Testing to verify that the application equipment and personnel are capable of meeting specified quality...

Applicator qualification testingis a term used in API 936 to describe the testing required to evaluate whether installation equipment and personnel can achieve the required physical properties (e.g., density, strength) in the final refractory. This testing often involves a mock-up or practice panel where variables like rebound, compaction, and finish are assessed.

The objective is to ensure:

Installation consistency across shifts or crews

Operator competence with specific materials

Adequate equipment settings (nozzles, air pressure, etc.)

Applicator qualification must be completed before production installation begins and is separate from material qualification or final as-installed testing.
