It assumes 96 VI single grade oils. endobj Example: An SAE 40 weight engine oil falls within the range of an ISO 1 50, the low end of an SAE 90 gear oil and an AGMA 4. Using a pattern that had some sense of repeatability up and down the scale. Found inside â Page 319The TOW Method The temperature ranges for the viscosity grades that appear in the TOW chart , figure 6 , are based upon the calculated temperatures for which a mid - range ISO VG , 100 VI hydraulic fluid has a viscosity between 13 and ... TABLE 3 - ISO Viscosity Grades for Industrial Oils (3) ISO Viscosity Grade Kinematic Viscosity at 40°C, Min cSt Kinematic Viscosity at 40°C, Max cSt 2 1.98 2.42 3 2.88 3.52 5 4.14 5.06 7 6.12 7.48 10 9.00 11.0 15 13.5 16.5 22 19.8 24.2 32 28.8 35.2 46 41.4 50.6 68 61.2 74.8 100 90.0 110 150 135 165 220 198 242 320 288 352 460 414 506 680 . Found inside â Page 183Because our DN value (9000) is a bit off the chart, enter the three-dimensional graph at the nearest valueâDN= 15,000, for instance. 4. ... Comparison charts show its international equivalent as ISO viscosity grade 320 [1]. Found inside â Page 315Here, in addition to their efficiency in reducing fluid viscosity increase and acidity development (which are the two most common ... Typical limits on mineral turbine oil would be >350 min for ISO 32 or 46 grade products (ASTM D 4304). Model # 106128 UNSPSC # 15121504 Catalog Page # 2455 2455 Country of Origin USA. This ISO viscosity classification is consequently based on kinematic viscosity at 40ºC (104ºF). Found insideLubrication charts: Plant Engineering Magazine is publishing âExclusive Guide to Synthetic Lubricantsâ and âInterchangeable ... Included is a chart titled âViscosity/Grade Comparison Chartâ that tabulates viscosity equivalents for ISO ... Lubricants Viscosities Equivalent Iso Vg Grade. Think of a water-skier cutting through the water. Viscosity Conversion for Newtonian Fluids. If the practitioner is comfortable with one particular measure but would like to see the correlating viscosity range in another measure, all he must to do is place a straight horizontal line through his chosen viscosity type and see its correlation within the other types of measures. This is similar to the amount of time it takes a specific volume of fluid at a specific temperature to drain through a funnel. Found inside â Page 516Table 9 A Trade Publication's Chart of Synthetic Lubricants ISO Viscosity Grade Viscosity , SUS at 100 F Keystone Lubricants Kluber Lubrication North America Kent Oil Lubrication Engineers Leahy - Wolf Lockrey 9455 Syn F - R Hyd Fluid ... Found inside â Page 323These list the type of lubricant according to DIN 51 502, ISO 6743, and ISO 3498 for each viscosity grade by its brand name. ... For most machines, a maintenance plan and a lubrication chart are included in the service handbook. At least for automotive oils, we can expect to continue to see the 10- 20- 30- 40- 50- values used. The most recent release in 1992 (ISO 3448) contains 20 gradients. If a machine is heavily loaded then the machine designer will use a lubricant that resists being pushed around, which would be heavy like honey. The classification is based on a series of viscosity grades, each being approximately 50% more viscous than its preceding grade, while the viscosity deviation within a grade is plus or minus 10% of the nominal viscosity .
