1、for Art Paints and and Craft Inks Materials 1 ANSI Z356.5 1998- ANSI American National Standards Institute 1 11 West 42nd Street New York, NY 10036 American National Approval of an American National Standard requiresverification by ANSI that the requirements for due process, consensus, and other cri
2、teria for approval have been met by the standards developer. Standard Consensus is established when, in the judgement of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple major
3、ity, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has app
4、roved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standa

The American National Standard for Art and Craft Materials - Paints and Inks, ANSI 2356.5 - 1998, was initiated by the Art and Creative Materials Institute, Inc. as a revision to ANSI 2
11、356.5 - 1985. ANSI 2356.5 - 1985 was initiated to replace portions of NBS Voluntary Product Standard PS 65-75 and ANSI 2297.1 - 1975. Since the National Bureau of Standards has withdrawn its Voluntary Product Standards, ANSI Canvass Method procedures were followed. This standard was revised to provi
12、de for the inclusion of liquid watercolor paints and dry pan watercolor paints. The initial draft, prepared by The Art and Craft Materials Institute, Inc. and now called The Art and Creative Materials Institute, Inc., was reviewed and revised by the Institutes Technical and Certification Committees.
13、 The Technical Committee is comprised of the technical directors of member companies and the Certification Committee of representatives of subscribers to the Institutes Certified Products Bureau and four representatives each of the National Art Education Association, the Association of School Busine
14、ss Officials, and Artists Equity Association. The text was also reviewed by the Institutes consultant in toxicology. Suggestions for improving the draft were incorporated in the standard and submitted for review under the ANSI Canvass Method. Suggestions for improvement of this standard will be welc
15、ome. They should be sent to The Art and Creative Materials Institute, 100 Boylston Street, Suite 1050, Boston, MA 021 16. The following organizations and others recognized as having a potential interest in the development of a standard for paints and inks were contacted prior to the approval of this
16、 standard. Inclusion on this list does not necessarily imply that the organization concurred with the submittal of the proposed standard to ANSI. Arts, Crafts, (2) Specific chemical form, bioavailability, levels, and amount of each potentially toxic ingredient found in the formulation; (3) Physical
17、form and reasonably foresee- able uses and misuses of the art material; (4) Potential for known synergism and an- tagonism of the various ingredients in the formulation; (5) Potential acute and chronic toxiceffects of any known decomposition products from any reasonablyforeseeable use of the art mat
18、erial including reasonably foreseeable use by chil- dren; (6) Potential for any ingredient to cause aller- gic sensitization at its use level, or, if the ingredient is a common sensitizer, its poten- tial to cause an allergic reaction in an already- sensitized individual. (7) Opinions of various reg
19、ulatory agencies and scientific bodies including but not limited to those of the International Agency for Re- search on Cancer and the National Cancer Institute on the potential for chronic adverse health effects of the various ingredients of the formulation. 3.5 Coarse Particle Content.

The inspection and test proce- dures contained in this section are to be used to determine the conformance of products to the requirements of this standard. Each pro- ducer or distributor who represents his prod-
38、ucts as conforming to this standard may use statistically based sampling plans that are appropriate for each particular manufacturing process but shall keep such essential records as are necessary to document with a high degree of assurance the claim that all of the requirements of this standard hav
39、e been met. Additional sampling and testing of the product, as may be agreed upon between purchaser and seller, is not precluded by this section. 4.2 Preservative. The effectiveness of paint and ink preservatives should be tested as follows. Cover several pieces of bread with a sugar and water solut
40、ion containing five per- cent sugar by weight and allow time to stand exposed for 24 hours. Cover them and allow them to stand at room temperature until a substantial area is moldy. (This will require approximately a week to ten days.) Select two moldy pieces, each approximately 1/4 inch in diameter
41、 from the bread and push them lightly into the surface of the material being tested. Make sure there is good wet contact but do not submerge the mold in the product. Cover the test sample so as to avoid excessive evapora- tion and to provide subdued lighting. Allowthie sample to remain in this state
42、 for two weeks at room temperature and then inspect the sample for decomposition, scum and mold growth. 4.3 Coarse Particle Content. The coarse particle content shall be determined in accor- dance with Section 8, “Procedure for Water- Soluble Pigments, Pastes in Oil, Pastes, in Japan, and Mixed Pain
43、ts,“ in ASTM Dl 85-84, the exception being that watershall be substi- tuted for kerosene as a flushing vehicle or solvent. 4.4 Performance. Using paintouts prepared as specified in (1) through (13), place the specimens in a controlled atmosphere of 73 OF +- 3F and relative humidity of 50% k 5%. Afte
44、r 14 days, inspect the specimens for com- pliance with 3.6. All paintouts shall be completely dry before testing. Where drawing paper is specified, 4 ANSI 2356.5 - 1998 white textured, 80-pound drawing paper shall be used. Unless otherwise indicated, an area of at least 20 square inches shall be cov
45、ered using a soft bristled brush. Paintouts shall be prepared as follows: (1) Liquid finger paint. Spread the finger paint by hand on wet finger paint paper. (2) Powder finger paint. After mixing the powder finger paint with water according to manufacturers directions on the container, spread the fi
46、nger paint by hand on wet finger paint paper. (3) Liquid tempera. Mix liquid tempera thor- oughly to ensure uniformity. Paint out on drawing paper. (4) Acrylic paint, permanent. Mix paint thor- oughly to ensure uniformity. Paint out on prepared canvas or drawing paper as indi- cated in 3.6.3. (5) Ac
47、rylic paint, washable. Use drawing paper. Apply paint to half the area with a bristle brush and to the other half with a palette knife, covering some of the area to a depth of 1/32 of an inch. (6) Powder tempera. For test purposes, mix one part tempera to one part water (by weight) and stir thorough
48、ly to ensure unifor- mity. Paint out on drawing paper. (7) Cake tempera. Using a wet brush, brush over the cake tempera until a sufficient amount of color is picked up. Spread paint on drawing paper. (8) Semi-moist watercolors. Using a wet brush, brush over the paint until a sufficient amount of pai
49、nt is picked up. Spread paint on drawing paper. (9) Dry pan watercolors. Using a wet brush, brush overthe paint until a sufficient amount of paint is picked up. Spread paint on draw- ing paper. (1 0) Liquid watercolors. Mix liquid watercol- ors in jars thoroughly to ensure uniformity. Paint out on drawing paper. (1 1) Watercolor crayons. Color an area 1 inch by 2 inches on white drawing paper using uniform pressure. Completely brush the area covered by the crayon markings with a clean, water-soaked brush. (12) Watercolor markers. Apply ink, using the widest contact area of the nib.
