material producer, and fulfils the requirements of Table 3 and 5 of this document for PE 100-RC. A co-
extruded pipe made of a combination of PE 100 and PE 100-RC layers shall be regarded as PE 100 and
marked accordingly.
5.2 Compound for identification stripes
The stripe compound (see 6.2) shall be manufactured from a PE base polymer in accordance with
EN 12201-1, which is used for a pipe compound for which fusion compatibility has been proven. Fusion
compatibility is not applicable for PE 40 materials.
The compound used for identification stripes in form of a pipe shall conform to the following test
requirements of resistance to weathering as described in EN 12201-1:2024, Table 2:
— Decohesion test requirement for PE 80, PE 100 and PE 100-RC stripe compound;
— Hydrostatic strength test (1 000 h at 80 °C and 2,0 MPa) and the elongation at break test
requirements for PE 40 stripe compound (to be performed on pipe d : 32 mm SDR 11).
n
The OIT of the stripe compound shall be ≥ 10 min at 210 °C, measured by the compound supplier in
accordance with EN ISO 11357-6 (table footnote d of Table 5 applies).
5.3 External reworked material and recyclate
Reworked material obtained from external sources and recyclate (pre-consumer and post-consumer
material) shall not be used.
6 General characteristics
6.1 Appearance
When viewed without magnification the internal and external surfaces of pipes shall be smooth and clean
and shall have no scoring, cavities, and other surface defects to an extent that would prevent conformity
to this document.
The ends of the pipe shall be cut cleanly and square to the axis of the pipe.
6.2 Colour
Pipes intended for the conveyance of water for human consumption shall be black or blue. In addition,
black pipes may be identified by blue stripes, according to national preference. Blue pipes or black pipes
with blue stripes are intended for the conveyance of water for human consumption only.
Pipes intended for vacuum sewer system, drains and sewers shall be black or black with brown stripes
or according to national preference.
The outer co-extruded layer of co-extruded pipes (see Annex B) or the outer peelable layer of peelable
layer pipes (see Annex C) for pipe intended for the conveyance of water for human consumption shall be
either black, blue or black with blue stripes. In addition, identification stripes may be used according to
national preference for the application.
The outer co-extruded layer of co-extruded pipes (see Annex B) or the outer peelable layer of peelable
layer pipes (see Annex C) for pipe intended for drains and sewers under pressure, vacuum sewer systems,
and water for other purposes shall be either black or black with brown stripes or brown, or according to
national preference. In addition, identification stripes of a different colour may be used according to
national preference for the application.
National preference for colour can be stated in the National Foreword.
For above ground applications, all components other than black are unsuitable for service in direct UV
light without a protective layer.
6.3 Effect on water quality
For compounds intended to be used for components in contact with water for human consumption,
attention is drawn to the requirements of national regulations.
7 Geometrical characteristics
7.1 Measurement of dimensions
The dimensions of the pipe shall be measured in accordance with EN ISO 3126 and rounded to the next
0,1 mm. In case of dispute, the measurement shall not be made less than 24 h after manufacture and after
being conditioned for at least 4 h at (23 ± 2) °C.
Indirect measurement at the stage of production is allowed at shorter time periods provided that
evidence is shown of correlation.
The national preference for pipe size and PN rating can be given in the National Foreword.
7.2 Mean outside diameters, out-of-roundness (ovality) and tolerances
The mean outside diameters of the pipe, d , shall conform to with Table 1.
em
NOTE The nominal outside diameters, dn, given in Table 1 are selected from ISO 161-1 [7].
For straight pipes, the maximum out-of-roundness shall conform to Table 1. For coiled pipes, the
maximum out-of-roundness shall be specified by agreement between the manufacturer and the end user.
Care should be taken that packaging and storage does not lead to an increased out of roundness and
flattening of the pipe.
Pipe extruded from PE 40 materials shall be limited to diameters up to and including 63 mm. However,
in some countries pipe made from PE 40 materials may be used in diameters up to and including 90 mm.
If this is the case this should be stated in the National Foreword.
