Term for Motorcycles and Mopeds – Part 4: Mass of Vehicle with Two and Three Wheels
1 Subject Content and Application Scope
This standard specifies the technical requirements, packing, marking, storage and transportation, and sampling of general purpose lithium base grease for automobile.
This standard is applicable to the grease produced from the mineral lubricating oil that is thickened with fatty acid lithium soap and is added with antioxidant and rustinhibiting additives.
Products that comply with this standard are applicable to the lubrication of the frictional parts of automobile with working temperature between -30℃ and 120℃, such as hub bearing, chassis, water pump and generator. According to the principles stated in GB/T 7631.8, the designation is L-XCCHA2.
