Advice on PMA design codes for materials?
Advice on PMA design codes for materials?
(OP)
Hi All,
Im after a bit of advice if anyone can help - thanks!
I am writing a number of PMAs. In terms of the PED, a design criteria needs to be specified (eg. ASME BPVC Section II Part D). If the material I am using is not covered in this, how do I specify the design criteria? I am using a number of ASTM and BS standards (BS standards that are not harmonised so require a PMA) that this applies to.

My had is spinning already! About 30 PMA`s was signed by NoBo. But few of then came back with the comment "not include in ASME II part D." Which is true but I explained on the PMA those materials are in the same group (as per ASME B 16.34) with the others which include in the ASME II part D we use the calc. as per Mandatory Appendix 1 (Table 1-100).
Yield and Tensile stress data are from the Material standards.
Not acceptable. :(
Si, I have no idea what can be the Design criteria.
Thanks again
