In L-HM-32, the L stands for lubricating oil, HM stands for anti-wear hydraulic fluid, and 32 represents the viscosity. L-TSA46 L denotes lubricating oil; T stands for turbine (steam engine); S refers to the addition of an anti-rust solvent; A means antioxidant property; 46 indicates the viscosity.
Take a look at this for better understanding: GBT 7631.1-2008 Classification of lubricants, industrial oils and related products (Class L) – Part 1: General grouping http://www.hgsanji.com/viewthread.php?tid=898&page=1&extra=#pid1004
