FILTERABILITY OF ENGINE OILS AFTER TREATMENT WITH WATER AND DRY ICE: ASTM D6795
EXPLANATION
See ASTM D6794 regarding the significance of this test method.
TEST SUMMARY
The test oil is treated with deionized water and dry ice, and is heated for 30 min at 70° C, followed by storage at room temperature. The sample is filtered and the flow rate is calculated determining the engine oil filterability characteristics.
TEST PRECISION
Repeatability: 11.4 %
Reproducibility: 23.6 %
This precision estimate is based on use of 15 m filter results. Since there is no accepted reference materials suitable for determining the bias of this test method, bias cannot be determined.
