Which pressure is generally tested for hydraulic hoses?

Hydraulic hoses are primarily tested for hydrostatic test pressure, which is specifically designed to verify the integrity and strength of the hose material under high-pressure conditions. This test involves filling the hose with a fluid, typically water, and applying pressure that exceeds the maximum operating pressure to ensure that the hose can safely handle the required operational pressures without leaking or bursting.

Hydrostatic testing is critical because it simulates the conditions the hose will face in actual use while allowing for the detection of any weaknesses or flaws in the material that may not be visible under normal circumstances. It ensures that the hoses can perform safely under pressure, making it essential in applications where failure could lead to safety risks or operational downtime.

The other types of pressure - static, dynamic, and absolute - refer to different conditions and measurements but do not specifically address the testing protocols for hoses. Static pressure is related to the force exerted by a fluid at rest, dynamic pressure involves fluid in motion, and absolute pressure accounts for atmospheric pressure in addition to the measured pressure, but none of these directly reflect the testing protocols meant to validate the strength of hydraulic hoses.
