A high-frequency reciprocating rig for diesel lubricity evaluation using a loaded steel ball and test disc. The system combines controlled reciprocating motion, environmental control and optical wear-scar measurement with computer-based reporting.
Features
- Diesel lubricity evaluation to ASTM D6079 and ISO 12156-1.
- Controlled reciprocating frequency, stroke and applied load.
- Separate semiconductor temperature and humidity controller.
- Reflective optical encoder with real-time stroke display.
- Optical wear-scar measurement with X and Y readings.
- Image capture and computer-generated test reports.
- Stored test history and reference-oil calibration records.
Applications
Diesel fuel lubricity testing; additive performance studies; refinery quality control; tribology research.
