For specific warnings, see 6. Distillation conditions and equipment performance criteria are specified and typical apparatus is illustrated. The latter must be done if the residue is to be analyzed for other than density.
For larger stills, follow instructions given in Annex A5. 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.
A heat density of 0. Automated stills, which are left unattended for long periods, should be equipped with an automatic fire extinguisher, automatic quench, and alarm. Vacuum gages based on hot wires, radiation, or conductivity detectors are not recommended.
This can be used for interpolation when necessary. In addition, it provides for the determination of standard distillation curves to d52366 highest atmospheric equivalent temperature possible by conventional distillation. Isolate the pump and the bleed valve. Formally confirming that your products and services meet all trusted external and qstm standards.
Home Astm d Astm d January 31, Author: This test method details procedures for the production of a liquefied gas, distillate fractions, and resid of standardized quality on which analytical data can be obtained, and the determination of yields of astmm above fractions by mass and volume.

Examples of a distillation report and record are illustrated in Fig. Fit the distillation flask with a capillary line for the passage of nitrogen into atsm liquid. Verification of the calibration of the sensors can aetm accomplished using the procedures described in A2.
The recommended loading factor is between and mL of charge per square centimetre of cross sectional area in the neck of the head.
Reducing the skin temperature may be necessary in these cases. Cuts are taken at preselected temperatures. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Crude Oil Assay Tests List
The external magnetic drive must be capable of rotating the bar in the flask when located directly below and touching the mantle. A basic calibration procedure is described in A2. The ASTM D method of distillation employs a vacuum pot still with a low pressure drop entrainment separator operated under total takeoff conditions.
Warning—Ensure that the safety shield is in place. This will take 2 to 10 min depending on the amount of material in the flask. For the boiling point of water, use an equilibrium still or ebulliometer, a Tensimeter as shown in Fig. Evaporate the solvent in a hood assisted by a stream of air and weigh directly. Warning— Measurement of vacuum operating pressure is one of the two FIG. Estimating that the difference between the vapor and the pot temperature remain relatively constant, determine if the final vapor temperature can be achieved at this pressure while remaining within the recommended limitations of the flask d523 see 9.
Subsequent lowering asmt the operating pressure, as described above, has yielded satisfactory results. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
A pressure reduction by a factor of five or six adtm been shown to be necessary to produce a viable quantity of overhead at the new pressure level. While the practice of reblending distillates with residue can be done to produce a lighter residue, it is not recommended because it produces blends with irregular properties.
Last previous edition approved in as R5236 — By feeling for the spillover point, the distance from the top joint of the adaptor can be found. Distillation conditions and equipment performance criteria are specified and typical apparatus is illustrated.
Significance and Use 5.
It shall have a response time of less than 60 s as described in Annex A1.
