1、FORD LABORATORY TEST METHOD BP 008-04 2001 0822 BURST TEST OF OPEN WEAVE REINFORCED RUBBER HOSE Revised Editorial - no technical change A. Cockman Application This is a procedure to determine the burst strength of open weave reinforced rubber hose. The bursting pressure is applied by means of hydros

2、tatic pressure. Apparatus Required Metal Plugs or Cones Must have an interference fit on the I.D. of the hose being checked. One plug or cone must have a fitting which will provide for the opening on the hydrostatic tester; the other plug or cone must have a suitable valve to purge the air from the

3、hose prior to the application of hydrostatic pressure. Note: Leading edges of plugs must not damage tube of hose. Hose Clamps (2) Clamps or clamping devices to provide enough force so that no leakage or damage occurs while hose is being tested. Hydrostatic Tester Must have valves and gage system to

4、provide for the rate and pressure required. Gage provided with scale not to exceed three times the approximate burst strength of the hose. A typical hydrostatic tester is shown in the sketch on page 3. Note: test. Cabinet must be shielded and proper drainage outlet provided for outlet of water after

5、 burst Pump or Pressure System Must provide a rate rise of 1000 psi/minute +/- 10 % (70.30 kilograms per sq cm +/- 10 %). A typical pump used is Northern Nitralloy Rotary Gear Pump, or equivalent.

7、testing and tested under the same conditions unless otherwise specified. 1. 2. 3. 4. 5. Procedure Hoses shall be tested in the finished length up to 610 mm distance between fittings. Longer hoses may be cut to 610 mm. These must include the most severe bend. Insert metal plugs or cones in the hose t

8、o be tested and then attach appropriate clamps. In no case shall the plugs or cones be inserted beyond the transition area or point of bend. The plugs or cones must have an interference fit with the hose I.D. or the dimension specified in the Engineering drawing. One end of the hose must be free and

9、 unrestrained. Apply water to the system, open valve to remove the air from the hose until a steady flow of water is obtained. Caution: Apply water pressure at the rate rise of 1000 psi/min +/- 10 % (70.30 kg per sq cm). Record hydrostatic burst strength as shown by the maximum gage reading. Be sure
