(Specification)Standard Specification for Emulsified Refined Coal Tar (Mineral Colloid Type)
Standard Specification for Emulsified Refined Coal Tar (Mineral Colloid Type)
ABSTRACT
This specification covers mineral-colloid-stabilized, concentrated, emulsified, and refined coal tar suitable for use as weather-protective and aliphatic-solvent resistant coatings over bituminous pavements, such as those found at airports, parking areas, and driveways. The emulsion shall be homogeneous and exhibit no separation or coagulation of components that cannot be overcome by moderate stirring. Specimens shall be sampled and shall undergo tests to examine their conformance with physical properties such as uniformity, wet film continuity, resistance to freezing, density, residue by evaporation, water content, resistance to volatilization and residue weight loss, solubility of residue in CS2, ash of residue, drying time, flexibility, and resistance to heat, kerosene, and water.
SCOPE
1.1 This specification covers mineral-colloid-stabilized, concentrated, emulsified, refined coal tar suitable for use as weather-protective and aliphatic-solvent resistant coatings over bituminous pavements, such as those found at airports, parking areas, and driveways. The specification for this material was previously covered by Federal Specification RP355.
Note 1: Dilute the concentrated emulsion after testing and prior to application to meet the application specification requirements. Application shall be made in accordance with Practice D3423/D3423M.
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 following precautionary caveat pertains only to the test methods portion, Section 6, of this specification: 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.
