The pressure recorded on the nameplate at the time of manufacture is known as the?

The pressure recorded on the nameplate at the time of manufacture is referred to as the factory test pressure. This pressure represents the maximum pressure at which the extinguisher was tested for safety before it is distributed for use. It ensures that the device can withstand pressure beyond its normal operating conditions and provides a measure of assurance regarding its integrity and reliability.

By indicating this pressure on the nameplate, manufacturers provide important information for both maintenance and inspection purposes, enabling users to understand the limits of the extinguisher's performance. The factory test pressure is critical for establishing a baseline for evaluating the condition of the extinguisher during routine checks and ensuring it is not subjected to potentially damaging pressures during use. Understanding this concept is vital for anyone involved in the selection, maintenance, or inspection of fire extinguishers.
