RViscosity Cup Conversion ChartThe table below lists the major flow cup types together with a conversion chart of Efflux Time (in seconds) toViscosity in Centistokes (cSt). It has been constructed from the various International Standard Calculators.Each cup design is unique and care must be taken when comparing viscosity values between different cuptypes. These values are the absolute values and do not include the allowed tolerances, as these differconsiderably between each of the Standards.Viscosity Cup 93ISO34ZAHNFORD / 72146342731.083.52235149692422All measurements are in Centistokes (cSt).

RViscosityViscosity is perceived as ‘thickness’ or resistance to pouring, but there ismore to viscosity than this. All fluids have an internal friction betweenmolecules, which determines how well fluid flows. Due to this internalfriction, energy is required to move the liquid and viscosity is the measureof the resistance to flow.Fluids are categorised as Newtonian or non-Newtonian. Newtonian fluids, such as water and some oils, are fluids thatcontinue to flow at a given temperature, regardless of the forces actingon it. No matter how fast it is stirred or mixed, Newtonian fluids willalways behave in the same manner. Newtonian fluids are generallymeasured with flow and dip viscosity cups. Non-Newtonian fluids, such as paints and ketchup, are fluids whichchange viscosity when a force is applied. There are several differentcategories and sub-categories of non-Newtonian fluids, they can bedescribed as the following:Thixotropic - substances which are gel-like at rest but liquid whenagitated, eg: non-drip paints, tomato ketchup and most varieties ofhoney.Rheopectic - substances where viscosity increases with duration ofstress, eg: some lubricants.Pseudoplastics - also known as shear thinning - the viscositydecreases with increased shear rate, eg: blood, gelatin and clay.Dilatant - also known as shear thickening - the viscosity increases withincreased shear rate, eg: suspensions of rice, corn starch orconcentrated sugar solution.Measuring ViscosityNon-Newtonian fluids are measured using Rotational viscometers(please see pages 19-25).Elcometer manufactures and supplies a wide range of viscosity gaugesfrom flow cups to dip cups to rotational viscometers. Flow Cups: The process of flow through an orifice can often be used asa relative measurement and classification of viscosity. This measuredkinematic viscosity is generally expressed in seconds of flow timewhich can be converted into Centistokes using a viscosity disccalculator. (See table opposite). Dip Cups: Using the same principle as flow cups, dip cups - Frikmar,Zahn, Shell etc. - can be used to provide a quick viscosity measurementeither on-site or on the shop-floor. Rotational: Rotational viscometers are used to determine the viscosityof liquids which do not depend solely on temperature and pressure. Flow Measurement: Simple to use instruments that measure thefluidity and flow of coatings, especially thick or paste-like materials.9www.elcometer.com

ViscosityRElcometer Viscosity Dip CupsElcometer viscosity dip cups are ideal for the quick testing of the viscosity of paints, varnishes and similar productsduring manufacturing processes.Dip cups are dipped into the substance being tested and the viscosity is determined by the time it takes for the cup toempty with a steady flow.Elcometer has a range of viscosity dip cups which includes Frikmar, Zahn, Shell, and Lory dip cups.Elcometer Frikmar Viscosity Dip CupsThanks to its handle, this cup is very easy to use to perform checks on site orduring the manufacturing process. It is ideal for measuring the consistency ofpaints, varnishes and similar products.The cup is first dipped into the product to be measured, then the contents emptythrough the orifice. The measured kinematic viscosity is generally expressed inseconds (s) flow time, which can be converted to Centistokes (cSt) if theStandard stipulates a conversion method.Several ranges are available, according to the Standards being used;from 7 to 1100cSt.certificateavailableTechnical SpecificationDIN Viscosity Dip CupsCup NumberDescriptionPart Number2K0002434M001 Elcometer 2434/1 DIN Dip Cup4K0002434M002 Elcometer 2434/2 DIN Dip Cup6K0002434M003 Elcometer 2434/3 DIN Dip Cup8K0002434M004 Elcometer 2434/4 DIN Dip Cup2 (d)K0002434M001C Elcometer 2434/1 with calibration certificate4 (e)K0002434M002C Elcometer 2434/2 with calibration certificate6 34M003C8 (d)K0002434M004C Elcometer 2434/4 with calibration certificate1Orifice Diameter2mm / 0.079”4mm / 0.158”6mm / 0.236”8mm / 0.315”2mm / 0.079”4mm / 0.158”6mm / 0.236”8mm / 0.315”Range (cSt)96 - 68396 - 683-Orifice Diameter4mm / 0.158”4mm / 0.158”Range (cSt)170 - 37070 - 370Can be used in accordance with: (see Standards Explained inside Front Cover)DIN 53211 (cup 4 only)FORD/ASTM Viscosity Dip CupsCup NumberDescriptionPart Number4K0002435M001 Elcometer 2435/1 FORD/ASTM Dip Cup4 (e)K0002435M001C Elcometer 2435/1 with calibration certificateCan be used in accordance with: (see Standards Explained inside Front Cover)ASTM D 1200(1) For Information Only(d) Dimensional Certificate(e) Efflux Time Certificate10www.elcometer.com
