Oils used to standardize GARDCO Cups are produced in accordance with ISO 9002.Both GARDCO EZ & GARDCO S90/Zahn Signature dip cups qualify for Calibration Certification under ANSI/NCSL Z540-1 as applicable.All GARDCO cups are calibrated with standard liquids traceable to the National Institute of Standards and Technology.A wall size "Viscosity Cup Equivalent Chart" allows you to convert efflux times in seconds to viscosity in Centistokes for all 45 cups made and calibrated by Gardco.All GARDCO Cups can be calibrated and furnished with a set of Calibration Charts to convert seconds efflux time to viscosity in Centistokes.S90/Zahn Signature Dip Cups are calibrated within 5% tolerance.EZ Cups are calibrated to within 3% tolerance.GARDCO Cups give reliable, credible, accurate readings.Sets of graphs with flow curves detailing these differences are available on request. This will allow you to maintain the records you have established with your S90/Zahn Signature Dip Cups, and also enable you to invert to ASTM D 4212 readings if necessary, even though the cup Constants and Formulas for the S90/Zahn Signature Dip Cups differ from ASTM Specification D 4212. You can convert S90/Zahn Signature Dip Cup readings to ASTM D 4212 readings using the EZ to S90/Zahn Signature Seconds Conversion Charts by GARDCO.Only use CALIBRATED cups with a GARDCO (Paul N.
#Astm d 4212 update
Be sure to update your specification sheets and literature to include the type of Zahn cup (EZ or S90/Zahn Signature), the cup # and the efflux time in seconds. GARDCO S90/Zahn Signature Dip Cups are designed to meet the earlier specifications.
These two cups are the GARDCO S90/Zahn Signature Dip Cups and GARDCO EZ Zahn (ASTM) Dip Cups. We make two calibrated Zahn type cups that do differ in efflux time in seconds in order to meet both past and present specification requirements. Unfortunately, such cups were not calibrated which often resulted in variations of efflux time in seconds from cup to cup. Some original specifications were based on the early G.E. Differences of over 50% have been recorded.
Today these words can still be found in many technical specification sheets and literature, but today the phrase can be misleading, erroneous and meaningless because many makers have copied this cup and their efflux time in seconds can greatly differ from one make cup to another make cup, from one production run to another, as well as from one cup to another in the same lot.

#Astm d 4212 serial
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.
