The method of claim 13wherein the source of power is alternating current.
ASTM D938 – 12(2017)
In some embodiments, the method also includes repeating steps a – j. The apparatus includes a motor having a rotatable shaft extending horizontally therefrom; clamp for mounting the sample flask thereto, the clamp operatively connected to the rotatable shaft; and a temperature sensor for determining sample temperature over time. By the term “Fischer-Tropsch product” is meant a synthesis product of a Fischer-Tropsch process.
Hydrotreating of fischer-tropsch derived feeds prior to xstm using an ionic liquid catalyst. The apparatus of claim 1further comprising a housing for mounting the motor within. The method of d9388 11, further comprising repeating steps a – j. Caution should be taken when handling mercury and mercury containing products. Mercury, or its vapor, may be hazardous to health and corrosive to materials. A method for determining the congealing point of a wax-containing sample is also provided.

ASTM Proficiency Testing Programs PTP are statistical quality assurance programs that enable laboratories to assess their performance in conducting test methods within their own laboratories when their data are compared against other d9388 that participate worldwide in the same program.
The product was separated in a fraction L which is in the gas phase at ambient conditions and a fraction M which is in the solid phase at ambient conditions. Products from one manufacturer may satisfy one particular application, while product from a similar process will not work well.

Tropsch derived waxes is for example described on page in the r938 of Commercial Catalysts. A paraffin wax according to any one f938 claims 1 to 3, having a Saybolt colour according to ASTM D of at least 30 cm. The apparatus of claim 1wherein the motor is structured and arranged to rotate the clamp at a speed of less than 50 RPM.
EP EPA1 en In one aspect, disclosed herein is an apparatus for determining the congealing point of a wax-containing sample, such as a petroleum wax-containing sample, the sample placed within a sample flask, comprising: As shown, the clamp 16 is operatively connected to the rotatable shaft 14 of the motor Process to prepare a catalytically dewaxed gas oil or gas oil blending component.
CN CNA en The average of each determination is compared to the value obtained from conducting the traditional ASTM D method. In another aspect, disclosed herein is a semi-automated method for determining the congealing point of a wax-containing sample, such as a petroleum wax-containing sample.

The apparatus of clause 3, further comprising an indicator to indicate when power is supplied to the motor. Power is supplied to apparatus 10 across nodes Need more than one copy?
Product Description Prowax is a high-range melting point product in the Prowax line of petroleum slack and scale waxes. The apparatus was kept on a lab bench and the thermometer was leveled with aetm to the ground. Prowax is a high-range melting point product in the Prowax line of petroleum slack and scale waxes.
D9388 carefully remove the thermometer from the specimen, taking care to retain a relatively large drop of specimen adhering to the bulb.

Standard Test Method for Congealing Point of Petroleum Waxes, Including Petrolatum
These risks include the handling of hot glassware for an extended period, often three to eight consecutive minutes, depending on the sample; the use of a liquid-in-glass thermometer for an extended period; and the possibility of incurring a repetitive stress injury RSI risk, if multiple samples are to be tested. Using the semi-automatic apparatus eliminated the constant wrist movement while testing, requiring the operator to only prepare the apparatus and record the result.
