BSPP 60 cone fittings Performance qualification test

Date:Jun 11, 2019


BSPP 60 cone connector fittings is according to ISO 8434 6 standard, it is more details than BS5200 fittings catalogue.


ISO 8434 6 including Test pressures for 60° cone connectors; Proof test, Burst test, Cyclic endurance (impulse) test, Vacuum test, Overtightening test, Re-use of test samples etc as follows:


The connectors shall be tested at the lower of the test pressure specified in Table 3 or in the standard for the relevant stud end, i.e., ISO 1179-2, ISO 1179-3 or ISO 6149-3. All components requiring copper brazing for assembly shall be processed through a 1 000 °C minimum annealing process before burst, cyclic endurance or

overtightening testing.

Proof test

For each size and nipple, nine test assemblies in accordance with ISO 19879 shall be subjected to the proof test procedure specified in ISO 19879, prior to burst and cyclic endurance tests. They shall not leak at the proof pressures

Burst test

Three of the test assemblies that had been subjected to the proof test in 15.1.2 shall be used for the burst test. The test shall be conducted in accordance with the burst test procedure specified in ISO 19879 and at the minimum torque values given in Table 4. The test assemblies shall meet or exceed the minimum required burst pressures.


Cyclic endurance (impulse) test

The remaining six test assemblies that had been subjected to the proof test in 15.1.2 shall be subjected to the cyclic endurance test procedure specified in ISO 19879. The test shall be conducted at minimum torque values given in Table 4. The test assemblies shall pass a cyclic endurance test for 1 000 000 cycles at the respective

impulse pressures.


Vacuum test

For each size and nipple style, two test assemblies in accordance with ISO 19879 shall be subjected to the vacuum test procedure specified in ISO 19879. Connectors shall be capable of withstanding a vacuum of 6,5 kPa (0,065 bar) absolute pressure for 5 min without leakage.


Overtightening test

For each size, nipple style and swivel nut design, three samples shall be subjected to the overtightening test specified in ISO 19879. Connector swivel nuts shall be capable of withstanding the overtightening qualification test with no indication of failure when torqued to the overtorque values given in Table 4.


Re-use of test samples

Parts used for cyclic endurance, burst or overtightening test shall not be tested further, used or returned to stock.
