CCS Cold Cranking Simulator (ASTM D5293)

What is CCS(Cold Cranking Simulator)?

The Cold Cranking Simulator (CCS) measures the apparent viscosity of oils at temperatures from –35°C to –5°C, the cold cranking viscosity of used synthetic oils originating from vehicles operated under similar driving conditions. It is a high shear method and is designed to simulate the oil viscosity under cold starting (cranking) conditions. The reference standard is ASTM D5293.

Test Significance of CCS?

The low temperature cranking viscosity is one of the four basic viscosity measurements in SAE J300 which defines the rules around engine oil viscosity grades. It is necessary to measure the CCS value of every formulated engine oil in order to check that it is within the viscosity grade.

How to Work?

The CCS contains a temperature controlled pot test chamber. The motor controlled stator is housed within the chamber. The CCS uses a vacuum pump to inject the test sample into the test chamber, where it is cooled to the required test temperature. A motor stator with a constant current is started. The resistance of the stator in the sample at the test temperature is converted into viscosity in mPa.s.

Typical Parameters of CCS:

1.Applicable standards: GB/T6538, ASTM D2602, D5293

2.Refrigeration method:semiconductor refrigeration

3.Circulation mode: cooling water circulation

4.Temperature control mode:PID temperature controller

5.Detection method: automatic test, automatic injection, automatic cleaning

6.Result processing: automatic storage and printing

7.Test temperature:-5℃, -10℃, -15℃, -20℃, -25℃, -30℃, -35℃, -40℃

8.Working power supply: AC220 V, 50Hz
