[MW:969] RE: 947] RE: 865] PED Harmonised Standard for Design

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.

 

Best regards,

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.
