![]() 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™ 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 D 4212 but, in addition, each EZ 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. The new EZ Viscosity Cup Series is a logical and necessary outgrowth of the standardization studies on the Zahn Signature and similar cups for the promotion of this most popular type of viscosity measuring instrument as a national and international standard. 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 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 Cup orifices are machined rather than drilled to insure exact centering in the cup hemisphere base and a minimum of burr formation.The finest, most reliable, calibrated & documented cup on the market.The EZ Cup is not matched by any other cup of its type, either with respect to the advantages listed above, in highest quality of workmanship or in continuing quality control procedures.Calibration and Certification procedures qualify under ANSI/NCSL Z540-1 or MIL- STD- 45662A as applicable.EZ Cup calibration is traceable to the National Institute of Standards and Technology.EZ Cups are compatible to ASTM D 1084 Viscosity of Adhesives and ASTM D 816.Ĭonversion table relating efflux time in seconds, to the nearest tenth of a second, to viscosity in centistokes furnished with each EZ™ Cup.The EZ Cup formula for each cup of the series matches the applicable ASTM formula in D 4212 at the recommended calibration level.Oils used to standardize EZ Cups are produced in accordance with ISO 9002: 1984 EN 29002: 1984 BS5750 Part 2: 1984 ANSI/ASQC Q92: 1984.3% Guaranteed Tolerance Complies with & Exceeds ASTM D4212.Ovens / Drying & Heating Chambers / Climates Chambers.Type: made of stainless steel, with fixed stainless steel nozzle, orifice No. ![]() ![]() Optional: possible to certify by calibration with certified oils TQC Viscosity Cup ASTM D1084 D4212 Immersion Zahn TQC viscosity cups are made under the continuing quality control procedures.Įach cup is provided with an engraved unique serial number. ![]() The design of the cup and orifice eliminate hard to clean recesses. Ideal for measuring coatings and other fluids during application or production.Įach cup has a long handle to allow the cup to be dipped by hand into a liquid container, which makes it easy to quickly check and adjust the viscosity of many different type of liquids. The TQC Viscosity Cup ASTM D1084 D4212 Immersion Zahn is a range of stainless steel (SS303) viscosity cups with fixed stainless steel inner cavity nozzle and handle. ![]()
