This Draft Uganda Standard covers the calculation, from instrumentally measured color coordinates based on daylight illumination, of color tolerances and small color differences between opaque specimens such as painted panels, plastic plaques, or textile swatches. Where it is suspected that the specimens may be metameric, that is, possess different spectral curves though visually alike in color, Practice D4086 should be used to verify instrumental results. The tolerances and differences determined by these procedures are expressed in terms of approximately uniform visual color perception in CIE 1976 CIELAB opponent-color space, CMC tolerance units, CIE94 tolerance units, the DIN99 color difference formula given in DIN 6176, or the new CIEDE2000 color difference units.

Products Covered: Painted panels, plastic plaques, textile swatches.

This Draft Uganda Standard covers the determination of lead contents between 0.01 and 5 %, cadmium contents between 50 and 150 ppm (mg/kg), and cobalt contents between 50 and 2000 ppm (mg/kg) present in the nonvolatile portion of liquid coatings or contained in dried films. There is no reason to believe that higher levels of all three elements could not be determined by this test method, provided that appropriate dilutions and adjustments in specimen size and reagent quantities are made. Only pigmented coatings were used for evaluating this test method, but there is no reason to believe that varnishes and lacquers could not be analyzed successfully, provided that appropriate precautions are taken. This test method is not applicable to the determination of lead in samples containing antimony pigments (low recoveries are obtained). If lead is present in the sample to be analyzed in the form of an organic lead compound at a concentration greater than 0.1 %, small losses of lead may occur, resulting in slightly poorer precision than shown in Section.

This Draft Uganda Standard describes test procedures for determining the degree of bleeding of traffic or pavement marking paints. A specific formulation for a solventborne traffic paint formulation is included as a potential bleeding reference control. The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

This Draft Uganda Standard covers measurement of the degree of dispersion (commonly referred to as “fineness of grind”) of the pigment in a pigment-vehicle system such as liquid coatings and their intermediates. It may also be used to assess the inclusion of particulates by a cleanliness (or texture) rating. The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

Products Covered: Paints and varnishes, incl. enamels and lacquers, based on synthetic polymers or chemically modified natural polymers, dispersed or dissolved in a non-aqueous medium; solutions of products of subheading 3901 to 3913 in volatile organic solvents, containing > 50% solvent by weight (excl. solutions of collodion) (HS code(s): 3208); Paints and varnishes, incl. enamels and lacquers, based on synthetic polymers or chemically modified natural polymers, dispersed or dissolved in an aqueous medium (HS code(s): 3209); Paints and varnishes (ICS code(s): 87.040)

This Draft Uganda Standard covers the measurement of density of paints, inks, varnishes, lacquers, and components thereof, other than pigments, when in fluid form. For higher precision when working with non-pigmented materials (drying oils, varnishes, resins and related materials), Test Method D1963 can be used to determine specific gravity and, thence, density. The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. Exception—The values for density are to be stated in inch-pound units.

Products Covered: Paints and varnishes, incl. enamels and lacquers, based on synthetic polymers or chemically modified natural polymers, dispersed or dissolved in a non-aqueous medium; solutions of products of subheading 3901 to 3913 in volatile organic solvents, containing > 50% solvent by weight (excl. solutions of collodion) (HS code(s): 3208); Paints and varnishes, incl. enamels and lacquers, based on synthetic polymers or chemically modified natural polymers, dispersed or dissolved in an aqueous medium (HS code(s): 3209); Paints and varnishes (ICS code(s): 87.040); Inks.

This Draft Uganda Standard covers a laboratory procedure for determining the no-pick-up time of a traffic paint. The method uses a wheel consisting of a metal cylinder with rubber O-rings. The wheel is rolled down a ramp over a freshly applied traffic paint film repeatedly until there is no transfer of paint to the rubber rings. The elapsed time from paint film application to point of no paint transfer is the no-pick-up time. Key variables to be controlled during testing are film thickness, temperature, humidity, and air flow. The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

This guide describes procedures for the application of brush or roller, or both, applied paint films to sealed wallboard for evaluating application properties. Because both the application and panel evaluation are subjective, this guide should be used only for comparative testing within one laboratory using one operator for each set of applications, as the ratings assigned by different laboratories may not agree. The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

This test method covers the determination of the content of chromium (including chromium oxide) in the range between 0.005 and 1.0 % present in the solids of liquid coatings or in dried films obtained from previously coated substrates. There is no reason to believe that higher levels could not be determined by this test method, provided that appropriate dilutions and adjustments in specimen size and reagent quantities are made. The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
