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

Tuyaux, raccords et accessoires en fonte ductile et leurs assemblages pour les applications en assainissement - Lignes directrices pour l’installation des canalisations
Le présent document est un document complémentaire pour l’installation de tuyaux, raccords et accessoires en fonte ductile et leurs assemblages, couverts par la norme harmonisée EN 598:2009. Il est destiné à décrire, dans une perspective plus large, des technologies d’installation, des exemples spécifiques d’outils et de canalisations, applicables à la construction, à l’extérieur des bâtiments, des éléments suivants :
— systèmes de canalisations de drainage ;
— systèmes de canalisations d’eaux brutes ;
— systèmes de canalisations d’eaux usées ;
— systèmes de canalisations de réutilisation des eaux usées, traitées ;
— systèmes de canalisations transportant des eaux de surface (par exemple, des eaux pluviales), des eaux usées domestiques et/ou certains types d’effluents industriels, en système séparatif ou en système unitaire ;
— fonctionnant sans pression (assainissement gravitaire) ou sous pression positive ou négative ;
— types d’installations dans le sol ou en élévation.
Il fournit également quelques instructions d’exploitation/de chantier pour l’application de raccords, destinés à être utilisés pour le raccordement des branchements et collecteurs d’assainissement en fonte ductile à d’autres matériaux tels que le plastique, le béton, le grès vernissé, etc.
Le présent document n’est pas destiné à couvrir :
— la conception hydraulique des systèmes de branchements et de collecteurs d’assainissement situés à l’extérieur de bâtiments. À cette fin, l’EN 16933 2 s’applique ;
— la construction et les essais sur site de branchements et collecteurs d’assainissement. À cette fin, l’EN 1610 s’applique ;
— la mise en œuvre sans tranchée et les essais des branchements et collecteurs d’assainissement. À cette fin, l’EN 12889 s’applique.
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.
