Products and materials
in contact with drinking water


Clean drinking water ...
is a human right and an elementary component of life! 
 

  • The Drinking Water Ordinance (TrinkwV) regulates the quality of drinking water in Germany; Section 17 (3) contains requirements for materials/materials that come into contact with drinking water
  • Legally binding assessment principles are drawn up by the German Federal Environment Agency (UBA); they contain test programs and material-specific positive lists
  • In addition, there is the "Recommendation for Confirmation of Conformity", on the basis of which product manufacturers can have their product quality confirmed by an accredited certification body

As an accredited testing laboratory, we support you with quality control. Whether product testing, inspection or certification - our comprehensive services for products in contact with drinking water offer you and your customers the necessary safety when using your plastic products.
 

Also an issue at European level

In future, there will be harmonization in Europe for products in contact with drinking water.

On 23.04.2024, the European Commission published six 'Implemented' and 'Delegated Acts' in which the testing, monitoring and certification of products in contact with drinking water is regulated.

We would be happy to advise you on these and other topics relating to the testing of products and materials in contact with drinking water.

Testing

Confirmation of conformity of drinking water hygiene suitability

System 1+

  • Initial inspection of the factory and factory production control 
  • Monitoring of test specimen removal and type testing of the product 
  • Ongoing monitoring, assessment and evaluation of factory production control 
  • Random sample testing (audit-testing)
     

Type testing (for products Fc < 0,5 d/dm)

  • Test specimen removal for type testing of the product 
  • Type tests have a validity of 5 years
     

Type testing for primary products (e.g. plastic pellets)

  • Test specimen removal for type testing of the product
  • Type tests have a validity of 5 years
     

We can also provide support with self-monitoring (e.g. plastic pipes of category P1) and carry out tests, e.g. for total organic carbon.

Certification process

  • [1] Application for certification 
    Apply to an accredited certification body for all products / materials in contact with drinking water
  • [2] Formulation evaluation of the materials used 
    Verification of the material-specific composition of the products and comparison with approved positive lists of starting materials
  • [3] Initial inspection with sampling
    Initial inspection of the factory and evaluation of the factory production control as well as sampling of test specimens by a recognized inspection body
  • [4] Performance of the hygiene tests
    Confirmation of conformity on the basis of a type test. Checking the basic requirements, including requirements for the odor threshold value, turbidity and coloration and migration as well as the requirements regarding the promotion of microbial growth.
  • [5] Hygiene certification
    Issuance of a certificate that the requirements for hygienic suitability have been met.
  • [6] Annual monitoring with sampling 
    Assessment and verification of compliance with drinking water hygiene requirements during production

Testing

  • Composition (formulation)
  • Migration1
  • Microbiology
    (DIN EN 16421, DVGW W 270)
