What is another name for the 70 percent test conducted in fire apparatus testing?

The 70 percent test, commonly referred to as the 200 psi test, is a crucial part of fire apparatus testing that evaluates the pressure performance of the fire department's equipment. In this test, the system is subjected to pressures that are 200 psi for a specific duration, which allows for assessing the integrity and operational readiness of the apparatus under realistic conditions. This benchmark helps ensure that the equipment can handle operational demands safely and effectively during firefighting operations.

While the other terms have their significance in different contexts, they do not specifically align with the 70 percent test. A flow rate test typically measures how much water can be discharged in a given time, the pressure relief test assesses the functionality of pressure relief devices, and the safety pressure test may involve checks on the apparatus's overall safety features. However, none of these are equivalent to the 70 percent test, which is defined by its focus on testing under the set pressure of 200 psi, confirming that all components can sustain operational pressures without failure.
