H1 certified products carry the NSF mark

For lubricants to obtain H1 approval, their name, label, composition and safety data sheet of the product and all ingredients must be submitted to a certification body. A product inspection does not take place. The best-known certification body is the NSF (National Sanitation Foundation) in the US, which certifies products from around the world and from various fields. Products that have a confirmed H1 registration are marked with the NSF mark.

For the production of H1 lubricants, only raw materials listed in the "White Book ®" of the NSF or in accordance with certain paragraphs in the so-called Code of Federal Regulation (CFR) may be used. Further information on the raw materials used can be found here.

In addition to the official NSF certificate, all H1 lubricants from ELKALUB receive an additional signet.
