2024年4月16日 · Note 2: ISO 3104 corresponds to Test Method D445 – 03. 1.2 The result obtained from this test method is dependent upon the behavior of the sample and is intended for application to liquids for which primarily the shear stress and shear rates are proportional (Newtonian flow behavior). If, however, the viscosity varies significantly with the ...

1.1 This test method specifies a procedure for the determination of the kinematic viscosity, ν, of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer.

The Class D.445 is a class of diesel locomotives used by the Italian Ferrovie dello Stato (FS) railway company and by Trenord. 150 units were built between 1974 and 1988, divided into three series. The D.445 represented an evolution of the FS Class D.443 locomotive, [1] maintaining the predecessor's reliability and operational capabilities.

ASTM D445 describes the standard test method to measure the kinematic viscosity ν (ny) of petroleum products according to ASTM International (formerly “American Society for Testing and Materials”, since 2001 "ASTM International").

This standard is issued under the fixed designation D445; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

2019年12月1日 · This practice covers the calibration of master viscometers and viscosity oil standards, both of which may be used to calibrate routine viscometers as described in Test Method D445 and Specifications...

Explain and execute correct procedures for sampling and preparing test specimens according to ASTM D445 standards. Demonstrate the correct procedure for calibrating a glass capillary viscometer. Perform calculations for analysis and accurately report results according to ASTM D445 guidelines.

2024年4月10日 · ASTM D445 determines the viscosity of liquid petroleum products by measuring the time for a liquid to flow under gravity through a viscometer at a closely controlled temperature. The kinematic viscosity is determined by calculation, and …
