Kiwa Watermark certification under Kiwa evaluation guideline BRL K14011 applies to ‘appliances with contamination risk’ manufactured in series and intended as receiving devices for connection to water installations. In accordance with NEN 1006, the drinking water and/ or hot water connection of these appliances with contamination risk must be fitted with a back flow protection. The nature of the backflow protection must be adapted to the degree of hazard of the device and the substances contained therein.

The backflow protection(s) shall prevent the drinking water and/ or hot water in the water installations from being contaminated as a result of possible backflow of substances from the appliances with a contamination risk and/ or the downstream connected appliances or installation(s).

The evaluation guideline BRL K14011 is a certification scheme for the Kiwa safety certificate for technical water protection for appliances with contamination risk.

The protection of so-called dangerous appliances is an important part of the protection of Dutch drinking water. Due to the nature of the liquids contained in them, these appliances can pose a risk to the drinking water in the installation to which they are connected.

Hazardous devices that occur are therefore assessed; the assessment is aimed at identifying the risk and prescribing appropriate security. When performing their statutory audit duties, drinking water companies then check whether the correct security is indeed in place.
