【国外标准】 Standard Specification for Emulsified Refined Coal-Tar (Ready to Use, Commercial Grade)

This specification covers mineral-colloid-stabilized, emulsified refined coal tar suitable for use as a weather-protective and petroleum (aliphatic) solvent resistant coating. This product is typically applied to commercial lots and other low speed bituminous concrete pavements suitable for protection. The material shall be classified as: Type I and Type II. The refined coal tar emulsion seal coat shall consist of a mixture of refined coal tar emulsion, water, and aggregate and be proportioned within the ranges specified. Mixture and aggregate verification tests shall be performed to conform with the specified requirements.1.1 This specification covers mineral-colloid-stabilized, emulsified refined coal tar suitable for use as a weather-protective and petroleum (aliphatic) solvent resistant coating. This product is typically applied to commercial lots and other low-speed bituminous concrete pavements suitable for protection.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 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.
