Certification: KTW W270

Water is classified as drinking when it doesn’t contain any microorganism, parasites or other substances, in such a quantity to represent a potential danger to human health. The product materials in contact with drinking water can generate microbial growth and impurities/contaminants. This creates a serious health risk and a threat to the environment. Its organoleptic characteristics must be acceptable to the consumers, including clarity, transparency, the absence of colors and any anomalous odors.

The KTW & W270 certifications imply that product components in contact with drinking water have been tested and approved by German laboratories (TZW and DVGW) according to the recommendations of the UBA. This approval is one of the most restrictive in terms of lubricantscomposition.

Once granted, KTW and W270 approval lasts for five years.
