A variety of ASTM tests for specific lubricants are available. These include ASTM D2272 Rotating Bomb Oxidation Test, ASTM D2274 Oxidation Stability, ASTM D3223 Nitrogen Content for turbine oils. Dissolved Gas Analysis, under ASTM D3612 for transformer oils, can also be ordered. Basic testing for compressor lubricants includes spectrochemical analysis and physical properties tests for viscosity, acidity and moisture. Refrigerant and compressor lubricant services are useful in equipment surveys, in preventive maintenance programs, and for system conversions to R134A refrigerants .
Several help ensure warranty coverage.
As lubricants begin to degrade from normal operations, other testing pinpoints specific conditions and remedies. Analysts also offers complete ASTM analysis of grease to monitor contamination levels, degradation characteristics, and wear rates. Analysts is one of a select few testing organizations capable of measuring elements in absolute values. Any lab can measure relative values. Absolute values provide a more definitive evaluation of wear rates and physical properties.
