DIN EN 1796:2009 Plastics piping systems for water supply with or without pressure - Glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP) (includes Amendment A1:2009); English version of DIN EN 1796:2009-07
This European Standard specifies the required properties of the piping system and its components made from
glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP) intended to be used for
water supply (drinking or raw) with or without pressure. In a pipework system, pipes and fittings of different nominal
pressure and stiffness ratings may be used together.
NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into
account their particular requirements and any relevant national regulations and installation practices or codes.
This standard is applicable to GRP-UP, with flexible or rigid joints (see 3.37 and 3.38), primarily intended for use in
buried installations.
NOTE 2 Piping systems conforming to this standard can also be used for non-buried applications provided that the influence
of the environment and the supports are considered in the design of the pipes, fittings and joints.
It is applicable to pipes, fittings and their joints of nominal sizes from DN 100 to DN 3000, which are intended to be
used for the conveyance of water at temperatures up to 50 ~C, with or without pressure.
This standard covers a range of nominal sizes, nominal stiffnesses and nominal pressures.
Clause 4 specifies the general aspects of GRP-UP piping system intended to be used in the field of water supply
with or without pressure.
NOTE 3 Attention is drawn to the national requirements, in the country of installation, for the effects on water quality
applicable to pipes intended for use in possible contact with drinking water.
Clause 5 specifies the characteristics of pipes made from GRP-UP with or without aggregates and/or fillers. The
pipes can have a thermosetting or thermoplastics liner. Clause 5 also specifies the test parameters for the test
methods referred to in this standard.
Clause 6 specifies the characteristics of fittings made from GRP-UP with either a thermosetting or thermoplastics
liner intended to be used in the field of water supply. Clause 6 specifies the dimensional and performance
requirements for bends, branches, reducers, saddles and flanged adaptors and it also specifies the test parameters
for the test methods referred to in this standard.
Clause 6 is applicable to fittings made using any of the following techniques:
a) fabricated from straight pipe;
b) moulded by
1) filament winding;
2) tape winding;
3) contact moulding;
4) hot or cold press moulding.
Clause 7 is applicable to the joints to be used in GRP-UP piping systems to be used for the conveyance of water,
both buried and non-buried This specification is applicable to joints, which are or are not intended to be resistant to
axial loading. It covers requirements to prove the design of the joint. Clause 7 specifies type test performance
requirements for the following joints as a function of the declared nominal pressure rating of the pipeline or system:
a) socket-and-spigot or mechanical joint;
b) locked socket-and-spigot joint;
c) cemented or wrapped joint;
d) bolted flange joint.
