API 936 Refractory Personnel


API 936 Refractory Personnel – 4 days classroom training

The API 936 Refractory Personnel certification is designed to identify candidates possessing the knowledge of API STD 936 Refractory Installation Quality Control Guidelines. These are guidelines for the installation quality control of monolithic refractory linings and may be used to supplement owner specifications.

API 936 certification raises the bar of competence for qualified personnel, who must have knowledge of installation, inspection, testing and repair of refractory linings. It provides the industry with a prequalified set of individuals prepared for the job and readily identifies those who are qualified to do the job.

The course provides delegates with the following knowledge:

  • Quality Control
  • Physical Property Requirements
  • Inspection Documentation
  • Material Qualification Testing
  • Applicator Qualification Testing
  • Installation
  • As-installed Testing
  • Test Specimen Preparation
  • Test Procedures
  • Post Installation

This course is an excellent learning experience for people seeking knowledge in the installation, inspection, testing, and repair of monolithic refractory linings in demanding applications for pressure vessels, piping systems, fired equipment, and other refractory lined equipment.

Typically it is found that this course is suitable for the following individuals, but not limited to:

  • API inspectors and inspectors of statuary equipment
  • Asset Integrity Engineers
  • Regulatory inspectors involved in power plant and equipment inspection (with refractory)
  • Inspection Engineers of power boilers with refractory
  • Maintenance Technician/Engineers
  • Project Engineers
  • QA /QC Inspectors

So, whether or not you choose to take the exam, the information, knowledge and experience gained during the course will provide a fundamental element in the understanding of the refractory process, applications and specifications covered in all industries throughout the world from the petro-chemical industry to light industry.

Course Content

Delegates will be able to demonstrate knowledge in the following categories in preparation for the formal exam:

  • Laboratory Testing Procedures
  • Applicator and Material Qualification
  • Installation
  • Inspection
  • Post-Installation


The American Petroleum Institute (API) offers a certification program for individual in-service inspectors handling the in-service inspection of pressure vessels, pipework and storage tanks. API also manages an expansive catalog catalogue of API ‘codes’ which standardize practice. The certifications are a legal requirement for inspectors in many US states. However, the extension of US ownership to include international facilities and onshore plants, along with the lack of a similarly broad scope of recognized standards in other countries, has resulted in the widespread adoption of API practice within international plant industries. Many other countries regulatory authorities also use these codes to assess evidence of inspector competence. The API certification program is broken down into a series of API programs, programmes known as Individual Certification Programmes (ICPs).

Before applying for the API ICP exam candidates must ensure that they meet the minimum requirements defined by API. The table sets out the requirements for API 510/570/653;


EducationYears of Industry ExperienceExperience Required
BS or higher in engineering or technology1 yearSupervision or performance of inspection activities as described in API 510
2-year Associate’s degree or certificate in engineering or technology2 yearsDesign, fabrication, repair, operation, or inspection of pressure vessels, of which one year must be in supervision or performance of inspection activities as described in API 510
High school diploma or equivalent3 yearsDesign, fabrication, repair, operation, or inspection of pressure vessels, of which one year must be in supervision or performance of inspection activities as described in API 510
No formal education5 or more yearsDesign, fabrication, repair, operation, or inspection of pressure vessels, of which one year must be in supervision or performance of inspection activities as described in API 510

API certificates have become the most regarded, desired, and demanded credentials in the in-service inspection industry, providing a method to improve technical and code knowledge and strengthening the holder’s overall competence and career prospects.

The API examination is held within a Prometric Test Centre. There is a vast range of Prometric Test Centres located worldwide. Please visit the Prometric website to check available Prometric test centre locations near you.

The API exam application is completed online at the API website. You will be asked to provide evidence of previous relevant employment and experience. This experience will be verified by API who will contact the references you provide. At the time of completing your application, you will be asked to pay the relevant API registration fee. This varies depending on the exam you are registering for. Following API’s successful review and approval of your application, you will be provided with an exam eligibility ID number. You will need this number to book your exam with PROMETRIC. You will be provided with a link to PROMETRIC during your
API application. They have a range of locations throughout the world, with the UK sites located in Manchester, London, Glasgow, and Edinburgh. For information on further test center locations please visit the PROMETRIC website for further information.

The API exam application deadline is the date in which you must submit your application to API for review for the given exam cycle.

The API examination window is the period in which you can sit your exam. The examination window typically opens the day immediately after our classroom training; however, we do stagger some of our training dates to accommodate individuals who may be on different work rotations and unable to attend specific classroom dates.

Please contact our helpful team at Wilkinson Coutts for advice should your API application be rejected. Thankfully, rejection of exam applications are rare and so please do not worry about this process.
