E500 mechanical test

501 round specimens should be prepared in accordance with recognized international standards.

502 If a fracture occurs in the weld or heat-affected zone, the test is considered unsuccessful and further testing is required.

The average of the minimum area shrinkage of at least three specimens is listed in Table E2. Only one specimen area shrinkage value is allowed to be less than the minimum average, but not less than the smallest single value of the corresponding steel grade shown.

When the area shrinkage value is less than the smallest single value, it should be rejected
