The API Refractory Personnel Exam: Practical Answers
The API-936 exam is the official assessment behind the API Refractory Personnel certification from API. In an age where technology skills need to be verifiable, a respected credential makes yours visible — it tells the market your abilities have been measured, not merely claimed. Earning it takes real preparation, and that preparation is exactly what our materials support.
Both. The API-936 test engine works offline once you have opened it online the first time — after that initial run, your connection is optional. The PDF edition goes further for paper learners: print all of the contents and annotate them into a personal workbook. Whichever of the three versions you prefer, the API Refractory Personnel content inside is the same daily-checked bank.
Plenty of them. Lead2Passed accepts a wide range of payment methods through a protected payment platform, so you can buy the API Refractory Personnel materials whichever way is most convenient for you. Every transaction is guarded at each step — convenience and security are both part of the checkout, not a trade-off between them.
Passing the API-936 exam requires Scaled score, approx. 70% correct (not publicly disclosed), and registration costs $450 (API members) / $625 (non-members). Focused preparation with verified answers is how you make that fee a one-time expense rather than a recurring one.
Registration for the API-936 exam runs through these official channels:
Pick a date that leaves room for steady practice — even a busy schedule can absorb short, regular sessions.
API recommends these training resources for candidates:
Official training builds the framework; daily-checked practice questions with verified answers build the finishing skill. Use them together.
The official outline divides the API-936 exam into weighted domains, including:
- Refractory Materials & Qualification (25%)
- Curing, Drying & Post-Installation (10%)
- Installation Methods & Procedures (20%)
The API Refractory Personnel bank at Lead2Passed is checked against these objectives every day, with new items added as the exam evolves.
The API-936 exam contains 85 (75 scored + 10 pretest) questions with 195 minutes minutes to complete them. Timed practice under the same limit — online or offline — turns pacing into a habit before exam day.
No mandatory prerequisites; relevant work experience recommended

Correct Answer:
Explanation:
mixing time
mix water levels
installation procedures
According to API Std 936 and supporting guidance from TR 980, cast sample mock-ups are used during pre-installation trials to ensure the suitability and repeatability of installation variables such as mixing procedures and water content. These mock-ups are critical to confirm that the material can be properly installed under anticipated field conditions.
From API 936:
"Mock-up cast sample trials shall be used to demonstrate the adequacy of the mixing time, water addition (mix water levels), and installation procedures prior to production installation."
- API Std 936, Section 6.3.2
This ensures that full-scale application performance is achievable using the approved methods and materials. However:
The "quality of the inspection equipment" and
"fabricator of the mock-up"
are not part of the qualification objectives defined for cast sample testing.

mixing time
