MTR Certification Requirements MTR Certification Requirements rustbuster (Petroleum) (OP) 5 Apr 12 14:37 I have recieved some suspect 304H pipe from an Asian mill. The MTR's are not signed or stamped.Is this a requirement? I don't recall ever seeing MTR's without a signature. RE: MTR Certification Requirements SnTMan (Mechanical) 5 Apr 12 17:11 Well I can certify to all kinds of things if I don't have to sign it:)Regards,Mike RE: MTR Certification Requirements metengr (Materials) 5 Apr 12 19:49 Quote:Is this a requirement? I don't recall ever seeing MTR's without a signature No, there is no requirement.Review ASME SA 530, specifically under 21.1 Certified Test ReportWhen specified in the PO or contract the producer or supplier shall furnish a Certified Test Report certifying that the material was manufacured, sampled, tested and inspected in accordance with the Specification, including..... A signature or noterization is not required on the Certified Test Report..... RE: MTR Certification Requirements gtaw (Structural) 7 Apr 12 00:15 You received material from Asia that doesn't meet spec.? That surprises you?I have a bridge in NYC that I want to sell. Boy, have I got a deal for you! Best regards - Al RE: MTR Certification Requirements EdStainless (Materials) 11 Apr 12 08:59 If an MTR has no name, seal, or stamp it is just raw data. a certified test report must include the authority that prepared it. This can be per-printed or stamped or anything else.I think that this is the least of your worries.Do a chem and a micro to check grain size for starters. You might also take some dimensions and see if it is the correct size. = = = = = = = = = = = = = = = = = = = = Plymouth Tube RE: MTR Certification Requirements metengr (Materials) 11 Apr 12 09:12 Send it back to the supplier. I personally would not bother to do anything with the suspect material. Why take on the risk? Also, you will have serious traceability issues.
