About Kiwa Watermark for valves in metal piping
Kiwa Watermark quality mark certified valves for metal piping guarantee compliance with the requirements of Dutch and international standards for products used for drinking water distribution. In addition, the products meet the hygienic requirements, as set by the Dutch government. Only products that meet all requirements - including an agreed constant quality level - can be certified by Kiwa with the Kiwa Watermark.
Kiwa Watermark evaluation guidelines
The Kiwa Watermark evaluation guidelines include all requirements set by the market and government for products that come into contact with drinking water: both the private, functional requirements and the public, hygienic requirements.
Service taps (BRL-K611)
Kiwa Watermark certification under Kiwa evaluation guideline BRL K611 applies to service taps for water intended to be used as a shut-off device for underground supply pipes of tap water installations and can be used at a pressure of no more than 1000 kPa and a temperature of no more than 30°C.
The evaluation guideline BRL K611 is a certification scheme for the Kiwa product certificate for service taps.
Controllable backflow protection devices, family B, type A (BRL-K646)
Kiwa Watermark certification under Kiwa evaluation guideline BRL K646 applies to products intended to be used in drinking water installations with an operating pressure of at most 1MPa (10 bar) and a water temperature of at most 65°C.
The functional requirements for these products are based on EN 12729.
Together with necessary peripherals (upstream and downstream valves, sieve, 3 control taps) these products are used as backflow prevention units BA in tap water installations.
The evaluation guideline BRL K646 is a certification scheme for the Kiwa product certificate for controllable backflow protection devices, family B, type A.
Check valves for water in nominal sizes up to and including 1200 mm, class B (BRL-K651)
This BRL has been replaced by BRL K602.
Plastic service taps for water (BRL-K660)
Kiwa Watermark certification under Kiwa evaluation guideline BRL K660 applies to plastic service taps are intended for use in underground connections to pipes made of PE for drinking water. The pipes to be used must comply with NEN 7116. The recommended limits for correct operation are an operating pressure between 100 and 500 kPa and a water temperature of a maximum of 30ºC. The plastic service taps can be used for tap water applications with an operating pressure of up to 1000 kPa.
The evaluation guideline BRL K660 is a certification scheme for the Kiwa product certificate for plastic service taps for water.
Pressure reducing valves and combination valves (BRL-K14004)
Kiwa Watermark certification under Kiwa evaluation guideline BRL K14004 applies to pressure reducing valves and combination pressure reducing valves in nominal diameters from DN8 until DN100 are intended to be used in drinkingwater installations with a maximum water inlet pressure of 1600 kPa and a maximum water temperature of 30 ⁰C for cold water applications, resp. 80 °C for hot water applications.
The evaluation guideline BRL K14004 is a certification scheme for the Kiwa product certificate for water pressure reducing valves and combination water pressure reducing valves.
Technical Water Supply Protection for appliances with a contamination risk (BRL-K14011)
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.
Maintenance and testing of water meters (BRL-K14014)
Kiwa Watermark certification under Kiwa evaluation guideline BRL K14014 applies to
- maintenance and testing of water meters;
- carry out research on a metering installation as described in article 12 of VEWIN's Model General Conditions Drinking Water 2014;
- perform condition determinations and inspections in accordance with chapter 2 of the VEWIN Quality Assurance Regulations (RKW): dated 24 May 2018.
The evaluation guideline BRL K14014 is a certification scheme for the Kiwa process certificate for the maintenance and testing of water meters.
Tempering valves (BRL-K14024)
Kiwa Watermark certification under Kiwa evaluation guideline BRL K14024 applies to tempering valves intended to be used in drinking water installations, in nominal sizes from DN 15 to DN 50.
The evaluation guideline BRL K14024 is a certification scheme for the Kiwa product certificate for tempering valves.
Backflow protection devices Family A, type A,B,C,D,F (BRL-K14030)
Kiwa Watermark certification under Kiwa evaluation guideline BRL K14030 applies to mass-produced backflow protection devices belonging to Family A, in various types as included in NEN-EN 1717 and fitted with a downstream holding tank that is not intended for drinking water. The products are intended as a provision to prevent pollution of drinking water installations due to backflow. The products are intended for direct connection to drinking and/or hot water installations with a maximum working pressure of 1 MPa (10 bar) and a maximum temperature of 70°C.
The evaluation guideline BRL K14030 is a certification scheme for the Kiwa product certificate for backflow protection devices Family A, Type A, B, C, D, F and G in accordance with NEN-EN 1717, in combination with a holding tank not intended for drinking water.
Protection of dangerous devices
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.
