Iso Oil Chart

Iso Oil Chart - The viscosity grade of a lube oil is determined by the society of automotive engineers (sae). The higher the number, the thicker the oil. In order to check engine oil viscosity grades click sae j300 along with sae j306 for gear oil. Viscosity table/chart as per iso 3448 for industrial fluids. Iso vg2 2,2 1,98 2,42 iso vg3 3,2 2,88 3,52 iso vg5 4,6 4,14 5,06 iso vg7 6,8 6,12 7,48 iso vg10 10 9,00 11,0 iso vg15 15 13,5 16,5 iso vg22 22 19,8 24,2 iso vg32 32 28,8 35,2 iso vg46. Web chart/table provided below for agma gear oils (lubricants) only. Oils can be separated into multigrade oils and monograde oils. This is because the iso specifications are broad, and they overlap with sae weights in some cases. This eliminates spring and fall oil changes. Different approaches were thoroughly considered before the iso technical.

Listed Below Them Are The Viscosity Grades For These Standards.

Basically, it allows users to determine whether or not lubricants will have similar viscosities. Iso 46 oil’s optimal viscosity guarantees efficient lubrication for hydraulic components, forming the protective film that is applied to metal surfaces that reduce wear. The higher the number, the thicker the oil. Web iso/ agma/ sae viscosities.

Kinematic Viscosity At 40°C Max.

Please note that ep, r&o and c (compound) designations are no longer used. Below is a chart outlining the viscosity grades defined by sae j306. Oils will have a steeper slope. Web viscosity at 20°c/68°f and 50°c/122°f for more than 120 crudes is shown as function of specific gravity@15°c/60°f.

You May Notice That Iso 46 Can Replace Both 15W And 20W Sae Oils.

The iso system is primarily used for hydraulic oil, industrial oils, such as turbine oils, compressor oils and others. This is because the iso specifications are broad, and they overlap with sae weights in some cases. It uses a number followed by vg to indicate viscosity, such as iso vg 32 or iso vg 68. Former agma viscosity classification for gear oils.

Web 22 Rows Iso Vg Are Based On Kinematic Viscosity Of The Lube Oil/Fluid At 40°C.

The viscosity ranges for agma lubricant numbers correspond with those of astm d2422 and iso 3448. Web the sae 70w, 75w, 80w and 85w are for low temperatures, and the sae 80, 85, 90, 110, 140, 190 and 250 are for the high heat applications. While you’d usually deal with sae oil grades, you can read the viscosity of engine oils of iso and agma oil grades using the viscosity chart. Web the purpose of the iso system of classifying viscosity grades is to establish a viscosity measurement method so that lubricant suppliers, equipment designers and users will have a common (standardized) basis for designating or selecting industrial liquid lubricants.
