Mr Peereboom Liaison report from CEN/TC 351/WG1
CE Marking: The Final Frontier!!
This topic was, for the first time, right at the start of the meeting after the normal routine reports.
With the Consultant, Mr Bedotti, Mr Amilcar Da Costa and Goncalo Asensao present it was possible to have a well-informed debate.
The concept of Cluster hENS with supporting product standards and methods of tests is now accepted.
hEN 15014 Pressure is being rewritten and configured to accommodate the product standards. This document once agreed will become the “model” for the other hEN’s.
This process should be completed end of February.
There will be a meeting in February 2013 with the CEN Consultant.
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!
For the first time I found that Mr Bedotti was accepting the “Cluster hEN’s” along with the products standards.
He was clear that after July 1st 2013 when the CPR takes over from the CPD that CE marking will become mandatory for these 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.
He was clear that other marks can be used alongside the CE Marking including Quality Marks.
The Customer can he said “specify the name of the driver of the truck if he wants to”!!!
Meaning CE marking, where possible, must be called up by the specifier / purchaser and other Marks / requirements can be used
Time scale:
Assuming that we can agree the model hEN for pressure then the other 3 hEN’s 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.
Given that the nature of the work is editorial then it is possible that the whole task is completed in 30 to 36 months.
Thus we are looking at CE circa 2015.
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.
Watch this space. CE was due to be introduced in 1993!!
We are getting there!!
Future meetings
CEN TC 155 Plenary –
Bulgaria - Sofia 15th and 16th May 2013.
Autumn: 20th and 21st Nov 2013. No location.
Spring: 14th and 15th May or 20th and 21st May 2014.
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 TS’s.
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 2 Pipes
Part 3 Fittings
Part 4 Valves (if required)
Part 5 Fitness for purpose
Part 6 Installation practice WILL BE PUBLISHED AS A TS. (Except for GAS see EN 1555).
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 TS’s.
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.
This was the last meeting of TC 155 chaired by Karl Johan Strom after chairing some 35 Plenary meetings and many ad-hoc / organised meetings with other TC Chairs, The Commission and CEN.
Karl played a major role in developing our range of standards that form the bedrock of our industry. We wish him well in the future.
Herman Renier is the new chairman of TC 155. We wish him every success in this key role for our industry. He will be our “leader” as we introduce CE marking and many of the environmental requirements for the future.
