For calibration of rotational viscometers
- Viscosity certified at 20, 23, 24, 25, 26 and 27°C
- Calibrated to a precision of ±0.2%
- NIST traceable
Standards are based on the National Institute of Standards and Technology (NIST) value of 1.0016 mPa-s (centipoise) for water at 20°C (68°F). Silicone standards sold in 500 mL bottles.
