Annual Hydrostatic Test to be conducted by purchaser on all in-service (used) hose to determine suitability for continue use. The service test pressure is to be 10% greater than the "normal highest operating pressure" at which the hose is expected to be used. (See Operating/Working Pressure below).

Note: This is the pressure stenciled on the hose. 

 

The "one-time" test pressure, performed by the factory, on every new hose prior to shipping. The proof test pressure shall not be less than two times the specified service test pressure.

 

The minimum burst test pressure, performed by the factory, shall not be less than three times the specified service test pressure.

 

Maximum advised operating/working pressure that should not exceed 90% of the service test pressure (which is stenciled on the hose) or the maximum operating pressure of the attached coupling.

 

The minimum kink test pressure shall be equal to at least one and one-half times the specified service test pressure.
