(Main)Ductile iron pipes, fittings, accessories and their joints for sewerage applications - Guidelines for Pipelines Installation
Ductile iron pipes, fittings, accessories and their joints for sewerage applications - Guidelines for Pipelines Installation
This European Standard is a complementary document for the installation of ductile iron pipes, fittings, accessories and their joints, covered by EN 598:2009 harmonized standard. It is intended to describe, in a wider perspective, installation technologies, tools and pipelines particular examples, applicable for the construction, outside buildings, of:
- Drainage pipeline systems;
- Raw water pipeline systems;
- Sewage pipeline systems;
- Pipeline systems conveying surface water (e.g. rainwater), domestic waste water and/or certain types of industrial effluents, either in separate systems or in combined systems;
- Operating without pressure (gravity sewers) or with positive or negative pressure;
- Below or above ground installation types.
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. For this purpose, EN 12889:2000 applies

Cevi, fitingi, pribor in spoji iz duktilne železove litine za kanalizacijo - Smernice za vgradnjo cevovodov
Ta evropski standard je dopolnilni dokument za nameščanje cevi, fitingov, pribora in spojev iz duktilne železove litine, ki so zajeti v usklajeni standard EN 598:2009. Namenjen je širšemu opisu tehnologij nameščanja, orodja in določenih primerov cevovodov, ki se uporabljajo za gradnjo, zunanje stavbe:
– drenažni cevovodni sistemi;
– cevovodni sistemi za neobdelano vodo;
– komunalni cevovodni sistemi;
– cevovodni sistemi za odvod površinske vode (npr. padavinske vode), odpadne vode iz gospodinjstev in/ali določenih vrst industrijskih odplak, v ločene ali združene sisteme;
– delovanje brez tlaka (gravitacijska kanalizacija) ali z nadtlakom ali podtlakom;
– za podzemno ali nadzemno nameščanje.
Prav tako podaja nekaj navodil za upravljanje delovišča v zvezi z uporabo fitingov, ki so namenjeni za povezovanje odvodov in kanalizacije iz duktilne železove litine z drugimi materiali, kot so plastika, beton, keramika itd.
Ta evropski standard ne zajema:
– hidravlične zasnove sistemov odvodov odpadne vode in kanalizacije zunaj stavb. Za ta namen se uporablja standard EN 16933- 2.
– gradnje in preskušanja odvodov odpadne vode in kanalizacije na mestu samem. Za ta namen se uporablja standard EN 1610.
– Izvedbe in preskušanja odvodov odpadne vode in kanalizacije brez izkopa. Za ta namen se uporablja standard EN 12889:2000.
