3 Product variety and labeling
3.1 Product variety
The products covered by this standard include marine cylinder oils, marine system oils and marine medium-speed trunk-piston diesel engine oils, which are classified into different designations according to GB/T 14906 and base number grade:
Marine cylinder oils are classified into five designations: 5025, 5040, 5070, 5080 and 50100.
Marine system oils are classified into four designations: 3005, 3008, 4005 and 4008.
Marine medium-speed trunk-piston diesel engine oils are classified into 12 designations: 3012, 3015, 3020, 3030, 3040, 3050, 4012, 4015, 4020, 4030, 4040 and 4050.
For the designations above, the first two digits represent the viscosity grade and the latter digits represent the base number grade of the product.
