b Gaging Practice for Alternate Pipe Connections
The iiunufacturcr shall own or base access to gages and working gages.
c. The usc of master gages in checking prnducl threads should be minimized. Such use should he confined 10 cases of dispute which cannot be settled by rechecking the working gage against the rekicnce master. Good care should be evercised when the master gage is assembled on a product thread.
5.4 REQUAUFICAT1ON
5.4.1 Requaliticatiori Tests for Pipe and Prime Connection
Changes as described in Appendix A br previously qualitied systems shall require the following minimum tests:
The king-term static 11145 shall he verified at I5Oi or higher temperature if so rated, after any changes as described in Appendix A by crnducting the abridged ASTM D 2992 Procedure H free-endi test as cksciibcd in Secuon 12 o’ A.STM 1)2992. Test samples shall he assembled by the manufacturer’s documented make-up procedure.
Test samples shall be a size no smaller than 2 in. nominal diameter. The same outside diameter to reinforced wall ratio (flI) constraints as in 5.1.1 shall apply for requalilication.
5.4.2 Requalitication Tests for Other Components
The requalihcation tests of 5.1.2. 5.1.3 and 5.1.4 shall be repeated after any change as described in Appendix A.
6 Process of Manufacture and Material
