BS EN 599 allows the calculation of a performance factor or ‘critical value’ based on both lab and field test studies and the ‘CV’ is used to make recommendations for treatment to suit various end uses.

BS 8417:2003 recommends treatment based on CVs and desired service lives of 15, 30 and 60 years.
