Multipurpose: can accommodate multiple line size and pressures
Only one fixture design needed for all the lines to be tested
By necessity fixture must be very large
If multiple fixtures are allowed for each line, fixtures can be made smaller and simpler targeted for each line
Self-contained: axial forces generated by pressure resisted completely by the test fixture
No functional advantage
Fixture must be designed large enough to handle all loads generated during testing
If some of the testing loads can be shared between the test fixture and line being tested, fixture may be able to be reduced in size
Integral: test fixture assembled as a complete unit
Allowing transportation of completed assembly and minimizing disassembly of complete fixture between tests
Complete assembly is very heavy and large requiring machinery for manipulation
If the new test fixture can be created as a modular design of smaller pieces, each piece could be manipulated by hand eliminating handling by machinery
