Burst Pressure Under Static Conditions

The pressure at which the entire catheter assembly bursts.

Test Procedure

Catheter is connected to a pressure manifold and hubs are securely locked. Distil end of the catheter is occluded with a clamp. Catheter is immersed in the fluid at a set temperature of 37C.Hydraulic volume source is applied to the catheter until sufficient force causes the catheter to leak or rupture. Burst or maximum pressure is recorded. If pressure can no longer be increased a leak may be present, and the source of the leak needs to be investigated. Note: This is a potentially hazardous test and great care should be taken to ensure the operator can conduct the test safely.

Equipment

The test is performed with an automatic inflation/deflation system.
