The materials you may use are specified in the so called AD2000 W
pages. For example when you are building a pressure vessel with
unalloyed steel you must use AD2000-Merkblatt W1. If you look at
chapter 2 of this specification you can find all the materials
according to EN specifications you may use for such pressure vessels.
But it is not limited to the materials specified. Under 2.6 you can
see the requirements for materials not listed. If you want to use
other materials (meeting the requirements of 2.6) the notified body
need to give a single approval for the use. So it is possible to use
ASTM material but it's less complex when using materials listed in the
AD2000 Merkblatter. Beside the requirements for materials in W-pages
the materials and manufacturer also should met the requirements of
AD2000 Merkblatt W0 given in the chapters 2 and 3 of this W0
specification. This includes also that a manufacturer need to have a
quality assurance system (like ISO 9001) approved by a notified body
accepted by the PED 97/23/EG guidelines.
So in my opinion it is better to buy material from a AD2000 Merkblatt
approved manufacturer because in that case you are sure that all the
requirements are full filled (if the material ordered is within the
qualification range of the manufacturer). On the material certificates
3.1 according to EN 10204 the manufacturer has to specify that the
material met the requirements of the applicable AD2000 - W page as
well as for the European Pressure Equipment Directive 97/23/EG.
If this is the case than you don't have to worry about that.
