- Each oil comes with a calibration certificate giving viscosity measurements at 20, 23 and 25°C.
- The oil is produced in a laboratory accredited to ISO 17025 and ISO Guide 34 using primary laboratory test equipment giving improved levels of uncertainty.
- Calculated viscosity at temperatures at 0.5°C intervals between 20 and 25°C and a calibration graph are included on the certificate.
Viscosity Products
500ml Oil bottles
Ideal for calibrating equipment or flow cups at any temperature between 20 and 25°C.The certificate supplied with each oil can include the flow time of the oil through a specified flow cup at temperatures from 20 to 25°C in 0.5°C steps.
Each Viscosity Calibration Standard Oil is supplied in a 500 ml container together with a certificate showing that the calibration is traceable to the International Standard ASTM D2162. The calibration certificate quotes viscosity in mm²/s (centistokes), mPa.s (centipoise) and (where applicable) Krebs units.
If you require any further information please contact us.
Calculation of Flow Time
We can also calculate the flow time of the oil through a specified flow cup at 0.5°C intervals between 20 and 25°C. This chart is purchased separately. Please contact us and specify which oil and flow cup the chart is required for.
