I have been asked to approve a materials cert for crane rails that states ASTM A759-10 high strength rails.
The cert supplied only lists chemistry and hardness.
As detailed in thread507-437086, whilst ASTM A759 only lists hardness, it does refer to ASTM-A1, which in turn refers to A29/A29M which then refers to A499 which lists the required mech properties (to be tested under A370) for various rails.
Our supplier says the product meets A759 because it has the correct hardness, but my reading of A759 is that some tensile should have been done.
Even the mill that supplied the material does not have any tensiles.
Note our spec requires ASTM A759 and specifically mentions that tensiles should be provided under ASTM A370
What am I going to do?
