As a member isso. Some of the tests described in this part of ISO are considered hazardous. Use the same procedures as in 5. Dimensions list any exceptions: Stud ends with metal-to-metal sealing type B. The distance between the centrelines of test ports shall be a minimum of 1,5 times the port diameter. This report is based on accounts to which one of the following applies:.
Major international companies that have used these connectors have adopted the design without noting any problems. Fitting and stud end standards 1. Seals shall conform to their respective dimensional requirements, and O-rings shall meet or exceed the quality requirements for grade N general purpose of ISOif applicable. The threads are integral to themselves, connectors of this type match only to themselves and, other than having metric threads, no value in changing could be found.
Testing of six samples to confirm that they are capable of withstanding the overtorque qualification test when tested to the overtorque values shown in their respective standards. Cold-reduced carbon steel sheet of commercial All components tested shall be tested in the final form as the customer receives the partincluding annealing as required for brazing. Reference number ISO Quality management systems —. Components may be connected through their ports by connections connectorstubes and hoses.
Heavy-duty S series and light-duty L series stud ends with elastomeric sealing type E. Profile of Global Survey Sample.
Also, the isso overtorque and seal performance 84344-2 been extensively tested; to change to metric threads would require an extensive test program at considerable cost without providing any functional improvement.
Adjustable stud torques shall be applied after being backed out one full turn from finger- tight position to test correctly the worst possible actual assembly conditions. Test methods for threaded hydraulic fluid power connections Reference number ISO The distance between the port centreline and the edge of the test block shall be a minimum of 1 times the port diameter.

It is therefore essential that, in conducting these tests, all appropriate safety precautions are strictly adhered to.
Connections shall be restrained during the test uso the wrench shall be located at the threaded end of the nut hex. Metallic tube connections for fluid power. Test results and test conditions oso be reported on the test data form given in annex A. Testing of two samples to confirm that they are capable of withstanding a vacuum of 6,5 kPa 0, bar absolute pressure for 5 min without leakage.
