What is the test pressure for hose assemblies when not specified?

The test pressure for hose assemblies, when not specified, is established at three times the service pressure. This standard is set to ensure that the hoses can withstand significantly higher pressures than they are typically expected to handle during regular operation. By testing at this level, any potential weak points or vulnerabilities within the hose assembly can be identified before the assembly is placed into service, ensuring safety and reliability during actual use. This practice helps prevent failures that could occur if the hose were subjected to a pressure that's close to its limits, as the additional testing margin provides confidence that the assembly will perform effectively under pressure.
