  • ASTM D943 method for oxidation characteristics of inhibited mineral oils ASTM D943 method for oxidation characteristics of inhibited mineral oils3. Summary of Test Method3.1 The oil sample is contacted with oxygen in the presence of water and an iron-copper catalyst at 95°C. The test continues until the measured acid number of the oil is 2.0 mg KOH/g or above. The number ...
  • ASTM D943 method for oxidation characteristics of inhibited mineral oils ASTM D943 method for oxidation characteristics of inhibited mineral oils1. Scope1.1 This test method is used to evaluate the oxidation stability of inhibited steam-turbine oils in the presence of oxygen, water, and copper and iron metals at an elevated temperature. The test method is also used for testing ...
  • ASTM D524 method for Ramsbottom carbon residue of petroleum products ASTM D524 method for Ramsbottom carbon residue of petroleum products11. Calculation and Report11.1 Calculate the carbon residue of the sample or of the 10 % distillation residue as follows:Carbon residue = (A x 100)/Wwhere:A = mass of carbon residue, g, andW = mass of sample, g.11.2 Report the value ...
  • ASTM D524 method for Ramsbottom carbon residue of petroleum products ASTM D524 method for Ramsbottom carbon residue of petroleum products9. Procedure9.1 Place a new glass coking bulb (Note 12) in the coking furnace at 550°C for about 20 min to decompose any foreign organic matter and to remove water. Place in a closed desiccator over a suitable desiccant, such as a desiccant ...
  • ASTM D524 method for Ramsbottom carbon residue of petroleum products ASTM D524 method for Ramsbottom carbon residue of petroleum products6. Apparatus6.1 Glass Coking Bulb, of heat-resistant glass conforming to the dimensions and tolerances shown in Fig. 1. Prior to use, check the diameter of the capillary to see that the opening is greater than 1.5 and not more than 2.0 ...
  • ASTM D524 method for Ramsbottom carbon residue of petroleum products ASTM D524 method for Ramsbottom carbon residue of petroleum products4. Summary of Test Method4.1 The sample, after being weighed into a special glass bulb having a capillary opening, is placed in a metal furnace maintained at approximately 550°C. The sample is thus quickly heated to the point at which ...
  • ASTM D524 method for Ramsbottom carbon residue of petroleum products ASTM D524 method for Ramsbottom carbon residue of petroleum products1. Scope1.1 This test method covers the determination of the amount of carbon residue (Note 1) left after evaporation and pyrolysis of an oil, and it is intended to provide some indication of relative coke-forming propensity. This test ...
