BRL 2023 version 2025 declared binding
A revised version of BRL 2023 for the Kiwa product certificate for "Structured-wall pipes made of PVC-U or PP intended for non-pressure sewerage inside buildings – Specific requirements" has been declared binding as of 17th of September 2025.
The following parts have been amended in the BRL:
- For the general requirements, reference is made to BRL 6300;
- Editorial changes based on the new KOMO template;
- The BRL has been rewritten to align as closely as possible with NEN-EN 13476-1 & -2 and NEN-EN 1453-1 regarding dimensions. Since there is no EN standard for the
PP 3-layer pipe for non-pressure sewerage inside buildings, the relevant requirements, where possible, have been included in this BRL.
The certificates issued on BRL 2023 version 2017 will lose their validity on 17-03-2026. The certificate holders will be informed about this transition period.
