1. It must be linear indication
2. The indication level must be above reference level
3. Comply with Rejectable length.

First of all, where does it state in ASME B31.3 that an indication has to be linear to be rejected?

If you have Lack of Fusion or a crack or Lack of Penetration, it is rejected anyway, regardless of length. If you don’t reject it, you’re not doing your job.
