Frequently Asked Questions

The API-936 (Refractory Personnel) certification is designed to validate the knowledge and competence of professionals who work with refractory materials in the oil, gas, and petrochemical industries. This certification ensures that personnel understand proper installation, maintenance, and repair of refractory linings in equipment such as furnaces, reactors, and vessels.

The API-936 exam is intended for refractory workers, supervisors, engineers, and maintenance personnel involved in the installation, maintenance, and inspection of refractory materials in industrial facilities. It is particularly valuable for those working in the upstream, downstream, and midstream sectors of the oil and gas industry.

The exam covers refractory material properties, types of refractories, installation techniques, quality control procedures, safety practices, and inspection methods. It also includes knowledge of equipment design, thermal considerations, and industry standards related to refractory applications.

API offers training courses and study materials specifically designed for the API-936 certification. You can prepare by reviewing the API-936 standard document, attending official API training sessions, studying reference materials, and taking practice exams to familiarize yourself with the question format and content areas.

While specific passing scores may vary, API certification exams typically require a passing score of 70-75% to achieve certification. You should verify the current passing score requirement with API directly or through the exam registration materials, as standards may be updated periodically.
