Seeking standards related to the physical properties of lubricants
Thread Content
What are some relevant standards regarding the properties of lubricating oils? These are the physical properties required for designing lubricant storage tanks. I would like to ask **all of you; it would be better if you could send it over. I see there is an ISO classification for industrial lubricants, including viscosity grade, intermediate viscosity value (at 40°C, mm2/s), range of kinematic viscosity (at 40°C, mm2/s), minimum value, and maximum value. For ISO VG 2, these values are 2.2, 1.98, 2.42… I’m not sure what the code for this standard is I want to download it. Are there any other physical properties? Things like ignition point and flash point – are there any relevant standards? Any standard will do; it would be even better if one standard covered everything. Also, I’m looking for information on GB/T 7631.1-2008 \"Classification of lubricants, industrial oils and related products (Class L) – Part 1: General grouping\"; please share it with me, fellow enthusiasts. I’m not sure if this is the right place to post it; please forgive me if I’m wrong, moderators – move it to the appropriate section~~~~ This post was last edited by brant888888 on 2009-3-30 22:06.]
Introduction to the Classification of Lubricant Base Oils Date: 01-16-2006 09:29:12 Introduction to the Classification of Lubricant Base Oils In the past, major foreign oil companies classified base oils into paraffin-based base oils, intermediate-base oil, naphthenic-based base oils, etc., based on the properties of crude oil and the processing methods used. Since the 1980s, driven by the development of engine oils, lubricants have tended to be lower in viscosity, more multi-grade, and more universal in use, which has led to higher requirements for the viscosity index of base oils. The previous classification methods for base oils can no longer meet these changing trends. Therefore, major foreign oil companies currently generally classify based on the viscosity index, but there has been no strict standard to date. In 1993, API classified base oils into five categories (API-1509) and incorporated them into the EOLCS (API Engine Oil Certification System); the classification method is shown in Table-1. Table 1: Classification criteria for API-1509 base oils. Test methods: ASTM D2007, ASTM D2270, ASTM D2622/D4294/D4927/D3120. Category, Saturated hydrocarbon content/%, Viscosity index VI, Sulfur content/% (mass fraction). Class I: 90%, 80–120
