Which of the following is true regarding the pressure test duration specified by RV standards?

The correct answer highlights that the pressure test duration specified by RV standards must consistently be at least 3 minutes. This is important because a standardized duration ensures that the pressure testing process is thorough enough to identify potential leaks or weaknesses in the system being tested. By establishing a minimum duration, RV standards help maintain safety and reliability in RV components, such as water and gas systems, where leaks can pose significant risks.

The minimum duration of 3 minutes provides a baseline that technicians can rely on, ensuring that all units are subjected to a consistent level of testing. This consistency helps in maintaining overall quality assurance and allows for comparability across different RV units. It's essential for professionals in the industry to adhere to these guidelines to uphold safety standards and to ensure the integrity of the RV systems being evaluated.
