No class A, B or C in this standard, only S or E.
It's about ultrasonic testing of flat steel product of thicknes 6 mm and above (reflection method)

And if there is any air pressure vessel in the machine the Single Presure Vessels Directive 87/404 or Presure equipment Directive 97/23/CE.

You must state in instructions the device is not intended for use in pressure vessels, otherwise the device may be consider a safety accesory under Directive 97/23/CE.

Perhaps, you are talking about non mandatory apendix ff "Guide for the design and operation of quickactuating closures.
A device should be present to avoid quick releive of pressure.

My vote is not too.
Never ever in Spain a vacuum vessel has been considered a pressure vessel.
Vacuum is considered in design and securities, but not in the legalizations.

Besides all what is previously said ,
Most european codes pre-PED (AD-Merkblatt, Codap, Racolta) usually stated Safety factors in test condition or excepcional conditions as S=1,1 (>< 10%)of yield strength or R0,02.
For austenitic steels, where R0,02 will apply, some parts of vessels (where a...
there is no need for spanish regulations if you do an EC Declaration of Conformity witn Mchinery Directive, so that in technical documentation you justify the gas type and burner characteristics.
If not you must comply with Royal Decree 919/2006 an its Technical Instruction ICG-08

Looks like you have read European Directive on Pressure Equipment.
In that contest, "equipment" includes vessels, pipes, pressure accessories ans safety accesories.

Cause standards are not law, are helping tools.
An ASME or API inspector for this countries is not authorized to certify to local regulations. They would prefer designs to local standards too and now to european norms EN.

Now it's clearer. As you told, that's the way PSV in steam boilers are tested.
Applying a force in the sharf to set pressure and knowing force, actual pressure and surface of seat valve you may calc set pressure.
But PSV for GLP usually are internal or external Rego type valves with no shaft...
Xianglu is right.
PED is law, not a standard.
European standards are EN.
Even leakage in the seat of the valve is allowed in some cases by PED.
You can access PED and guidelines at http://ec.europa.eu/enterprise/pressure_equipment/ped/index_en.html

May be you haven't seen a LPG tank hydrotested. I've seen hundreds instead. Most of them of less than 10 m3 in residential use.
All LPG tanks in spain are tested every ten or 12 years. Even big tanks in filling plants for road tanks are filled with water. Sometimes for thickness...
If question does not refer to ASME I'll give you my 2 cents.
PRV in LPG tanks are usually checked for set pressure during periodical hydrotest test of tanks.
This check is always done with water but procedure differs with operators.
You can test PRV on the tank fixing seat valve during hydrotest...
You mean that the Heater "was" supplied with CE mark and now it's replaced.
Is it a CE marked machine? Is it a gas burning equipment?
You may consider it new equipment if you are manufacturer.
If you don't, It will depent on local regulations, and requirements may vary in each country though...
