As of March 12, 2026, API's current API 570 cycle uses the February 2026 Body of Knowledge and Publications Effectivity Sheet. The exam remains a 170-question in-person CBT with 110 closed-book questions, 60 open-book questions, and a 400-out-of-500 scaled passing score. API's current schedules-and-fees and policies pages list 2026 pricing at $875 for API members and $1,125 for nonmembers, and API does not publish public percentage-by-domain weights, so the percentages below are practice-weighted estimates aligned to the current BOK.
About the API 570 Exam
API 570 is API's in-service metallic piping inspection certification for owner-user mechanical-integrity programs in refining, petrochemical, and related process facilities. The exam tests inspection planning, damage-mechanism recognition, corrosion-rate and remaining-life calculations, piping component knowledge, welding and NDE fundamentals, repairs, alterations, rerating, and reference-driven code judgment using API 570, API RP 574, API RP 576, API RP 577, API RP 578, ASME B31.3, ASME Section V, ASME Section IX, and ASME PCC-2.

API 570 Exam Content Outline
Calculations, Intervals, and Integrity Evaluation
Corrosion rates, remaining life, thickness assessment, interval logic, flange and rating checks, flexibility and loading concerns, and the calculations or decisions used to keep piping fit for service.
Welding Procedure and Qualification Evaluation
WPS/PQR/WPQ distinctions, essential-variable control, filler-metal compatibility, preheat and PWHT execution, and practical welding-quality decisions tied to ASME Section IX and API RP 577 concepts.
Nondestructive Examination
Selecting and interpreting VT, PT, MT, RT, and UT; method strengths and limitations; basic Section V workflow; examiner qualification; and documenting coverage and acceptance basis.
Practical Knowledge - General
Inspection planning, owner-user responsibilities, circuitization, CML strategy, temporary repairs, rerating logic, documentation, and identifying high-risk locations from process conditions and service history.
Practical Knowledge - Specific
Piping components and joints from API RP 574, PRD system considerations from API RP 576, PMI controls from API RP 578, damage-mechanism recognition from API RP 571, and PCC-2 style repair-method judgment.

Frequently Asked Questions
How many questions are on the API 570 exam?
API states that the API 570 exam contains 170 multiple-choice questions, with 140 scored items and 30 pretest items. The exam is split into 110 closed-book questions followed by 60 open-book questions.
How long is the API 570 exam?
The official API 570 exam day is 7.5 hours long. API breaks that into a short tutorial, 2.75 hours for the closed-book portion, a 45-minute lunch break, and 3.75 hours for the open-book portion.
What score do I need to pass API 570?
API's current policies page states that all ICP exams use a 200 to 500 scaled-score model and that the passing scaled score is 400. Because the score is scaled, you should not treat it as a simple raw-percent cutoff.
What references are current for API 570 in 2026?
As of March 12, 2026, the current API 570 cycle uses the February 2026 Body of Knowledge and Publications Effectivity Sheet. Core references include API 570 5th Edition, API RP 574 5th Edition with Addendum 1, API RP 576 5th Edition, API RP 577 3rd Edition, API RP 578 4th Edition, ASME B31.3 2024, ASME B16.5 2020, ASME Section V 2023, ASME Section IX 2023, and ASME PCC-2 2022 in the sections listed on the official effectivity sheet.
Does API publish official domain percentages for API 570?
Not publicly. API publishes the official Body of Knowledge sections and the 110 closed-book / 60 open-book split, but it does not publish public percentage weights by domain. For study planning, use the BOK sections and the listed references; the percentages on this page are practice-weighted estimates aligned to the current BOK.
Is remote testing available for API 570 in 2026?
No. API's program-updates page says remote testing for core programs including API 570 was discontinued in September 2024, and the current API 570 exam page describes testing in Prometric computer testing centers.
What experience do I need to sit for API 570?
API uses education-and-experience pathways. Candidates with a BS or higher in engineering or technology, or 3+ years of military technical service, need 1 year of qualifying piping-inspection experience. Associate-degree or certificate pathways require 2 years, high school requires 3 years, and candidates with no formal education need 5 or more years, with at least 1 year involving supervision or performance of API 570-type inspection activities.
