This draft amendment is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 155.

This draft amendment A1, if approved, will modify the European Standard EN 17176-2:2019. If this draft becomes an
amendment, CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for
inclusion of this amendment into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

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:
