Verification at least once a month is recommended. Warning— Measurement of vacuum operating pressure is one of the two FIG. A frequency of at least once a week is recommended. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. By feeling for the spillover point, the distance from the top joint of astj adaptor can be found.

This wettage may be treated as a separate fraction and its density estimated or blended into the residue before inspections are made. ASTM D distillation of heavy axtm mixtures: A suitable leak test is to pump down to a pressure below 0. Summary of Test Method 4. Harmful or fatal if inhaled or ingested.

De Nemours and Co. The lighter products produced in this process are further refined in various refinery processes. Precision and Bias If, after 1 min, the rise in pressure is no greater than 0. Reduce the pressure slowly to a level that will allow for a reasonable amount of overhead product to evolve at the new pressure level.

Crude Oil Assay Tests List

Verification of the calibration of the sensors can be accomplished potentiometrically by the use of standard precision resistance or by distilling a pure compound f5236 accurately known boiling point, as described in A2. It is most important that at the time of first use of a new apparatus, its components be checked as detailed in Annex A1 and Annex A2 and that the location of the vapor temperature sensor be verified as detailed in 6. It employs a potstill with a low pressure drop entrainment separator operated awtm total takeoff conditions.


Size px x x x x The K-factor shall be assumed to be 12 and any effect of K-factor ignored unless there is mutual agreement to the contrary. In the case of ball joints, use only enough lubricant to produce a thin continuous film.

Crude oil axtm petroleum quality expertise: Allow the system to stabilize for at least 2 min.

ASTM D – Pilodist

The crude oil is heated and separated by the distillation column into lighter products such as; gasoline, kerosene, naphtha, etc. Use Caution d55236 handling mercury and mercury-containing products. Steel flasks can have a cooling coil for rapid quenching of the distillation in an emergency.

It is recommended that these stills be kept in an enclosure to ensure that in case of an implosion, the operator and others nearby are protected from flying debris, but that the front, at least, be transparent and removable for access to controls and so forth. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world.

The dimensions and tolerances of such a gage are beyond the scope of this test method. The total must be between While the practice of reblending distillates v5236 residue can be done to produce a lighter residue, it is not recommended because it produces blends with irregular properties.

It is NOTE 4—Cracking will significantly affect the quality of the cuts and the residue, for example, the densities and viscosities would be significantly lower than those obtained without cracking.

Secondary gages shall be recertified at a regular basis, but at least once a year.

Home Astm d Astm d January 31, Author: Automatic or manual control can be used. The ASTM D method of distillation employs a vacuum pot still with a low pressure drop entrainment separator operated under total takeoff conditions.

Alternatively, certified sensors may be used, provided the calibration of the sensor and its associated recording instrument can be traced back to a primary temperature standard. Do not take any cuts until the pressure has asym at the new level for at least 2 min. Dry d536 air and replace it. When the curve exhibits a plateau of constant temperature for longer than 1 min, the temperature of the recorded plateau is accepted as the calibration temperature.
