General purpose viscosity reference standards

Paragon Scientific offer viscosity reference standards that are certified in strict accordance with ASTM D2162, the primary method for viscosity standards manufacture. Dual  certified to the International Standards BS EN ISO / IEC 17025 and ISO 17034 under our UKAS accrediatation. Paragon test at primary level using master viscometers in accordance with ASTM D2162 to ensure the lowest uncertainty of measurement thus providing standards that are certified with primary level accuracy. ASTM D2162 is the only referenced method for the certification of viscosity standards when adopting ASTM test method protocol.

Paragon’s standards are certified according to ISO 17025 / ISO 17034 under their UKAS accreditation and certified in strict accordance with ASTM D2162. The density is g/mL in accordance with ASTM D1480 and these are fully traceable to national standards. These standards are for use with glass capillary viscometers, automatic viscometers and other viscosity measuring equipment. The standard temper evident security packaging size is 500mL,but it is also available in 5L packs – and other sizes are available on request. Kinematic (cSt) and dynamic viscosity (mPa·s) given at all temperatures.
