The Applied Technical Services Family of Companies (ATS FoC) uses ASTM D1403 to measure the consistency of lubricating grease using one-quarter and one-half-scale cone equipment, making it ideal for testing small or reduced samples. This method delivers reliable penetration values equivalent to full-scale results, providing clients with accurate data to verify product quality and assess suitability for lubrication applications, even when limited material is available.
Why Is ASTM D1403 Important for Evaluating Lubricating Grease?
We primarily use ASTM D1403 to classify lubricating grease consistency, indicating whether the grease is too soft, too hard, or within the specified range for its intended application.
Grease consistency directly affects:
- Resistance to Deformation Under Load
- Lubricant Pumpability
- Retention in Bearings and Mechanical Systems
- Gears, Electric Motors, and Machinery
- Sealing Capability
- Wear Protection
- Overall Lubrication Performance
- Equipment Reliability
- Service Life
- NLGI Drade Determination
How Is the ASTM D1403 Test Performed?
In a controlled environment, our experts conduct the ASTM D1403 test by measuring the penetration depth of a standardized cone into a grease sample using quarter- or half-scale equipment. The results are converted to full-scale equivalents for direct comparison with industry-specific standards. This data supports quality control, condition monitoring, lubricant qualification, and failure analysis.
