【国外标准】 Standard Test Methods for Emulsified Bitumens Used as Protective Coatings (Withdrawn 2012)

These tests are useful in evaluating and characterizing coal tar emulsion and other bituminous emulsions to establish uniformity of shipments.1.1 These test methods cover procedures for sampling and testing emulsified bitumens used in relatively thick films as protective coatings for metals, built-up roofs, and bituminous pavements.1.2 The test methods appear in the following order:Test Procedures for All Coatings SectionSampling 4Uniformity 5Resistance to Freezing 6Weight per Gallon 7Residue by Evaporation 8Volatiles 9Ash Content 10Water Content 11Flash Point 12Drying Time 13Resistance to Heat 14Resistance to Water 15Flexibility 16Tests used primarily for coatings used over metals and built-up roofsBrush-Application Behavior 17Spray-Application Behavior 18Wet Flow 19Direct Flame Test 20Solubility of Residue in Trichloroethylene 21Tests used primarily for coatings used over bituminous pavementsWet Film Continuity 22Resistance to Volatilization 23Solubility of Residue in Carbon Disulfide 24Resistance to Kerosine 25Resistance to Impact 26Resistance to Impact After Accelerated Weathering 27Aggregate (Sand) Content in Bituminous Emulsions 28Precision Bias 291.3 The values stated in SI units are to be regarded as standard. The values 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 and health practices and determine the applicability of regulatory limitations prior to use.
