While the original ASME CC 2235 was not clear on this issue, the intent was to use artificial cracks - not side drilled holes or notches - as the reflectors. In addition, the artificial cracks should follow the bevel to simulate Lack of Fusion defects or similar. ASME is currently working on clarifying this situation.
