General Viscosity Standards

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 Guide 34 under our UKAS accrediatation. The products are tested 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.
