All-Union State Standards 20799 – 88Industrial oils I-5А, I-8А, I-12А, I-12А1, I-20А, I-30А, I-40А, I-50А are refined distillate and residual oils or mixtures of them without any additives. These oils are utilized for machines and mechanisms of industrial equipment that does not impose specific requirements to anti-oxidation and anti-corrosion properties of oils. They can also be used as hydraulic liquids.Guarantee period of storage – 5 years from the day of manufacture.
