Rejectable Indication
An indication (detected defect) that exceeds acceptance criteria and must be repaired or the component rejected. Whether an indication is rejectable depends on material type, component function, applicable standard, and acceptance criteria. Standards like ASME Section V, AWS D1.1, and API standards define acceptance limits for various types of indications. Properly characterized and sized indications enable correct rejection/acceptance decisions.
