H1 lubricant
H1 lubricants are lubricants for machines and systems in the food and feed industry. Such food-grade lubricants ( lubricating oils or greases ) can be equivalent or superior to conventional lubricants in terms of water resistance, low-temperature properties, longevity and stability against environmental influences.
The US Food and Drug Administration (FDA) has drawn up a positive list of base oils and additives that may occasionally come into direct contact with food in low concentrations. The US organization NSF International (formerly known as the National Sanitation Foundation) tests whether lubricants are food-safe. Lubricants that occasionally come into direct contact with food may be given the H1 release status; these meet the requirements of FDA rule 21 CFR 178.3570. Where there is occasional - technically unavoidable - contact with food, only lubricants of class NSF H1 may be used in the USA.
In Europe there are similar requirements for the food tolerance of lubricants that - even occasionally - come into direct contact with food. In regulations such as the International Featured Standard , the use of such lubricants is explicitly required and this is regularly checked in audits .
