This table is particularly useful in determining efflux time in seconds when viscosity in centistokes is known.įor those users who require documented certification of their measuring equipment, the EZ™ dip cups may be ordered, at an additional charge, with a CERTIFICATE of CALIBRATION. Not only has this cup been improved with respect to earlier produced cups and designed to comply to the requirements of ASTM D4212 but, in addition, each EZ Viscosity Dip Cup is furnished with a table which permits conversion between efflux time in seconds to the nearest tenth of a second to viscosity in centistokes.
#Din 4 viscosity cup series#
The EZ Viscosity Cup Series is a logical and necessary outgrowth of the standardization studies on the Zahn Signature Viscosity Cup and similar cups for the promotion of this most popular type of viscosity measuring instrument as a national and international standard. Viscosity Cups are non-returnable items.The increased separation width of the support rods by over 20% and the lowering of weld to the cup provide best possible conditions for cleaning.This eliminates errors due to test material drainage from support surfaces. The EZ Viscosity Cup support rods are offset from the side of the cup and secured to the cup sidewall below the cup rim.This insures an orifice of specified length and a correct symmetrical efflux stream. EZ Dip Cup orifices are machined rather than drilled to insure exact centering in the cup hemisphere base and a minimum of burr formation.Conversion table relating efflux time in seconds, to the nearest tenth of a second, to viscosity in centistokes furnished with each EZ™ Dip Cup.3% guaranteed tolerance for EZ Viscosity Cups complies with & exceeds ASTM D4212.Calibration and Certification procedures qualify under ISO/IEC 17025 as applicable.
