This Technical Report contains the sanitary characteristics and test methods applicable to those factory applied lining, coating and jointing materials of ductile iron pipes and fittings conforming to EN 545 which are in contact with water intended for human consumption for use at operating temperatures up to 50 °C. Ductile cast iron itself is not in direct contact with the conveyed water therefore no characteristics in respect to the sanitary behaviour are necessary. As ductile cast iron is impermeable against diffusion of organic substances the water quality is maintained in service. Different surface/volume ratios are used in the tests for pipes, fittings and joints to reflect the different impact of their surface areas exposed to the water in the overall pipeline.

This European Standard specifies the requirements and associated test methods applicable to ductile iron fittings, ductile iron and mild steel couplings and flange adaptors and their joints to be used with poly(vinyl chloride) (PVC-U) pipes or polyethylene (PE) pipes. It is in conformity with EN 1452-1 to -5, ENV 1452-6 and -7 and EN 12201-1 to -5 respectively, for the construction of pipelines:
-   to convey water (e.g. water intended for human consumption);
-   with or without pressure;
-   to be installed below or above ground, inside or outside buildings.
This European Standard is not intended to cover sewerage applications, where additional requirements may be necessary.
This European Standard is applicable to fittings which are:
-   manufactured with socketed, flanged or spigot ends;
-   supplied externally and internally coated;
-   suitable for PE and PVC-U pipes with fluid temperatures between 0°C and 25°C, excluding frost, and for pressures up to 16 bar (PFA). For higher temperatures (up to 45°C for PVC-U or 40°C for PE) the PFA is derated as given in EN 1452 and EN 12201;
-   not intended for use in areas subjected to reaction to fire regulations.
NOTE 1   This does not preclude special arrangements for the products to be used at higher temperatures. Temperature limitations and pressure limitations are those coming from the PVC-U or PE pipes.
This European Standard covers ductile iron fittings, couplings and flange adaptors cast by any type of foundry process or manufactured by fabrication of cast components, as well as corresponding joints, in a size range extending from DN 60 to DN 700, to be used with pipes of external diameter from 63 mm to 710 mm.
As long as no equivalent European Standard exists for mild steel accessories, this European Standard also covers couplings and flange adaptors for use with PVC-U and PE pipes which are fabricated partly or entirely from mild steel as well as corresponding joints, in a size range extending from DN 60 to DN 700, to be used with pipes of external diameter from 63 mm to 710 mm.
This European Standard specifies requirements for materials, dimensions and tolerances, mechanical properties and standard coatings. It also gives minimum performance requirements for all components, including restrained and non-restrained flexible joints. Joint design and gasket shapes are outside the scope of this standard.
This European Standard does not cover fittings, couplings and flange adaptors intended to be used with different pipe materials other than PVC-U and PE.
NOTE 2    Fittings, couplings and flange adaptors complying with the requirements of this European Standard for PVC-U also usually meet the requirements for PVC-O and PVC-A pipes. Where this is not the case, the manufacturer is expected to declare this in the relevant literature.
NOTE 3   In this European Standard, all pressures are relative pressures, expressed in bars (100 kPa = 1 bar).

   to convey water (e. g. potable water);
   with or without pressure;
   to be installed below or above ground.
This standard is applicable to pipes, fittings and accessories which are:
   manufactured with socketed, flanged or spigot ends;
   normally delivered externally and internally coated;
   suitable for fluid temperatures between 0 °C and 50 °C, excluding frost.
This standard covers pipes, fittings and accessories cast by any type of foundry process or manufactured by fabrication of cast components, as well as corresponding joints, in a size range extending from DN 40 to DN 2 000, inclusive.
This standard specifies requirements for materials, dimensions and tolerances, mechanical properties and standard coatings of ductile iron pipes and fittings. It also gives performance requirements for all components including joints. Joint design and gasket shapes are outside the scope of this standard.
NOTE   In this standard, all pressures are relative pressures, expressed in bars (100 kPa = 1 bar).

This European Standard specifies the requirements and associated test methods applicable to ductile iron pipes,
fittings, accessories and their joints for the construction of drains and sewers outside buildings:
- operating without pressure (gravity sewerage), or with positive or negative pressure (see Table 5);
- to be installed below or above ground;
- to convey surface water, domestic waste water and certain types of industrial effluents, either in separate systems
or in combined systems.
This European Standard applies to pipes, fittings and accessories which are:
- manufactured with socketed, flanged or spigot ends;
- normally delivered externally and internally coated;
- suitable for continuous fluid temperatures between 0 °C excluding frost, and 45 °C for DN ≤ 200 or 35 °C for
DN > 200, according to EN 476;
- not intended for use in areas subject to reaction to fire regulations.
NOTE 1 This does not preclude special arrangements for the products to be used at higher temperatures.
This European Standard covers pipes, fittings and accessories cast by any type of foundry process or manufactured
by fabrication of cast components, as well as corresponding joints, of a size range extending from DN 80 to DN 2000
inclusive.
This European Standard specifies requirements for materials, dimensions and tolerances, mechanical properties and
standard coatings of ductile iron pipes and fittings. It also gives performance requirements for all components
including joints. Joint design and gasket shapes are outside the scope of this European Standard.

This European Standard specifies the requirements and associated test methods applicable to ductile iron pipes, fittings, accessories and their joints for theconstruction of pipelines: - to convey air or combustible gases (e.g. natural gas or town gas) at pressures up to 16 bar; - to be installed below or above ground. Note 1: A combustible gas is a gas or any fuel that is in a gaseous state at a temperature of 15°C at a pressure of 1 bar.

This European Standard defines the requirements and test methods applicable to factory applied extruded polyethylene coatings for the external corrosion protection of ductile iron pipes conforming to EN 545, EN 598 and EN 969 for use at operating temperatures up to 50 °C.
This European Standard does not cover ductile iron pipes protected with thin PE sleeve. Special works at site like drilling, tapping etc. may influence the corrosion protection properties. Those job steps shall be included in the instructions of pipe saddle and accessory manufacturers and all other essential installation instructions. These instructions are not part of this European Standard.
