This book was released on 1992 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to the Society of Automotive Engineers' (SAE) desire to introduce cold-cranking viscosity limits measured at temperatures specified for each W-grade of engine oil, the Co-ordinating European Council (CEC) joined ASTM in 1982 in determining a precision statement for the so-called "Multi-Temperature CCS Method". In 1990, CEC again collaborated with ASTM in a similar round-robin test which this time yielded a precision sufficiently encouraging for ASTM to ballot for Standard Test Method status. Two new techniques (differential scanning calorimetry and gas chromatography simulated distillation) differentiated between a limited population of good and poor industry pumpability reference oils. These techniques indicated that some model SAE 10W-30 oils blended from "critical" base oils could be potential pumpability problem oils despite acceptable borderline pumping viscosities in the Brookfield viscometric using the TP-1 cooldown cycle. The DSC and GC techniques are recommended as screening tests when developing new formulations. The development of a low-temperature oil pumpability test method employing the Brookfield viscometer in conjunction with the cooling cycle adopted in ASTM D4684-86 is described. Reference is made to a new, European-designed, high-precision viscometer for the measurement of low-temperature cranking viscosities.

Download or read book Development of ASTM Standard Test Methods for Measuring Engine Oil Viscosity Using Rotational Viscometers at High Temperature and High Shear Rates written by RB. Rhodes and published by . This book was released on 1989 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two ASTM standards have been developed for the measurement of engine oil viscosity at high temperature (150°C) and high shear rate (106 s-1) using rotational viscometers. Both methods resulted from significant international participation at the working group level. One test method resulted from work done primarily within ASTM Committee D-2, Subcommittee 7, using the tapered bearing simulator. The other resulted from work done within the Co-ordinating European Council (CEC) using the Ravenfield viscometer, herein called the tapered plug viscometer. The chronological development of each standard is reviewed, and test method and precision are compared. Expansion of measurement capabilities are discussed with regard to the study of lubricant rheology and engine performance.

Download or read book Development of an ASTM Standard Test Method for Measuring Engine Oil Viscosity Using Capillary Viscometers at High Temperature and High Shear Rates written by JM. Demko and published by . This book was released on 1989 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of a standard ASTM test method for measuring engine oil viscosity at high temperature (150°C) and high rate of shear (106 S-1) is discussed. A review is provided of the ASTM interlaboratory program that incorporated several different viscometer designs to evaluate a single generalized procedure for viscosity determination. A statistical analysis for ASTM repeatability and reproducibility resulted in a level of precision that approached that of rotational high-temperature, high-shear viscometers. Excellent correlation between capillary viscometers and rotational instruments is also demonstrated. The method is applicable to existing high-temperature, high-shear viscosity requirements in the European Committee of Common Market Automobile Constructors (CCMC) specification as well as individual high-temperature, high-shear specifications established by original equipment manufacturers.
