BRL 5613 published for comments
The new draft-assessment directive BRL 5613 (KOMO) for “Plastic piping systems with metal inner layer intended for indoor heating installations: radiator connections” has been published for comments.
The plastics pipes with metal inner layer and fittings according to this new BRL 5613 are intended to be applied in piping systems inside buildings for hot water distribution with radiator connections at a design pressure (= maximum operating pressure) of 6 or 10 bar and in accordance with class 5 of ISO 10508.
BRL 5613 has been added to the existing KOMO BRL 56XX series for piping systems within this application (radiator connections and underfloor heating systems).

Evaluation guideline changes
An evaluation guideline or ‘Beoordelingsrichtlijn’ (BRL) is a package of requirements that a product or service can meet to demonstrate a certain guarantee of quality and legality. Kiwa offers BRLs in various subject areas. The requirements in a BRL are drawn up by an independent Board of Experts. A product or service is assessed by Kiwa on the basis of those requirements. When we introduce a new BRL or when a BRL changes, we will publish these BRL's.
