Accreditations and conformity assessment bodies
In addition to the analysis of drinking water, the “Drinking water monitoring” department is also responsible for the analysis of bathing waters and the analysis of swimming pool and bathing pool water. The accreditation of testing laboratories is carried out in accordance with DIN EN ISO/IEC 17025, of inspection bodies in accordance with DIN EN ISO/IEC 17020 and of proficiency testing providers in accordance with DIN EN ISO/IEC 17043.
- Drinking water The requirements for ensuring drinking water quality are regulated by law in the German Drinking Water Ordinance (TrinkwV). Analysis of drinking water, including sampling, may only be carried out by approved testing laboratories. The essential prerequisite for approval is a valid accreditation for the analysis of drinking water pursuant to the Drinking Water Ordinance. The accreditation of inspection bodies in the area of drinking water, for example for the implementation of a hazard assessment in accordance with Section 16 TrinkwV (German Drinking Water Ordinance), is not required by the ordinance and has to date been the exception.
- Bathing waters: In terms of hygiene, the assessment of bathing waters is based on the European Directive on bathing water. There is no obligation to acquire accreditation in this area.
- Swimming pool and bathing pool water Microbiological, chemical and physico-chemical requirements for bathing pool water quality are defined in the DIN 19643:2012-11 series of standards , “Treatment of water of swimming pools and baths”.
Benefits of accreditation
The benefit of an accreditation for a conformity assessment body is that the results of its tests are trusted. Because the accreditation is accepted internationally, this produces a competitive advantage over non-accredited competitors.
