|Publication Date:||10 May 1998|
|ICS Code (Binders. Sealing materials):||91.100.50|
1.1 These test methods cover procedures for sampling and testing emulsified bitumens used in relatively thick films as protective coatings for metals and built-up roofs.
1.2 The test methods appear in the following order:
Test Procedures for All Coatings Section Sampling 4 Uniformity 5 Resistance to Freezing 6 Weight per Gallon 7 Residue by Evaporation 8 Volatiles 9 Ash Content 10 Water Content 11 Flash Point 12 Drying Time 13 Resistance to Heat 14 Resistance to Water 15 Flexibility 16 Tests used primarily for coatings used over metals and built-up roofs Brush-Application Behavior 17 Spray-Application Behavior 18 Wet Flow 19 Direct-Flame Test 20 Solubility of Residue in Trichloroethylene 21 Tests used primarily for coatings used over bituminous pavements Wet Film Continuity 22 Resistance to Volatilization 23 Solubility of Residue in Carbon Disulfide 24 Resistance to Kerosine 2 25 Resistance to Impact 26 Resistance to Impact After Accelerated Weathering 27 Precision ∧ Bias 28
1.3 The values stated in inch-pound 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.
