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.
