Certified Viscosity Standards

Fungilab offers a wide variety of certified viscosity standards for the calibration and verification of glass capillary viscometers, auto viscometers, rotational viscometers, flow cups and other viscosity measuring equipment.

Viscosity plays a critical role in the performance in different fields. Using a certified viscosity standard is essential for precise calibration and verification of viscosity measurements, ensuring the accuracy and reliability of analytical instrumentation.

All viscosity standards are traceable to the primary standard of pure water, having a Kinematic Viscosity of 1.0034 mm2/s at 20 °C, as adopted by National Metrology Laboratories such as NIST and national standard bodies like ASTM, IP and ISO. All certification is carried out in accordance with ISO 17025 and ISO 17034 accreditations.

General purpose viscosity standards

Fungilab ISO 17025 / ISO Guide 34 dual certified general purpose viscosity standards are tested in accordance with ASTM D 2162, (“Standard Practice for basic calibration of master viscometers and viscosity standard oils”).

They are fully traceable to national standards and are test equipment compatible.

General purpose silicone standards

Fungilab ISO 17025 / ISO 17034 dual certified Silicone Rotational Viscosity Standards are specifically formulated for use with rotational viscometers. Supplied in 600 mL ‘ready to use’ packs specially designed to eliminate the requirement to transfer the sample to a test beaker. Silicone viscosity standard fluids are most commonly used to verify calibration of Fungilab lab viscometers.
General purpose silicone fluids are the most commonly used standard for verifying calibration of your Fungilab  Viscometer. Silicone Standards are Newtonian fluids which are accurate to ±1% of viscosity value. Silicone fluids provide excellent temperature stability. Fungilab Viscosity Standards are certified by methods traceable to the United States National Institute of Standards and Technology (NIST).
