Wheeled extinguishers with low pressure accessories are tested at which pressure?

Wheeled extinguishers with low-pressure accessories are typically tested at a pressure of 3000 psi. This testing standard is crucial for ensuring that the extinguishers can withstand the pressures associated with their operation without failing. The 3000 psi test pressure allows manufacturers to verify the integrity and safety of the extinguisher before it is placed into service. This pressure is in line with industry standards designed to ensure that the equipment can handle the expected operating conditions, which may include high-pressure scenarios in a fire situation. Testing at this level helps prevent possible leaks or failures that could lead to dangerous situations during use.
