ISO 21469:2006 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. It is not applicable to substances used as product additives or to those in direct product contact, but confines itself to hygiene without addressing occupational health and safety matters.
