Stichting Keuringsbureau Hout, the independent certification body of the Dutch timber industry, certifying products, processes and people and accredited by the Raad voor Accreditatie (C019). Its fire scope is narrow and specific: SKH is the body that certifies firms against BRL 0602, the assessment guideline for treating timber and timber products with fire-retardant agents under vacuum and pressure — which is what stands behind a claim that a piece of structural or cladding timber has been flame-retardant treated to a Dutch standard rather than simply coated. Its databank is one of the registers this directory’s Dutch supply-chain files were mined from.
