16、edin this specification.3.2 Definitions of Terms Specific to This Standard:3.2.1 alkali refined oil, ntriglyceride oil of vegetableorigin that has been treated with alkali to reduce the free acidityby formation of water-soluble salts, subsequently removed bywashing.3.2.1.1 DiscussionAn appreciable d
17、egree of free aciditymay cause a greater development of yellowing in a dried filmof oil. Most artists oil paints are ground in alkali refined oil.3.2.2 alkyd paint, npaint containing a resin produced bycombining a polybasic acid, a polyhydric alcohol, and the fattyacid of a drying vegetable oil. For
18、 this specification, the resinproduced must be soluble in mineral spirits or turpentine.3.2.3 drier (siccative), na substance, usually an organo-metallic compound, that accelerates the rate of drying of an oilpaint or oil medium.3.2.4 oil paint, npaint containing an alkali refined triglyc-eride dryi
19、ng oil of vegetable origin.3.2.5 resin-oil paint, npaint containing 90 weight %minimum of vehicle solids, vegetable drying oil, and 10 weight% maximum of vehicle solids replaced by gum or resin.4. Significance and Use4.1 This specification establishes quality requirements andprovides a basis for com
20、mon understanding among producers,distributors, and users.4.2 It is not intended that all paints meeting the require-ments be identical nor of uniform excellence in all respects.Variations in manufacture, not covered by this specification,may cause some artists to prefer one brand over another, eith
21、erof which may be acceptable under this specification.5. Labeling Requirements5.1 Pigment(s) Identification:5.1.1 Every label shall include for each pigment containedin the paint (1) the information underlined in Table 1 (whichincludes the Common Name, Colour Index Name, and anyadditional terms nece
22、ssary to identify the form of the pigment)and (2) the appropriate Lightfastness Category.5.1.2 The complete pigment identification given in Table 1,which also includes the Colour Index Number and a simplechemical description, shall be given in an appropriate producerpublication. Manufacturers are en
23、couraged 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 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 C
24、olour Index name may be spelled out in full orabbreviated depending on the size of the label. Example:Pigment Blue 15, or Pig. Blue 15 or PB 15.5.1.5 Substituted PigmentIn the case of substituted pig-ments, the word “Hue” in equal size letters shall follow in thetitle, on the front of the tube, imme
25、diately 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, can be fo
26、llowed. For example:CADMIUM RED MEDIUM HUE COBALT BLUE HUE(Naphthol Red AS-OL) (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 next t
27、ype 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 on the s
28、uitable 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 example:
29、PERMANENT GREEN LIGHT PERMANENT GREEN LIGHT(Cadmium Yellow Light, (Mixture)Phthalocyanine Blue)If the word “Mixture” is used under the title, the CommonNames of the pigments in the mixture, as given in Table 1,must be listed along with their Colour Index Names and theLightfastness Category of the mi
30、xture 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 D4303 and results indicating a different category aresubmitted to ASTM Subcommittee
31、 D01.57 for evaluation.5.2 Provide on the label:5.2.1 Artists Oil PaintsVegetable origin of the oil andmethod of refinement.NOTE 1The type of oil can be identified in accordance with TestMethod D2245.5.2.2 Artists Alkyd PaintsType of fatty acid used. If freevegetable oil is used in combination with
32、an alkyd resin,declare this also on the label. State if compatible with artistsoil paints.NOTE 2The type of alkyd can be identified in accordance withPractices D2689.5.2.3 Artists Resin-Oil PaintsVegetable origin andmethod of refinement of the oil and type of resin or gum. If thecolors in a resin-oi
33、l paint line contain more than one, ordifferent, gums or resins, the identification on the individuallabels may uniformly include all of the gums or resins used inthe paint line. Example: “Damar or Mastic Gum.” State ifcompatible with artists oil paints.NOTE 3The type of oil can be identified in acc
34、ordance with TestMethod D2245.5.3 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 paint speci-mens as described in Section 8 and exposed, tested, and ratedin
35、 accordance with Test Methods D4303, shall have a colorD4302 05 (2010)2difference (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 described in Section 8 and exposed, tested, andrated in accord
36、ance with Test Methods D4303, 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 of either known historical performance in art works orthe r
37、atings from four lightfastness tests conducted as describedin Test Methods D4303. 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 w

Quality Assurance for Artists Oil Paints and ArtistsResin-Oil Paints6.1 Conditions Not Covered in This Specification that AffectArtists Oil and
43、Resin-Oil Paints:6.1.1 SubstrateFactors such as the texture, gloss, effectivepH, porosity, chemical composition, and condition of thesubstrate will affect gloss, gloss uniformity, drying time,adhesion, and the flexibility of the dried film.6.1.2 Environmental ConditionsFactors such as tempera-ture,
44、humidity, air flow, and light conditions affect applicationproperties, film formation, drying time, and adhesion.6.1.3 StorageWith aging and elevated temperatures, theremay be a change in consistency and a separation of oil from thepaste paint.6.2 VehiclesOnly vegetable drying oils shall be used ina
45、rtists oil paints. Resin-oil paints shall contain 90 weight %minimum of vehicle solids, vegetable drying oil (see Note 1),and 10 weight % maximum of vehicle solids replaced by gumor resin.6.3 PigmentsPigments to be used in oil paints shall belimited to those listed in the column labeled “Oil” andpig
46、ments to be used in resin-oil paints shall be limited to thoselisted in the column labeled “Resin-Oil” in Table 1. Theirlightfastness rating shall be the numeral given in the same row.Those pigments listed as “not tested” shall not be used.6.4 DriersDriers may be used in minimal amounts inpaints tha
47、t contain a pigment which has a retarding effect onthe drying of oil. This is allowed so these paints can conformto the drying requirements of this specification.6.5 InertsMinimal amounts of inert pigments may beused to produce desirable working qualities and consistency, toprevent separation, to de
48、velop chromatic properties, or toensure the durability of the paint film.6.6 Preparation of SampleEmpty the contents of a previ-ously unopened container onto a glass slab and mix thoroughlywith a spatula to a homogeneous sample.6.7 NonvolatileThe nonvolatile content shall not be lessthan 97 weight %
