Manufacturers are encouraged to put this completeidentification on the container label when label size permits.5.1.3 The common name shall be placed on the front of thelabel and shall

34、be the name of the paint except as described in5.1.5 and 5.1.6. Other identification may be placed elsewhereon the container.5.1.4 The colour index name may be spelled out in full orabbreviated depending on the size of the label. Example:Pigment Blue 15, or Pig.

36、ters no less than the next type size smaller than thetitle; or if more than one pigment is used, then 5.1.7 coveringmixed pigments 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 n

37、ame(s) given in Table 1 appears on thefront of the label directly under the proprietary or optionalname in letters no less than the 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 Pigment

38、sArtists paints containing more thanone pigment comply with this specification if all coloredpigments included in the mixture are on 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

39、 mixture, or the word “Mixture”must appear under the title in letters no less than the next typesize smaller than the title. For example:PERMANENT GREEN LIGHT PERMANENT GREEN LIGHT(Cadmium Yellow Light, (Mixture)Phthalocyanine Blue)If the word “Mixture” is used under the title, the commonnames of th

40、e pigments in the mixture, as given in Table 1 mustbe listed along with their Colour Index Names and thelightfastness category 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 tes

41、ted in accordance with Test Methods D4303 andthe results indicating a different category are submitted toASTM Subcommittee D01.57 for evaluation.5.2 Provide on the Label:5.2.1 Identification of gum/resin used.5.3 LightfastnessThe label shall contain the word “Light-fastness” followed by the appropri

42、ate rating, I, or II, as givenfor each pigment in Table 1.5.3.1 Lightfastness I pigments, when made into paint speci-mens as described in Section 7 and exposed, tested, and ratedin accordance with Test Methods D4303, shall have a colordifference (DE*ab) of 4 or less CIELAB units between thespecimens

44、tween the specimens measured before andafter exposure.5.3.3 Pigments were placed in a lightfastness category onthe basis of either known historical performance in art works orthe ratings from four lightfastness tests conducted as describedin Test Methods D4303. Results from further tests on these, o

45、rother 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 D4303 and approved by ASTMSubcommittee D01.57, establish a different lightfastness cat-egory than the o

46、ne given in Table 1.5.3.3.2 Additional pigments shall be placed in Table 1 afterthey have been tested for lightfastness in accordance with TestMethods D4303 and the test results submitted to ASTMSubcommittee D01.57 for evaluation, provided the resultsdemonstrate that the pigments have the lightfastn

47、ess ratingsrequired for Lightfastness I or Lightfastness II, as just de-scribed.5.3.4 For information and to establish nomenclature, pig-ments in Lightfastness III, IV and V categories are given inTable X1.1 in Appendix X1, but are not to be used in paintconforming to this specification.5.3.4.1 Ligh

48、tfastness III pigments have a color difference ofmore than 8.0 but not more than 16.0 CIELAB units.5.3.4.2 Lightfastness IV pigments have a color difference ofmore than 16.0 but not more than 24.0 CIELAB units.5.3.4.3 Lightfastness V pigments have a color difference ofmore than 24.0 CIELAB units.5.4
