To allow ductile iron pipe manufacturers and users of the product to apply TMPO linings and thereby comply with the relevant requirements of EN 545, EN 545, EN 969. This demonstrates innovation according to Annex I, by the use of non-traditional coating systems offering environmental and economic benefits. The TMPO linings meet the criteria expressed in EN 14901, except for those pertinent to fusion bonded epoxy chemistry. The linings are being used in other parts of the world eg Australia and New Zealand and have been incorporated in the recent AWWA C116/A21.16-15 publication. The current status for TMPO linings in EU amounts to a barrier to trade and does not support SME’s involved in the manufacture, lining and application of the material that offers human health benefits, as highlighted in the Annex I and II.

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 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.

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).

This European Standard specifies the technical delivery conditions for bends made by the induction bending process for use in pipeline transportation systems for the petroleum and natural gas industries as defined in ISO 13623.
This European Standard is applicable to induction bends made from seamless and welded pipe of unalloyed or low-alloy steels.
NOTE   These are typically C-Mn steels or low-alloy steels that are appropriate for the corresponding level and grade of line pipe in accordance with ISO 3183.
This European Standard specifies the requirements for the manufacture of two product specification levels (PSLs) of induction bend corresponding to product specification levels given for pipe in ISO 3183.
This European Standard is not applicable to the selection of the induction bend product specification level. It is the responsibility of the purchaser to specify the PSL, based upon the intended use and design requirements; see also ISO 3183:2007, Introduction.
This European Standard is not applicable to pipeline bends made by other manufacturing processes.
On-land supply systems used by the gas supply industry excluding gas infrastructure from the input of gas into the on-shore transmission network up to the inlet connection of gas appliances "are excluded from the scope of this standard.
