ASTM D2983 Standard Test Method for Low Temperature Viscosity of Automatic Transmission Fluids, Hydraulic Fluids, and Lubricants

EUROLAB laboratory provides testing and compliance services within the scope of ASTM D2983 standard. This test method involves the use of rotary viscometers with a suitable torque range and special spindle for determining the low shear viscosity of automatic transmission fluids, gear oils, hydraulic fluids and some lubricants.

This test method was previously titled "Low Temperature Viscosity of Lubricants Measured by Brookfield Viscometer". In the lubricant industry, D2983 test results are often referred to as "Brookfield 2 Viscosity", which refers to a viscosity determined by this method.

This test method includes four procedures:

• Procedure A is used when only an air bath is used to cool samples in preparation for viscosity measurement.
• Procedure B is used when a mechanically cooled programmable liquid bath is used to cool samples in preparation for viscosity measurement.
• Procedure C is used when a mechanically cooled constant temperature liquid bath is used to cool samples via a simulated air cell (SimAir) 3 cell in preparation for viscosity measurement.
• Procedure D automates the determination of low-temperature, low-shear viscosity using a thermoelectrically heated and cooled temperature-controlled sample chamber in conjunction with a programmable rotational viscometer.

Values ​​stated in SI units should be accepted as standard. No other units of measurement are included in this standard.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.
