Which of these is NOT commonly considered during the certification process?

During the certification process for a Diver Life Support System (DLSS), factors such as operational efficiency, system violations, and maintenance records hold significant importance. Operational efficiency pertains to how well the system performs and its ability to meet safety and performance standards. System violations refer to any deviations from the established norms or standards that could pose safety risks. Maintenance records provide crucial documentation that illustrates the care and integrity of the system over time, ensuring that it remains in optimal working condition.

Employee training levels, while important for overall safety and system operation, are generally not considered as a direct factor in the certification of the system itself. Instead, this aspect is part of organizational practices and protocols that ensure personnel are properly trained to operate and manage the DLSS. Therefore, while employee training is certainly vital for effective operation, it does not directly influence the certification of the system itself in the same way as the other factors mentioned.
