3.1 In production of paints, smoothness of the paint film is of paramount importance. Agglomerates or coarse particles larger than 45 μm are difficult to disperse and may prevent obtaining a smooth film. These test methods are a valuable quality control test for grading raw materials.1.1 These test methods cover the determination of the amount of coarse particles in dry pigments.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers coarse aggregates such as crushed stone, crushed hydraulic-cement concrete, crushed blast-furnace slag, crushed gravel, crushed expanded shale, crushed expanded clay, and crushed expanded slate suitable for use in bituminous paving mixtures. The aggregates shall consist of hard, strong, durable pieces, free of coherent coatings. They shall be sampled for testing, and shall conform to physical requirements as to bulk density, composition for both conventional and open graded friction course mixtures, polishing characteristics, soundness, and degradation behavior.1.1 This specification covers crushed stone, crushed hydraulic-cement concrete, crushed blast-furnace slag, crushed gravel, crushed expanded shale, crushed expanded clay, and crushed expanded slate suitable for use in asphalt paving mixtures, as described in Specification D3515 or D4215.NOTE 1: Other slags having demonstrated a satisfactory service record may be used.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Coarse particles in printing inks reduce the efficiency of the dispersion process, requiring not only extra milling passes, but also frequent changes in pump filters. In printing processes, they may cause excessive wear to metal plates, piling or localized retention of ink on blankets and plates, and water balance problems. Coarse particles also reduce color strength and the gloss of printed matter.4.2 This test method is suitable for quality control. The precision may be improved by the use of a specimen size larger than that prescribed.4.3 Test results are sensitive to the type of washout solvent used. Strong solvents are to be avoided because they may dissolve large particles of resin in the ink vehicle.1.1 This test method covers the determination of the weight concentration of coarse particles in printing ink dispersions by sieve retention.1.2 This test method is applicable to printing inks, flushed pigments, and other pigment dispersions that contain particles larger than 45 μm. With proper choice of solvent, it is applicable both to paste and liquid inks.NOTE 1: This test method is similar in principle to Test Methods D185. For particles under 25 μm, see Test Method D1316.1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method is used primarily to determine the grading of materials proposed for use as aggregates or being used as aggregates. The results are used to determine compliance of the particle size distribution with applicable specification requirements and to provide necessary data for control of the production of various aggregate products and mixtures containing aggregates. The data may also be useful in developing relationships concerning porosity and packing.5.2 Accurate determination of material finer than the 75-μm (No. 200) sieve cannot be achieved by use of this test method alone. Use Test Method C117 for determination of material finer than the 75-μm (No. 200) sieve by washing.5.3 Refer to methods of sampling and testing in Specification C637 for heavyweight aggregates.1.1 This test method covers the determination of the particle size distribution of fine and coarse aggregates by sieving.1.2 Some specifications for aggregates which reference this test method contain grading requirements including both coarse and fine fractions. Instructions are included for sieve analysis of such aggregates.1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.NOTE 1: Sieve size is identified by its standard designation in Specification E11. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size. Specification E11 cites the following with respect to SI units versus inch-pound units as standard. “The values stated in SI units shall be considered standard for the dimensions of the sieve cloth openings and the wire diameters used in the sieve cloth. The values stated in inch-pound units shall be considered standard with regard to the sieve frames, pans,” and covers.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
