Mandate M/136 (water intended
for human consumption)
The Commission has agreed that
TC 155 should be involved in the
preparation of work programmes
and
the
relevant
candidate
harmonized product standards, but
only when the detailed information
on regulatory guidance governing
product test requirements has
been made available by the
Commission.
Although CEN/TC 155 took a
resolution during its last plenary
meeting stating that it is the
task of AHG 37 to prepare an
answer to mandate M/136 rev. 2, it
is too early to prepare any
document as further information is
required.
We cannot prepare the response
to the revision of M/136.

samples.
Reaction to fire and resistance
to fire.
At this stage we do not know who
will pay for the Test programme?
Brand names are included in the
reports of the products under test.
Therefore any manufacturer may
be named in a test report.
They are also changing the test
procedure/layout/installation
practice which may affect
Who will pay for all of the work?
Currently the fire check sleeves
manufacturers are paying for the
work.

TC155 Times
Water use and reuse rain water
and grey water and infiltration
system. Both system and product
approach.
There was a long discussion on the
relationship between TC 165 and
TC 155.
Whatever the outcome TC 155
needs more person power to work
in both TC 165 and TC 164.
CEN TC 249 WG 16
Thermoplastics welding
TC 155 is preparing an inventory of the
needs for standardization in welding,
butt fusion and electrofusion on PE
welding systems.
Mandate M/366 –
Dangerous Substances
TC 351(Construction Products:
Release of Dangerous substances)
has commenced work.
Mr Peereboom Liaison report from
CEN/TC 351/WG1.
Industrial pipes and fittings are not
required (CE not required for
industrial products).
Future meetings:
At this stage we should have a fair
idea of the total new CE marking
timetable. However, several CEN
members may still not support the
expected structure!
Autumn 2013 20/21 November
Denmark
He was clear that after July 1st
2013 when the CPR takes over
from the CPD, that CE marking
will become mandatory for those
products with a harmonised
standard that has been published
in the Official Journal.
Products without an approved
Harmonised Standard can still be
placed on the market.
It is clear that other marks can be
used alongside the CE Marking
including Quality Marks.
Meaning CE Marking, where
possible, must be called up by the
specifier/purchaser and other
Marks/requirements can be used.
Time scale:
Not sure when Mandate will be issued!
Assuming that we can agree the
model hEN for pressure then the
other 3 hENs can be adapted
accordingly.
No liaison officer from TC 155 to
M/366.
We may need to change some of
the standards/methods of test.
CE Marking: The Final
Frontier!!
However, these would be moving
requirements etc. into the hENs
from the method of test or the
product standard.
STILL NO REAL PROGRESS
the Commission has yet
to respond to TC 155
The “leaked” adverse letter
(document 3962) from the Dutch
Ministry is not the official position
of the Government. The goal of
high quality piping systems was
not challenged, only the possible
route of using the annex z
approach rather than the use of
“cluster hENs”.
hEN 15014 Pressure is being
rewritten in the style of the CEN
template and configured to
accommodate the product
standards. This document once
agreed will become the “model”
for the other hENs.
Thus we are looking at CE
introduction for our products circa
late 2015/mid 2016.
Until then we must keep our
customers informed about the
progress and the FACT THAT
OUR PIPES AND FITTINGS CAN
LEGITIMATLEY BE PLACED ON
THE MARKET WITHOUT CE
MARKING UNTIL OUR hENs ARE
HARMONISED AND PUBLISHED
IN THE OFFICIAL JOURNAL.
Note: Both Teppfa and PPG
have issued guidance papers.
Watch this space. CE was due
to be introduced in 1993!!
We are getting there!!
GRP is included.

NOTE.
This document is
prepared such that it gives an
overview of the workings of TC 155
in say 5/6 pages. Reference should
always be made to the full
documents and official minutes
/resolutions of the meeting.
It does not cover the work of
ISO138 Plastic Pipes and Fittings,
nor does it cover the work of other
CEN committees: CEN TC 164
water, CEN TC 165 drains and
sewers. To do this would require a
document of say 50 plus pages.
CEN Procedures
TC Doc
This indicates that the standard is
at a very early stage in its
development. It is still in the hands
of the WG or AHG and is not
sufficiently advanced to proceed to
the next stage.
prEN
This is the stage of the CEN inquiry
where the documents should be
available in three languages:
English, French and German.
The documents are sent out to all
CEN members and are subjected
to an enquiry. It is then up to the
Convenor to decide if the WG can
take into account the comments
made, and if so the revised
documents will be sent to the
formal vote.
5
TC155 Times
Formal Vote.
The documents are issued by CEN
for the Formal Vote, which is taken
on a weighted vote basis. Editorial
comments only allowed.
UAP
The document does not come out
for enquiry but goes straight to
Formal vote. Editorial and technical
comments allowed.
If the documents pass the Formal
Vote/UAP then the Member Bodies
are obliged to withdraw any
conflicting national standards within
6 months.
The term conflicting National standards is
very loose and only refers to standards
produced by the CEN member Body
Every EN can have a National
Foreword, which gives guidance
from the National viewpoint. These
are drafted at prEN stage.
TCA
Voting by correspondence –
applicable to TSs. NOTE: No
technical comments can be made
by correspondence.
Part 7 Guide to the Assessment
of
conformity
WILL
BE
PUBLISHED AS A TS.
TS Technical Specification
TC 155 originally decided to use
the ENV and then the TR for all
Assessment
of
Conformity
documents.
The decision has been taken to
now use the TS format and all
existing
TRs/ENVs
for
assessment of Conformity are
being converted into TSs.
The TS is a voluntary document
and as such the national codes
of practice or other National
standards/codes DO NOT have
to be withdrawn.
CEN TS are approved and
published in the same way as the
former ENV.
