Is there a standard for Material Test Reports

[Mumawalde]

I was wondering if anyone knew of a standard or set of minimum requirements for a typical Material Test Report.

Here at work we generally see an ASTM or ASME number, a chemical analysis and a mechanical strength analysis.

Recently we received an MTR that had an ASTM number and a chemical analysis but no mechanical analysis. The supplier told us that they cannot get the material analysis for this specific material. Is the report still considered acceptable?

There seems to ne no any standard for test reports in ASTM/ASME. But in most of material specifications is referred to General specification which should be followed in addition to applicable material spec. And requirements for information to be stated on material test reports is described in these General spesification e.g. in SA-20 for SA-516 plates, SA-530 for SA-106-pipes etc.

But in General spec. is usually said like "When specified in the purchase order the supplier shall furnish a Certified Test Report certifying that the material was manufactured, sampled,tested, and inspected in accordance with the Specification.....

So if you do not require in your purchase order that Certified test report is required you maybe get test reports like you have now got

Dear Mumawalde,

I suggest you to take a look at EN10204 - Metallic products - Types of inspection documents.

Should you need a 3.1 certificate, the doc must reflect property of the material you are purchasing, therefore if reference ASTM indicates chemical analysis and mechanical properties, a 3.1 certificate must show those properties.

Same for 3.2 certificate, with the addition that a 3rd part should validate the document.

Should you need a 2.2 certificate, properties mentioned on the certificate should just "statistically" reflect the properties of the specific heat you are purchasing.

Anyway, in all 3 cases, properties mentioned on reference standard shall ALL be mentioned on the correspondent MTR, regardless they are just "statistical" or referring to the actual heat no. you are purchasing.

I hope I am not adding any confusion.

Some ASTM materials specifications do not require mechanical testing. You need to compare the MTR with the chemistry and test requirements of the ASTM spec.

what stanweld said. And if the ASME/ASTM spec for that material requires physical testing in addition to the chemical analysis, you have "non-compliant material". Fails to meet the spec, so send it back COD.

EN 10168 gives a menu of parameters that can be listed in inspection documents. It is incumbent upon the specifier to state exactly what is the required content of the inspection documents.
