AD 2000 Merkblatt certification
AD 2000 Merkblatt certification
(OP)
I am working in a valve manufacturing company. We are manufacturing ball valves, Butterfly valves, actuators. I am working on a project about AD 2000 Merkblatt certification. what are certificates required for a valve manufacturer? we are procuring casting and forging from our foundry suppliers (who have AD 2000 merkblatt W0 certificates). which certificates we need to have?(in our name) for example AD 2000 Merkblatt A2, A4 etc., Thanks in advance.

*** Per ISO-4126, the generic term 'Safety Valve' is used regardless of application or design ***
*** 'Pressure-relief Valve' is the equivalent ASME/API term ***

PED only describes general safety requirements.-> You don't fabricate something according to the PED but to a code that full fills the requirements of the PED. This can be AD2000 or EN 12516 or even the ASME code( with additional testing) .
Part of the documentation you have to create for the valve is usually a declaration of conformity to the PED.
For AD2000 as the valve manufacturer you will need to be certified according to AD200 HP0.
Certification can be performed by a Notified Body (e.g. TÜV).
As to the requirements for the castings and forgings I replied to that in your other post here: https://www.eng-tips.com/viewthread.cfm?qid=483270
