Friends, recently I attended one seminar on “Awareness training seminar on CE Marking – Pressure equipment directive” conducted by TUV India. I share below my learning:
Any std. adopted and published by CEN (European Committee for Standardization – Comite Europeen de normalisation) is known as EN std. (European standard). Incase it is published in “official Journal of the European Union”, it is known as “Harmonised Standard”. For example, PED 97/23/EC has been published in official Journal of Europa under no. L 181 on 09.07.1997.
All std. published in “official Journal of the European Union” can be seen at:
http://eur-lex.europa.eu/JOIndex.do?ihmlang=en
You can also search and download the harmonized std from above mentioned site.
“BLUE GUIDE” are also available for the interpretation of harmonized stds.
If anyone would like to place the product in the European Market, it is mandatory to provide “CE Marking” on it. And to have “CE Mark” one need to follow the appropriate regulation (like PED for Pressure Vessels) and the equipment has to be approved by “Notified Body” if applicable.
Hope the above information would be useful to all.

Just the below link for more information, interesting one
http://www.unm.fr/en/general/en13445/
published hormonised stanadrds for Directive 97/23/EEC can be seen at
http://ec.europa.eu/enterprise/newapproach/standardization/harmstds/refl
ist/equippre.html
and
http://www.newapproach.org/Directives/ProductFamilies.asp?97/23/EC
The attached list contains references to harmonised standards for
pressure equipment and harmonised supporting standards for materials
used in manufacturing pressure equipment.
The follwoing pretext taken from a CEN link may be helpful
A harmonised standards is a standard considered by the European
Commission as satisfying some of the directives essential safety
requirements.
Harmonised standards are covered by three types of European Standard:-
* Harmonised Product Standards
These are application codes that cover the design and manufacture
of Pressure Vessels, Boilers and Pipework
* Harmonised Support Standards
Welding, NDT and other standards that supplement the application
codes.
* Harmonised Material Standards
A material specified in a harmonised standard will satisfy the
requirements of the directive in terms of ductility, toughness and
strength but does not guarantee that the material will be suitable for
a specific application.
Each harmonised standard will contain an annex stating which essential
safety requirements it satisfies. The advantage of using these
standards is that no additional justification is required that essential
safety requirements have been met and providing the standards have been
correctly applied the design of the equipment can not be challenged.
Another advantage of using Harmonised Standards is that they provide an
interpretation of the directive. For example if a pressure vessel is
to operate below zero the impact tests on the material and welding
procedures have to be carried out the lowest operating temperature the
vessel will experience according to ESR 7.5. This is not current
practice as far as either PD5500 or ASME VIII is concerned as both
these standards permit, under certain circumstances, warmer impact test
temperatures.
Harmonised Standards are not essential, any appropriate standard can
used but the satisfaction of essential safety requirements must proved.
Both PD5500 and ASME VIII have produced annexes stating how and which
essential safety requirements they claim to satisfy, these annexes have
not been approved by the European commission and therefore neither
standard can claim to be harmonised.
Note PD5500 has nothing to do with the PED, it is simply the latest
revision of BS5500, it no longer has the status of a British Standard
because it will conflict with BSEN13445. It is now a Published
Document rather than a standard, This will make no difference to it as
it will continue to be supported as long as its popularity remains
The harmonised standard for the qualification of welding personnel is EN
ISO 9606, for operating procedures it is EN ISO 15614. (Note EN ISO
15614 only satisfies the requirements of E.S.R 3.1.2 it does not
satisfy the requirements for welding consumables stated in E.S.R 4)

Dear All,
I undrstand that Harmonised Standard For pressure vessel design for
PED is being published. BSEN13445. I have some querries.
- If this help us in selection of material.
- When this standard is likely to be published.
