[MW:816] Re: Clarification requirements for NDT methods

 The product is hardwares,forged shafts, ( at raw material & after machined ). 

 

Can I put ASME SEC V at above stages ???

 

CCH 70-3 - Standard Specification for Inspection of steel casting for Hydrulic Machine.

Normaly this std applicable for hydulic turbines cast components such as runner balde,crown,band,guidevanes etc. That include inspection procedure & acceptance class.

What is your product? If your product specification refers you must use these standards, of course you can use always Section V in addition to these, but not instead of as these are product specific applications.

 

Like E165 for PT, A275 for MT and A388 for UT, no idea about CCH70
