The API-SIRE Source Inspector Rotating Equipment certification is a valuable credential for professionals involved in quality assurance and inspection within the oil, petrochemical, and gas industries. It validates the expertise required to oversee manufacturing processes and ensure that rotating equipment meets strict industry standards before it reaches operational sites.

The API-SIRE exam is designed to assess the competency of source inspectors who perform quality surveillance at supplier or vendor facilities. These inspectors represent purchasers and are responsible for verifying that equipment is manufactured according to specifications, codes, and contractual requirements.
Their role is critical in preventing defects, reducing operational risks, and ensuring long-term equipment reliability.
Source inspectors certified under API-SIRE are expected to:
Inspect equipment and materials during fabrication at vendor sites Monitor manufacturing and assembly processes Verify compliance with quality management systems Identify non-conformities and ensure corrective actions are taken Witness testing and validate results
Their work directly impacts the safety and efficiency of operations in high-risk industries.
Understanding the structure of the exam is essential for proper preparation:
Duration: 3.25 hours
Total Questions: 110 multiple-choice questions
Scored Questions: 100
Unscored (Pretest): 10 questions
Exam Type: Closed-book (no reference materials allowed)
Candidates must rely on their knowledge and practical experience to complete the exam within the time limit.
