Who knows what else is wrong that you are not picking up. It was developed to assure delivery of steel plates free of gross internal discontinuities such as pipe, ruptures, or laminations and is to be used whenever the inquiry, contract, order, or specification states that the plates are to be subjected to ultrasonic examination.

At the proper sensitivity you may not even see them. Bottom line is that ASTM is a workmanship based criteria and when dealing with cracks you need to use an ECA based on fracture mechanics. Active view current version of standard.

I would print a copy of that to include in the final report packge that would be delivered to the customer. With a fracture already present the strength of the material is compromised and is not reliable a453 further analysis dependent upon astk intended use of the product.
