themixture is tested for lightfastness in accordance with TestMethods D 4303 and results indicating a different category aresubmitted to A
46、STM Subcommittee D01.57 for evaluation.5.2 Provide on the label the identification of the gum/resinused.5.3 LightfastnessThe label shall contain the word“ Light-fastness” followed by the appropriate rating, I or II, as givenfor each pigment in Table 1.5.3.1 Lightfastness I pigments, when made into p
47、aint speci-mens as described in Section 7 and exposed, tested, and ratedin accordance with Test Methods D 4303, shall have a colordifference (DE*ab) of 4 or less CIELAB units between thespecimens measured before and after exposure.5.3.2 Lightfastness II pigments, when made into paintspecimens as des
48、cribed in Section 7 and exposed, tested, andrated in accordance with Test Methods D 4303, shall have acolor difference (DE*ab) of more than 4.0 but not more than 8.0CIELAB units between the specimens measured before andafter exposure.5.3.3 Pigments were placed in a lightfastness category onthe basis
49、 of either known historical performance in art works orthe ratings from four lightfastness tests conducted as describedin Test Methods D 4303. Results from further tests on these, orother pigments, are solicited by Subcommittee D01.57.5.3.3.1 The lightfastness category of a pigment shall bechanged if results from several further tests conducted inaccordance with Test Methods D 4303 and approved byASTMSubcommittee D01.57, establish a different lightfastness cat-egory than the one given in Table 1.5.3.3.2 Additional pigments shall be placed in Table 1 afterthey have been te
