EN 17176-2:2019/prA1

Plastics piping systems for water supply and for buried and above ground drainage, sewerage and irrigation under pressure - Oriented unplasticized poly(vinyl chloride) (PVC-O) - Part 2: Pipes

This part of FprEN 17176 specifies the characteristics of solid-wall pipes made of oriented unplasticized poly(vinyl chloride) (PVC-O) for piping systems intended for water supply and for buried drainage, sewerage, treated waste water and irrigation under pressure or above-ground where protected from direct sunlight. It also specifies the test parameters for the test methods referred to in this document.
In conjunction with FprEN 17176-1 and FprEN 17176-5, it is applicable to oriented PVC-O pipes with or without integral socket intended to be used for the following:
a)   water mains and services lines;
b)   conveyance of water for both outside and inside buildings;
c)   drainage, sewerage and treated waste water under pressure;
d)   irrigation under pressure.
It is applicable to piping systems intended for the supply of water with a maximum allowable operating pressure (PFA) up to and including 25 bar  . The piping system according to this document is intended for the conveyance of cold water up to and including 45 °C and especially in those applications where special performance requirements are needed, such as impact loads and pressure fluctuations.
For temperatures between 25 °C and 45 °C, Figure C.1 of this document applies.
This part of FprEN 17176 specifies a range of pipe sizes and pressure classes and gives a requirement and recommendations concerning colours.
NOTE   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.

European foreword
This document (EN 17176-2:2019/prA1:2021) has been prepared by Technical Committee CEN/TC 155
“Plastics piping systems and ducting systems”, the secretariat of which is held by NEN.
This document is currently submitted to the CEN Enquiry.
The main amendments to EN 17176-2:2019 are as follows:
— Correct MRS classification;
— Amend text nominal length (7.2) and tolerance Table 2;
— Revision Annex A Addition alternative interpretation reference lines (A.2.2 and A.2.3);
— Including clause test method in Annex E;
— Mistakes corrected in Table E and Annex E.
The amendment of EN 17176-2 is proposed to add clause E.5 Test report in Annex E,
to avoid miss interpretation and confusion in the market regarding reporting and use of the test results.
Also mistakes regarding MRS classification and ambiguities at different places, including Annex A, in the
document and mistakes identified in Table 8 and Annex E are amended. Table 2 Tolerance on length is
also amended to align with current practise.
1 Modifications to 5.4, "Orientation factor"
In Table 1, first row, replace MRS values "315 /355 /400 / 450 / 500" with "31,5 /35,5 /40,0 / 45,0 /
50,0" as follows:
"Table1 — Minimum orientation factor
Minimum required
31,5 35,5 40,0 45,0 50,0
strength (MRS)-MPa
Axial  1,0
Circumferential  1,5 1,6 1,7 1,8 1,9
".
2 Modifications to 7.2, "Length of pipes"
Replace the current text in 7.2 with the following:
"The nominal pipe length, l, shall be a minimum length which does not include the depth of the socketed
portions, as shown in Figure 1.
It is recommended to supply pipes in one or more of the following lengths: 3 m, 5 m, 6 m, 10 m or 12 m.
NOTE Other lengths are subject to agreement between the manufacturer and the purchaser.
The tolerance on the nominal pipe length is specified in Table 2.
Table 2 — Tolerance on nominal pipe length
Nominal pipe length Tolerance on length
≥ Manufacturer +0,05 m
declared value
Figure 1 — Points of measurement for nominal pipe lengths".
3 Modifications to 7.4, "Pipes with integral sockets with elastomeric sealing ring
type"
In the first paragraph, replace citation to "Figure 1" with "Figure 2".
In the title of Figure 1, replace “Figure 1 - Socket and spigot end for pipes with elastomeric sealing” with
“Figure 2 - Socket and spigot end for pipes with elastomeric sealing”.
4 Modifications to 9.1.1, "General"
In Table 5, replace headings "MRS315 /MRS355 /MRS400 / MRS450 / MRS500" with "MRS31,5 /MRS35,5 /MRS40,0 / MRS45,0 / MRS50,0" to read
as follows:
