This specification covers epoxy-coated steel wires, in coils, for general use. The protective epoxy coatings covered here are available in three classes, namely: Class A, which are intended for use in moderate corrosion protection; Class B, which are intended for more severe protection; and Class C, which are intended for severe corrosion and abrasion protection. Prior to cleaning and coating, the steel wires shall be free of surface contaminants such as oil, grease, or paint. Wire surfaces shall be cleaned by abrasive cleaning or chemical cleaning to ensure proper adherence of the epoxy. Coatings shall then be applied as soon as possible after cleaning, before possible oxidation, and shall be properly cured. Wrap, bend and tensile tests shall be performed in order to evaluate coating properties, including thickness, continuity, adherence, size tolerance, and tensile strength.1.1 This specification covers steel wire in the size range of 0.120 to 0.500 in. (3.05 to 12.7 mm) with three classes of protective epoxy coating, in coils, for general use. Class A coating is intended for use for moderate corrosion protection, Class B coating for more severe protection, and Class C for severe corrosion and abrasion protection.NOTE 1: The coating applicator is identified throughout this specification as the manufacturer.1.2 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only.1.3 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 Test Method D2047 establishes a compliance criterion relating static coefficient of friction measurements of flooring surfaces with human locomotion safety. The compliance criterion is based on extensive experiential data from residential, commercial, industrial and institutional walkway surfaces since 1942.4.2 Polishes and other floor maintenance coatings having a static coefficient of friction of not less than 0.5, as measured by this test method, have been recognized as providing nonhazardous walkways.NOTE 1: The value of 0.5 meets the requirements for compliance with Rule 5 on “The use of terms slip retardant, slip resistant, or terms of similar import,” of the Proposed Trade Practice Rules for the Floor Wax and Floor Polish Industry as issued by the Federal Trade Commission on March 17, 1953.4.3 The 0.5 static coefficient of friction compliance criterion of this test method is only appropriate for polish-coated surfaces tested in accordance with this machine and test method. The use of this compliance criterion with other test methods, other test instruments, and other surfaces is improper, because they are not a part of the body of experiential data upon which the conformance criterion is based.NOTE 2: The conformance criteria of this test method may be valid for other surfaces and surface coatings tested by this test method, but this has not been substantiated by correlation with experiential data.1.1 This laboratory test method covers the use of the James Machine for the measurement of the static coefficient of friction of polish-coated flooring surfaces with respect to human locomotion safety. Further, this test method also establishes a compliance criterion to meet the requirement for a nonhazardous polished walkway surface. The test method is not intended for use on “wet” surfaces or on surfaces wherein the texture, projections, profile or clearance between the sculptured pattern of the surface does not permit adequate contact between the machine foot and the test surface.1.2 This test method is the only method appropriate for testing polishes for specification compliance with the floor polish static coefficient of friction criterion.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.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.

3.1 This test method is useful in calculating percent air voids as given in Test Method D3203/D3203M. Since specific gravity has no units, it must be converted to density when this type of measurement is required. This conversion is made by multiplying the specific gravity at a given temperature by the density of water at the same temperature.NOTE 2: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.1.1 This test method covers the determination of bulk specific gravity of specimens of Parafilm-coated, compacted asphalt mixtures.1.2 This method should be used with samples that contain open or interconnecting voids or absorb more than 2.0 % of water by volume, or both.NOTE 1: A method for calculating the percent water absorbed by the specimen on a volume basis is described in Test Method D2726/D2726M.1.3 The bulk specific gravity of the compacted asphalt mixtures may be used in calculating the unit weight of the mixture.1.4 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.1.5 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.1.6 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.1.7 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.
