ED-02
Our supply enquiry covers Group I, II and III base oils. We review the named grade, viscosity, packaging, quantity and destination with the proposed source. Product suitability and availability are confirmed in the quotation.
Grades & scope
Base stocks for lubricant blending, selected around your viscosity and formulation requirements.
Lubricant blending / Automotive oils / Industrial lubricants
Request the technical data sheet, safety data and batch-specific documents with your enquiry. Documents are confirmed for the proposed grade and source.
Technical selection notes
TECHNICAL / BASE OILS
A purchasing checklist, not a certificate of conformity. Agree the test method, edition, limits and sampling requirements; confirm results on the producer’s batch COA.
| Property | Method / unit | What the buyer should verify |
|---|---|---|
| Kinematic viscosity | ASTM D445 · mm²/s (cSt) | Specify both 40°C and 100°C, including an acceptable range. A viscosity number without its test temperature is incomplete. |
| Viscosity index · VI | ASTM D2270 · dimensionless | VI describes viscosity–temperature behavior. Compare it with the API group and formulation needs; it is not a viscosity grade. |
| Density | ASTM D4052 / D1298 · kg/m³ | State the reference temperature. Convert kg/m³ to kg/L by dividing by 1,000. Use batch density for the mass-to-volume loading calculation. |
| Pour point & cold behavior | ASTM D97 · °C | Request a maximum pour-point limit and any application-specific low-temperature tests. Pour point alone does not establish pumpability. |
| Flash point | ASTM D92 · °C | Keep the test method with the result. Flash point is not an approved storage or heating temperature; handling follows the supplier SDS. |
| Sulfur, saturates & cleanliness | API 1509 · % mass / agreed tests | Confirm sulfur and saturates for group classification. Separately agree water, contamination, appearance and additive-compatibility requirements. |
No. SN identifies a base-oil designation; SAE 15W-40 is a finished engine-oil viscosity grade. Ask for the actual base-oil viscosity and formulation requirements.
Litres = 1,000 ÷ density in kg/L. At an assumed 0.87 kg/L, one tonne is about 1,149.4 L. This is an arithmetic example, not a certified product density.
Request the producer TDS and SDS, proposed origin, batch COA arrangements, packing specification, quantity basis and named delivery place. Confirm availability and commercial terms in writing.
