ASTM D2983-09<\/h3>\n

Historical Standard: Standard Test Method for Low-Temperature Viscosity of Lubricants Measured by Brookfield Viscometer<\/h4>\n
\n

ASTM D2983<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers the use of Brookfield viscometers of appropriate torque for the determination of the low-shear-rate viscosity of lubricants. The test is applied over the viscosity range of 500 to 900 000 mPa\u00b7<\/span>s within a low temperature range appropriate to the capacity of the viscometer head.<\/p>\n

1.2 The range of viscosity used to generate the precision data for this test method was from 1000 to 900 000 mPa\u00b7<\/span>s. Appendix X4 lists another interlaboratory study that specifically targeted hydraulic fluid ranging from 500 to 1700 mPa\u00b7<\/span>s.<\/p>\n

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

1.3.1 The test method uses the SI unit, milliPascal-second (mPa\u00b7<\/span>s), as the unit of viscosity. (1 cP = 1 mPa\u00b7<\/span>s).<\/p>\n

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/span><\/p>\n
