Important notes:

  • The existence of a relevant EN standard does not necessarily mean that all supplies of a chemical will have been tested to and shown to meet the appropriate requirements of the EN standard. These standards contain requirements for impurities and may additionally have a national condition of use assigned to them. Please check these conditions in the respective country of the EU.
  • Since EN standards for drinking water treatment do not contain mandatory requirements for attestation of conformity, it is the responsibility of the user of these chemicals to ensure that these chemicals provided by a specific supplier fully meet the test requirements of the relevant EN standard by provision of a certificate of attestation for the supplied chemical batch.
  • It is recommended that end users of treatment chemicals or materials that have an EN standard associated to them have access to the current version to ensure that the product supplied conforms.
