  • COEFFICIENT OF KINETIC FRICTION FOR WAX COATINGS: ASTM D2534 COEFFICIENT OF KINETIC FRICTION FOR WAX COATINGS: ASTM D2534EXPLANATIONThe coefficient of friction is related to the slip properties of many commercial articles which have been coated with petroleum wax (e.g., butter cartons and wax impregnated or hot melt coated corrugated board). This test method covers ...
  • FRICTION AND WEAR PROPERTIES OF LUBRICATING GREASE: ASTM D5707 FRICTION AND WEAR PROPERTIES OF LUBRICATING GREASE: ASTM D5707EXPLANATIONThis test method is used for determining wear properties and coefficient of friction of lubricating greases at selected temperatures and loads specified for use in applications where high-speed vibrational or start-stop motions ...
  • COEFFICIENT OF FRICTION OF LUBRICANTS: ASTM D5183 COEFFICIENT OF FRICTION OF LUBRICANTS: ASTM D5183EXPLANATIONThis test method can be used to determine the coefficient of friction of lubricating fluids under the prescribed test conditions using a Four-Ball Wear Test Machine.TEST SUMMARYThree steel balls are clamped together and covered with wear-in ...
  • CLOUD POINT OF PETROLEUM PRODUCTS: ASTM D2500 CLOUD POINT OF PETROLEUM PRODUCTS: ASTM D2500(Equivalent Test Methods: IP 219, ISO 3015, DIN 51597, JIS K 2269, and AFNOR T60-105)EXPLANATIONThe cloud point of a petroleum oil is an index of the lowest temperature of its utility for certain applications. Cloud point is the temperature at which a cloud ...
  • CLOUD POINT: ASTM D5771/ASTM D5772/ASTM D5773 CLOUD POINT: ASTM D5771/ASTM D5772/ASTM D5773EXPLANATIONThese three test methods are alternative procedures with automatic apparatus to Test Method ASTM D2500 (see next page). When specifications quote ASTM D2500, do not substitute these test methods without obtaining comparative data and customer agreement. ...
  • CHLORINE ORGANIC CHLORIDE IN CRUDE OIL: ASTM D4929 CHLORINE ORGANIC CHLORIDE IN CRUDE OIL: ASTM D4929EXPLANATIONOrganic chloride species are potentially damaging to refinery processes. Usually they are not known to be naturally present in crude oils and usually result from cleaning operations at producing sites, pipelines, or tanks. Hydrochloric acid ...
  • CHLORINE FIELD TEST KIT METHOD FOR CHLORINE IN USED PETROLEUM PRODUCTS: ASTM D53 CHLORINE FIELD TEST KIT METHOD FOR CHLORINE IN USED PETROLEUM PRODUCTS: ASTM D5384EXPLANATIONChlorinated compounds can corrode the equipment and poison the refining catalysts. They are also a health hazard when incompletely combusted. Federal regulations mandate that often the chlorine content of used ...
  • CHLORINE BOMB METHOD: ASTM D808 CHLORINE BOMB METHOD: ASTM D808GENERALThe knowledge of amount of chlorine containing compounds present in petroleum products can be used to predict performance or handling characteristics of the product.TEST SUMMARYThe sample is oxidized by combustion in a bomb containing oxygen under pressure. The chlorine ...
  • DERIVED CETANE NUMBER OF DIESEL FUELS OILS: ASTM D7170 DERIVED CETANE NUMBER OF DIESEL FUELS OILS: ASTM D7170EXPLANATIONThe ignition delay (ID) and derived cetane number (DCN) values determined by this test method can provide a measure of the ignition characteristics of diesel fuel oil in compression ignition engines. The relationship of diesel fuel oil ...
  • CARBONYL SULFIDE IN PROPYLENE BY GAS CHROMATOGRAPHY: ASTM D5303 CARBONYL SULFIDE IN PROPYLENE BY GAS CHROMATOGRAPHY: ASTM D5303EXPLANATIONIn processes producing propylene, COS usually remains with the C3 hydrocarbons, and must be removed since it affects the product quality. COS acts as a poison to commercial polymerization catalysts, resulting in deactivation and ...
