How the API 570 exam questions developed? 

A question writing session is periodically conducted by Subject Matter Experts (SME’s), or individuals who specialize in pressure vessels, write questions from specific sections of the Code.  Each question is then checked by three other SME’s.

 

This validation exercise answers two questions;

  1. Is the question written clearly?
  2. Does the question cover knowledge that is important to a vessel inspector?

These questions then go into a question data-bank as non scored exam questions.

 

Presently there are over 1000 questions in the data-bank and are grouped by topics.  For each examination, there are 170 questions on the exam pulled from Area of Examination (see below). Only 140 Questions are scored. The remaining 30 are pre-test questions and not marked towards your score, that is, these pre-test questions do not affect your score whether you have answered them correctly or not. API does not tell you which ones these questions are.

API needs to ensure that these questions are not significantly challenged by the candidates and have also been answered by a reasonable number of candidates before adding them to their question bank as scored questions.

 

Publications Effectivity Sheet & Body of knowledge

Publications effectivity sheet is the list of applicable reference documents that you need to study for the exam. It also tells you which sections of each document are applicable. It can be revised from time to time when the codes and recommended practices or their addendum are revised and becomes applicable. Red texts indicate a revision or a change from the previous API Effectivity Sheet.

 

Body of knowledge also list the reference codes and recommended practices (without revision number) and elaborates on topics that a pressure vessel inspector needs to know giving examples. It shows what you are expected to know.

 

From time to time, API conducts a Job Analysis to re-evaluate the API 570 exam to ensure that it remains relevant and continues to focus on the inspectors’ core competencies. As a part of this process, the publication effectivity sheet and body of knowledge is revised. For example, API 570 Publications Effectivity Sheet applicable for exams held between June 2021 – October 2021 has been revised by adding the API RP 576 (Pressure Relieving Devices).

 

Number of Exam Questions per Code and RP

As per API Publication Effectively Sheet or reference material for API-570 exam, there are 4 ASME codes (ASME B31.3, ASME B16.5, ASME Code V & ASME Code IX), 4 Recommended Practices (571, 574, 576, 577, 578) and the all important API standard 570. However, all of them are not equally important and therefore, do not require equal emphasis.

 

About 40% of questions are asked from API 510 code which is some 80 pages long, while the rest contribute to remaining 60% which are 2000 pages long.

 

 

CodeApproximate Number of Questions
API 570 Code & API 57470 – 75
ASME Sec IX & API 57715 – 20
ASME Sec. V10 – 15
API RP 5718 – 10

No Negative Marking

The pass mark is roughly 70% for all the API examinations. No negative marking is applied. Therefore, make sure that you have answered all the questions. At the end, click the ‘’review all’’ button and peruse through the list to ensure that you have not skipped any question. You can also check ‘’review incomplete questions’’ to ensure there is nothing on the list, that is, no question left unanswered.
