Viscosity index astm12/17/2023 Temperature control range: adjustable within 0100C 2. REMADE in ITALY ® was created to promote a more sustainable Italian industry, in partnership with the Ministry of the Environment. ASTM D445 Petroleum Products Kinematic Viscometer And Viscosity Index Meter 1. The label describes the characteristics of environmental sustainability of the material, process and product, in terms of raw materials and energy saving, and the reduction of CO2 emissions. Itelyum Regeneration regenerated bases possess the REMADE in ITALY ® certification, the first certification mark for products and materials deriving from recycling and reuse. Itelyum Regeneration lubricant base oils comply with the provisions of REACH regulation. In particular, if requested, Itelyum Regeneration process technology can produce lubricant base oils of the same viscosity, but with characteristics that classify them into API Group II, with sulphur content lower than 300 ppm and unsaturates content lower than 10%. ASTM D2270, Standard Practice for Calculating Viscosity Index From Kinematic Viscosity at 40 and 100☌. The viscosity index according to DIN 2909 is calculated by comparing the change in viscosity of an oil with the two oils as a reference. The Viscosity Index Test is based on the kinematic viscosity of the fluid at 40☌ (104☏) and 100☌ (212☏). The guide also provides workers with basic principles of each measurement approach and how to conduct them.įor more information, visit viscosities are available on request. ASTM D445, Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and the Calculation. Kinematic viscosity, measured using ASTM D445 methodology, determines an SAE oil’s high-temperature or operating temperature viscosity rating the 30 in 5W-30 motor oil. This was traditionally done by measuring the same sample with two different capillaries at those two temperatures in two different baths sequentially. Kanar notes that the new standard contains practical, historical and relevant information on how to measure the in-service lubricant viscosity. To determine the viscosity index according to the current ASTM Standard Practice D2270, it is required to measure the viscosity of the lubricant oil at 40 ☌ and at 100 ☌. "If viscosity is too low, the lubricant may not be able to protect the machine from premature wear of components." "If the viscosity is too high, it might exceed the pumping capabilities, and lubricant may not be able to reach critical components," says ASTM International member Norm Kanar, marketing and sales manager at Savant Labs. 3 For referenced ASTM standards, visit the ASTM website, or contact ASTM Customer Service at. Viscosity can affect the energy and mass transfer of the lubricant in the machine. 2 Supporting data (Metrication of Viscosity Index System Method D 2270) have been led at ASTM International Headquarters and may be obtained by requesting Research Report RR: D02-1009. ASTM developed test methods to estimate the Viscosity Index of an oil and updated it over the years (ASTM D2270-04 2004). Generally, proper lubrication is important for maximizing the usable life of a machine or device. With these benchmarks, a Viscosity Index could be assigned to any oil that was directly related to the value of the oil. The ASTM International committee on petroleum products, liquid fuels and lubricants (D02) recently created a new standard (to be released as D8185) that will serve as a guide for determining how to measure the viscosity of in-service oil.Īccording to the committee members, anyone with a technical background in lubrication or condition monitoring can use this guide to determine options for viscosity testing. The viscosity index is not defined and shall not be reported for oils with kinematic viscosity of less than 2.0 mm2/s at 100 C.
