Final answer:
As-operated mode refers to testing under real-life conditions, while the CGSB-149-.10 test is conducted under controlled, ideal conditions.
Step-by-step explanation:
The difference between an as-operated mode and CGSB-149-.10 test lies in the testing conditions they refer to. The as-operated mode pertains to testing under real-life conditions, reflecting the actual operating environment and scenarios of the equipment or system in question. On the other hand, the CGSB-149-.10 test refers to a standardized method of testing under controlled, ideal conditions, often set forth in regulatory or technical standards to ensure consistency and repeatability of the test outcomes.
Therefore, the correct option to identify the difference is: A) As-operated: Real-life conditions, CGSB-149-.10: Ideal conditions.
