Such issues are the result of project complexity, size, uniqueness and regulation, as well as the need for virtual team collaboration. I appreciate your assistance! A is not only applicable to alloy clad plate but can also be applied to “normal” plate. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
I am currently translating the document into Japanese so that my coworkers know which procedures to follow, and am unclear on ast, few particulars of the acceptance standards sections 7, 8 and 9.

The test shall be performed either by direct contact, immersion, or liquid column coupling.
A is for steel plate and A is for alloy clad steel plate. Promoting, selling, recruiting, coursework and thesis posting is forbidden. If I’m understanding correctly that the circle diameter is to be no smaller than 3 inches regardless of the thickness of the plate, this test seems very easy to pass as you would need quite a large indication to be outside the bounds of the circle.
