Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: API 580 Risk Based Inspection certification and API RP 580 / RP 581 body of knowledge (American Petroleum Institute); API RP 571: Damage Mechanisms Affecting Fixed Equipment in the Refining Industry (American Petroleum Institute). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Five skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: RBI Concepts and Planning (Purpose, Scope and Approaches); Probability of Failure and Damage Mechanisms (POF, Damage and Effectiveness); Consequence of Failure (Flammable, Toxic and Business); Risk Management and Inspection Planning (Risk matrix, Targets and Mitigation); Documentation, Reassessment and Roles (Records, MOC and Team). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

API 580 is the American Petroleum Institute's Risk Based Inspection certification. It tests knowledge of API RP 580, which sets out the elements of an RBI programme for fixed equipment and piping, along with related practices on damage mechanisms and quantitative RBI.

In RBI, risk is the combination of the probability (likelihood) of failure and the consequence of failure, where failure means loss of containment. Inspection effort is focused on equipment with the highest risk, and inspection mainly reduces uncertainty in the probability of failure.

No. It is an independent practice test written to the publicly available API 580 content outline for 2026 and 2027, for checking your readiness before you book the real exam. Passing earns a Science of Apps certificate rather than the official credential.
