In order to obtain a GASTEC QA product certificate Kiwa uses two documents.
The GASTEC QA general requirements in which the procedure for obtaining and perpetuating of the certificate as well as the requirements for the certification body (Kiwa) are recorded. Next to this document Kiwa uses the GASTEC QA approval requirements in which the product requirements are specified.
Both documents together form the GASTEC QA certification scheme.
The GASTEC QA general requirements can be downloaded on this page. The GASTEC QA approval requirements can be downloaded through "QA keuringseisen".
