CANNON Low Temperature Viscosity Standards
ASTM D2983, SAE J300
Low Temperature Viscosity Standards (General Purpose, CCS and CMRV)
CANNON Low Temperature Viscosity Standards verify viscometer performance at subzero temperatures. These standards are applicable to SAE Specification J300 as well as a variety of ASTM Methods including:
• ASTM D2983, Low-Temperature Viscosity of Lubricants Measured by Brookfield Viscometer
• ASTM D3829, Predicting the Borderline Pumping Temperature of Engine Oil
• ASTM D4684, Determination of Yield Stress and Apparent Viscosity of Engine Oils at Low Temperature
• ASTM D6821, Low Temperature Viscosity of Drive Line Lubricants in a Constant Shear Stress Viscometer
• ASTM D6896, Determination of Yield Stress and Apparent Viscosity of Used Engine Oils at Low Temperature
• ASTM D5293, Apparent Viscosity of Engine Oils and Base Stocks Between –5 °C and –35 °C Using Cold-Cranking Simulator
The General Purpose Low Temperature Viscosity Standards in Table 6 are applicable to a variety of applications such as testing the viscosity of gear oils (SAE 70W, 75W, 80W and 85W) and automatic transmission fluids (ATF) per ASTM D2983 and SAE J300 with CANNON’s Thermoelectric Sample Conditioner System (TESC). Lot specific viscosity data is provided with each standard. Nominal viscosity values are shown in Table 6.
