The European standard EN 877 is valid for prefabricated parts of iron pipes for construction – normally as non-pressure pipelines – of building drainage systems as well as connecting drains. The nominal diameter range covers DN40 – to DN600 inclusive. Ducker drainage pipe systems are manufactured of grey cast iron GG according to EN 1561 – type at least EN-GJL-150 (formerly GG 15 according to DIN 1691).
Ducker SML drainage pipe systems are in accordance with this standart and exceed its requirements by far in many respects. Also the demands of DIN 19522 and ISO 6594 are passed.
