40、atare visible to the unaided eye and affect the wall integrity.9. Assembly9.1 Crimp JointsInsert fittings shall be joined to PEXtubing or PE-RT tubing by the compression of a copper crimpring around the outer circumference of the tubing, forcing thetubing material into annular spaces formed by ribs
41、on thefitting. Insert fittings and crimp rings shall meet the dimen-sional and material requirements of this standard. PEX tubingshall meet the requirements of Specification F876. PE-RTtubing shall meet the requirements Specifications F2623 andF2769 or a combination thereof. The dimensions and out-o
42、f-roundness of the crimp ring, after it has been crimped, shall bein accordance with Table 1.9.1.1 Crimping ProcedureThe crimping procedure shallbe as follows: slide the crimp ring onto the tubing, insert theribbed end of the fitting into the end of the tubing until thetubing contacts the shoulder o
43、f the fitting or tube stop. Forfitting sizes38 to 114 in. the crimp ring shall then be positionedon the tubing so the edge of the crimp ring is18 to14 in. (3.2to 6.4 mm) from the end of the tube. For 112 in. fitting size thecrimp ring shall be positioned14 to38 in. (6.4 to 9.5 mm) fromthe end of tub
44、e. For 2 in. fitting size the crimp ring shall bepositioned38 to12 in. (9.5 to 12.7 mm) from the end of thetube. The jaws of the crimping tool shall be centered over thecrimp ring and the tool shall be held so that the crimping jawsare approximately perpendicular to the axis of the barb. Thejaws of
45、the crimping tool shall be closed around the crimp ring,compressing the crimp ring onto the tubing. The crimp ringshall not be crimped more than once. Each crimp shall bechecked to determine conformance to the after-crimped dimen-sional requirements of Table 1.10. Product Marking10.1 Quality of Mark
46、ingThe marking shall be applied tothe fittings in such a manner that it remains legible afterinstallation and inspection.10.2 Content of Marking:10.2.1 Marking on fittings shall include manufacturersname or trademark, or some other identifying mark, and if sizepermits, PEX/PE-RT or the ASTM standard
47、 number, or acombination thereof.10.2.1.1 Where recessed marking is used on fittings, careshall be taken to see that the marking shall not cause cracks orreduce the wall thickness below the minimum specified.10.2.2 Marking on packaging shall include manufacturersname, fitting size, and ASTM F1807.10
48、.2.3 Crimp rings:10.2.3.1 Marking on crimp rings shall include manufactur-ers trademark, or some other identifying mark, and ASTMF1807.10.2.3.2 Manufacturer of crimp rings may use an alternateidentifying marking in place of the “black in color” providedthe ring is generally natural copper color with
