Safety of machinery. Lubricants with incidental product contact. Hygiene requirements has-tracked-changes The filtering efficiency can be1 Scope This International Standard specifies hygiene requirements for the formulation, manufacture, use and handling of lubricants which, during manufacture and processing, can come into incidental contact (e. g. through heat transfer, load transmission, lubrication or the corrosion protection of machinery) with products and packaging used in the food, food processing, cosmetics, pharmaceutical, tobacco or animal feeding stuffs industries.
