  I want to test a weldment's tensile and impact characteristics which is of 4mm thick and does not conform to any of the ASTM standards... How do I test now? pls help me out...

  If a standard does not exist, then you can use the figures provided for the next smallest size. I dont get how ASTM standards come in here 👎

  Yeah.. Thankyou.. But is there any specific procedure to test nonstandard specimens without reducing their dimensions?

  Occasionally we had to deal with similar problems in failure analysis of objects. We designed fixtures to hold the specimen in the testing machine in such a way that the fixtures themselves do not introduce any unexpected twist or torque. Using the geometry of the specimen (essentially cross sectional area at different sections perpendicular to the applied stress) stresses at failure were calculated. The report specifies the special nature of the test. The other parameters like rate of traverse etc were maintained as in applicable standards.
