It also gives some site operation/site instructions for the application of fittings, intended to be used for the connection of ductile iron drains and sewers to other materials as plastic, concrete, vitrified clay, etc. This European Standard is not intended to cover: - Hydraulic design of drains and sewers systems outside buildings. For this purpose, EN 16933-2 applies. - Construction and site testing of drains and sewers. For this purpose, EN 1610 applies. - Trenchless construction and testing of drains and sewers.
