Please note: Transition period BRL-K14010 part 1
The BRL-K14010 part 1 series is currently still in the transition phase. This means that not all certificates have been converted to the new versions yet.
What does this mean for you?
Certificates issued on the basis of the ’old’ BRL remain valid as long as they can be found via the certificate search tool on our website (Certified companies and organizations). You can therefore rely on the validity of these certificates as long as they are visible there.
We are doing everything we can to complete the conversion process as soon as possible and will keep you informed of the progress.
About the assessment directive
The assessment directive focuses on physical techniques applied in collective drinking water and domestic hot water installations. The equipment can be introduced at two levels:
- At the central supply of the (partial) installation (point of entry)
- Directly before the tap point (point of use).
Here, BRL-K14010 part 1a focuses specifically on the point of entry techniques, while BRL-K14010 part 1b applies to the point of use techniques. This concerns the following techniques: microfiltration and ultrafiltration, pasteurization and UV treatment with low-pressure lamps. This BRL is important for, among others, owners of collective tap water installations.
The Kiwa Water Mark may be carried by certificate holders for and on products that come into contact with drinking water and meet all requirements from the relevant Kiwa assessment directives. These assessment directives contain all the requirements set by the market and the government for products that come into contact with drinking water: both the private, functional requirements and the public, hygienic requirements.
The Kiwa Water Mark is therefore the most efficient tool for selling and using these products on the Dutch market: producers and suppliers only have to deal with one set of requirements and the user is completely unburdened and does not have to look any further.
The process steps for obtaining the certificate with Kiwa Water Mark:

Electrochemical techniques for legionella prevention (BRL-K14010 part 2)
There are various techniques to prevent or reduce the growth of legionella bacteria in tap water installations. Under certain conditions, electrochemical techniques may be used for this purpose. In consultation with the government and the market, Kiwa has developed the assessment directive (Dutch: beoordelingsrichtlijn (BRL)) ’Legionella prevention with alternative techniques, part 2: Electrochemical techniques’ (BRL-K14010-2).
Chemical techniques for legionella prevention (BRL-K14010 part 3)
There are various techniques to prevent or reduce the growth of legionella bacteria in tap water installations. Under certain conditions, electrochemical techniques may be used for this purpose. In consultation with the government and the market, Kiwa has developed the assessment directive (Dutch: beoordelingsrichtlijn (BRL)) ’Legionella prevention with alternative techniques, part 3: Chemical techniques’ (BRL-K14010 part 3).
