term compression strength of boxes). Document
being checked ahead of 2nd committee ballot.
Next meeting 14th April 2015.
WI 00155783 (Test method for determination of long
term structural compression strength of boxes).
Proposed test needs revision as the outcome of the
test results will not give distinctive results. UK
delegation working on revision to present to next
meeting.
WG20—Ancillaries for soil and waste discharge and
gravity buried drainage and sewerage systems
Convenor: Alastair Walmsley (UK)
WI 00155824 (Specification for boxes used for

Part 1 will also need to be revised to remove overlap.
TC 155 were asked about the timescale for this activity
and it was referred to WG20.

WG17—Rehabilitation of pipeline systems
WG 27 Environmental aspects
Convenor: Wim Elzink (NL).
Convenor:
Sándor Aranyi (Hungary). Drafts for
Environmental Product Declarations - Product
Category Rules for (i) buried pipes and (ii) pipes in
buildings to be sent to TC 155 for committee ballot
before CEN enquiry.
The scope of WG17 was recently aligned with ISO TC
138/SC8 (chaired by John Gumbel, UK) to include
trenchless replacement and renovation, SC8 lead on
standards development and includes both water and
gas applications. Wim Elzink is liaison officer between
TC 155 and ISO TC 138/SC8. Concern was raised at TC
155 over marginal difference between rehabilitation
(pipe in pipe) and no-dig installation of new pipes
(replacement by a new pipe) and where
responsibilities lie.
AHG 45 Lifetime expectancy of non-pressure piping
systems
Convenor: Henk Meerman (NL)
This AHG is working on a package of tests for
determining the life expectancy of materials of nonpressure pipes to increase options for use of recycled
materials. Two tests considered: Fatigue and Cracked
Round Bar method based on ISO/DIS 18489.
Comparative testing between two tests on PP and
PVC, virgin and non-virgin is ongoing to establish
method and equipment. Next meeting 2nd / 3rd
December 2014.
Next meeting - none planned.
WG25— Recycling of PVC-U, PE and PP materials
Convenor: Tinus De Lange (NL). Nothing to report.

5th member. Substances already listed for food
contact automatically to be accepted for water and
not included in core 4MS list. Test for mutual
recognition of Enhancement of Microbial Growth not

no driver to sort this. National Regulations continue.
CEN TC 127 Fire safety in buildings—draft EN 1366
includes plastic pipes, to be issued for CEN enquiry.

1433 (drainage channels) revision started but plastics
not well represented.
CEN / CLC TC 213 Underground plastics conduits for
protection of cables - new standard being drafted EN
50626 (part 1 for pulled cables, part 2 for other cable

consumption)
Spring 2015: Vienna, Austria
Four application-based harmonised standards (hENs) proceeding:

components buried in ground.
prEN 15014 Buried and above ground piping components for water
under pressure.
prEN 15015 Hot and cold water piping components.
The draft hENs were subject to a 5 month CEN enquiry following
which the tasks groups have started to discuss comments.
CEN TC 155 sought a meeting with the European Commission’s DG
Enterprise to confirm fundamentals of CE marking under the CPR,
clarify essential requirements and to identify a way forward.
DG Enterprise has proposed that CE marking for this sector may be
reviewed as products standards already exist to meet CPR objective
