5.1 Determination of the color of petroleum products is used mainly for manufacturing control purposes and is an important quality characteristic since color is readily observed by the user of the product. In some cases the color may serve as an indication of the degree of...
1.1 This practice provides a means of specifying the colors of objects in terms of the Munsell color order system, a system based on the color-perception attributes hue, lightness, and chroma. The practice is limited to opaque objects, such as painted surfaces viewed in daylight by an...
1.1 This test method covers a procedure for the visual measurement of the color of near clear liquids. It is applicable only to materials in which the color-producing bodies present have light absorption characteristics nearly identical with those of the Platinum-Cobalt (Pt-Co)...
5.1 The original CIE color scales based on tristimulus values X, Y, Z and chromaticity coordinates x, y are not uniform visually. Each subsequent color scale based on CIE values has had weighting factors applied to provide some degree of uniformity so that color differences in...
1.1 This test method covers the measurement of the color of transparent liquids by means of comparison with arbitrarily numbered glass standards. 1.2 Users of this method should have normal color vision. 1.3 The values stated in SI units are to be regarded as standard. No other units...
This specification establishes the critical controls and requirements for the production of reliable, repeatable, reproducible aerospace parts by the Stratasys Fortus 900mc Plus with Type 1, Class 1, Form 1, Grade 0, Natural Color Material for fused filament fabrication system, but is not...
5.1 High quality physical product standards for color or appearance are the keystone of a successful color control program. Standards are often grouped into three major categories: product standards, intermediate production control standards, and instrument standards. This guide deals...
1.1 This test method covers comparing colors of films (or solids) deposited from the emulsified particles in water emulsion floor polishes. It is based upon luminous reflectance measurements made with tristimulus colorimeters such as the Hunter Color Difference Meter.2 1.2 The values stated...
1.1 This test method covers the quantitative determination of the color of clear, yellow/brown, liquid materials using color measuring instruments. The results may be invalid if other materials are used. The test uses the Gardner color scale described in Test Method?D1544. This...
