ASTM D1475-13 (2020) pdf free.Standard Test MethodDensity of Liquid Coatings , Inks , and Related Products.
1.1 This test method covers the measurement of density of paints. inks, varnishes, lacquers, and components thereof, other than pigments, when in fluid form.
1.2 For higher precision when working with nonpigmented materials (drying oils, varnishes, resins and related materials). Test Method D1963 can be used to determine specific gravity and, thence, density.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1 .3. 1 Lxcepnon—The values for density are to be stated in inch-pound units.
1 .4 This standard does not purport to address all of the sa/etv concerns, if associated with i/s use. b is the responsibility of the user of this standard to establish appropriate safet hea liii, and en i ironinental practices and determine the applicability of regulatory limitations prior to use. A specific precaution statement is given in 8.1.1.1.
1 .5 This international standard was dei’elopecl in accordance with international/v recognized principles on standard— ization established in the Decision on Principles for the Development of International Standards, Guides and Recoinmendations issuc’d by the World Trade Oi:c’ani:ation lechnical Barriers to Trade (TBT) Comm ittee.
3. 1 Definitions:
3.1.1 densirs n—the mass of’ a unit volume of a material ata specified temperature. In this method, it is expressed as the weight in grams per millilitre, or as the weight in pounds avoirdupois of one U. S. gallon. of the liquid at the specified emperature: in the absence of other temperature specifIcation,
25°C is assumed.
3. 1 .2 specific grai’itv (re1arie density), n—the ratio of the mass of a unit volume of a material at a stated temperature to the mass of the same volume of distilled water at the same temperature.
4. Summary of Test Method
4.1 The accurately known absolute density of distilled water at various temperatures (Table 1) is used to calibrate the volume of a container. The weight of the paint liquid contents of the same container at the standard temperature (25°C) or at an agreed-upon temperature is then determined and density of the contents calculated in terms of grams per millilitre. or pounds per gallon at the specified temperature.ASTM D1475 free download.
