Work will be based upon EN15804.
The aim is to develop a single document per application when developing a LCA/EPD for plastic piping systems.
The Commission is recommending:Product Environment Footprint(PEF)
Whilst we have via TEPPFA EPD’s.
There is a need to understand the value/relationship of the 2 docs.

AHG 37 Policies relating to drinking water issues
Mandate M/136 (water intended for human consumption)
The Commission has agreed that TC 155 should be involved in the preparation of workprogrammes and the relevant candidate harmonized product standards, but onlywhen the detailed information on regulatory guidance governing product testrequirements 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 anydocument as further information is required.
We cannot prepare the response to the revision of M/136.
Work on-going!

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 thefire check sleevesmanufacturers are paying for the work.
We need to WATCH this work,
TEPPFA is involved.

Issues with:
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 TC165 and TC 155.
Whatever the outcome TC 155 needs more person power to work in both TC 165 and TC 164.

TC 155 is preparing aninventory 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.

Not sure when Mandate will be issued!
No liaison officer from TC 155 to M/366.
CE Marking: The Final Frontier!!
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.
GRP is included.
Industrial pipes and fittings are not required (CE not required for industrial products).
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!
He was clear that after July 1st2013 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/requirementscan be used.
Time scale:
Assuming that we can agree the model hEN for pressure then the other 3 hENs can be adapted accordingly.
We may need to change some of the standards/methods of test.
However, these would be moving requirements etc. into the hENs from the method of test or the product standard.
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 hENsARE 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!!
Future meetings:
CEN TC 155 Plenary –
Autumn 2013 20/21NovemberDenmark
Copenhagen -book early
Spring 2014 14/15 or 20/21 May Poland
Autumn 2014, week 47 or week 48 Croatia
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.
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.
Structure of ENs
For the Non-pressure ENs the following Part numbers indicate:
Part 1 The actual standard for pipes and fittings.
Part 2 Guide to the Assessment of conformity PUBLISHED AS A TS.
Part 3 Guide to installation practice and PUBLISHED AS A TS.
For the pressure ENs the following Part Numbers indicate:
Part 1 General requirements
Part 2Pipes
Part 3Fittings
Part 4Valves (if required)
Part 5Fitness for purpose
Part 6Installation practice WILL BE PUBLISHED AS A TS. (Except for GAS see EN 1555).
Part 7Guide 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 existingTRs/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.
