  • WEAR CHARACTERISTICS OF LUBRICATING GREASE (FOUR BALL METHOD): D2266 WEAR CHARACTERISTICS OF LUBRICATING GREASE (FOUR BALL METHOD): D2266(Equivalent Test Methods: IP 239, ISO 11008, and DIN 51350)EXPLANATIONThe four ball wear test method can be used to determine the relative wear preventing properties of greases in sliding steel-on-steel applications under specific test ...
  • WEAR PREVENTIVE PROPERTIES OF LUBRICATING GREASES: D3704 WEAR PREVENTIVE PROPERTIES OF LUBRICATING GREASES: D3704EXPLANATIONThis test method is used to differentiate between greases having high, medium, and low wear preventive properties using Falex block-on-the ring friction and wear test machine.TEST SUMMARYThe tester is operated with a steel test ring oscillating ...
  • WEAR CHARACTERISTICS OF LUBRICATING FLUID (FOUR BALL METHOD): D4172 WEAR CHARACTERISTICS OF LUBRICATING FLUID (FOUR BALL METHOD): D4172EXPLANATIONThis test method covers a procedure for making a preliminary evaluation of the anti-wear properties of fluid lubricants in sliding contact by means of the Four-Ball Wear Test Machine. No attempt has been made to correlate this ...
  • WEAR CHARACTERISTICS OF NON-PETROLEUM AND PETROLEUM HYDRAULIC FLUIDS: D7043 WEAR CHARACTERISTICS OF NON-PETROLEUM AND PETROLEUM HYDRAULIC FLUIDS: D7043EXPLANATIONThis test method is an indicator of the wear characteristics of petroleum and non-petroleum hydraulic fluids operating in a constant volume vane pump. Excessive wear in vane pumps could lead to malfunction of hydraulic ...
  • WEAR CHARACTERISTICS OF PETROLEUM HYDRAULIC FLUIDS: D6973 WEAR CHARACTERISTICS OF PETROLEUM HYDRAULIC FLUIDS: D6973EXPLANATIONThis test method is an indicator of the wear characteristics of petroleum hydraulic fluids operating in a constant volume vane pump. Excessive wear in vane pumps could lead to malfunction of hydraulic systems in critical industrial or ...
  • WAX CONTENT OF CORRUGATED PAPERBOARD: D3344 WAX CONTENT OF CORRUGATED PAPERBOARD: D3344EXPLANATIONMany of the functional properties of wax-treated corrugated paperboard and cartons are dependent on the amount of wax present. In the case of the wax-saturated or wax-impregnated paperboard, the principle concern is with the weight of wax used relative ...
  • WAX APPLIED DURING CURTAIN COATING OPERATION: D3708 WAX APPLIED DURING CURTAIN COATING OPERATION: D3708EXPLANATIONWax coatings are applied to corrugated board to provide a barrier against moisture or other penetrates or to provide improved appearance or abrasion resistance. These functional properties are influenced by the amount of wax present on the ...
  • WAX APPEARANCE POINT OF DISTILLATE FUELS: D3117 WAX APPEARANCE POINT OF DISTILLATE FUELS: D3117EXPLANATIONWax appearance point is the temperature at which wax crystals begin to precipitate out of a fuel under specified cooling conditions. The presence of wax crystals in the fuel may restrict flow or plug the fuel filter. In critical fuel systems, ...
  • WATER WASHOUT CHARACTERISTICS OF LUBRICATING GREASES: D1264 WATER WASHOUT CHARACTERISTICS OF LUBRICATING GREASES: D1264(Equivalent Test Methods: IP 215, ISO 11009, and DIN 51807 T2)EXPLANATIONThis test method covers the evaluation of the resistance of a lubricating grease to washout by water from a bearing, when tested at 38 and 79° C (100 and 175° F) under ...
  • WATER UNDISSOLVED IN AVIATION TURBINE FUELS: D3240 WATER UNDISSOLVED IN AVIATION TURBINE FUELS: D3240EXPLANATIONUndissolved (free) water in aviation fuel can encourage the growth of microorganisms and subsequent corrosion in the tanks of aircraft and can also lead to icing of filters in the fuel system. The usual range of the test reading covers from ...
