37、rity.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 on thefitting. Insert fittings and crimp rings shall meet
38、the dimen-sional and material requirements of this standard. PEX tubingshall meet the requirements of Specifications F876 or F877.PE-RT tubing shall meet the requirements of SpecificationF2769. The dimensions and out-of-roundness of the crimp ring,after it has been crimped, shall be in accordance wi
39、th 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 of the fitting or tube stop. Forfitting sizes38 to 114 in. the crimp ring shall the
40、n 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 tube. For 2 in. fitting size the crimp ring shall bepositioned38 to12 in. (9.5 to 12.
41、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 the crimping tool shall be closed around the crimp ring,compressing the crimp ring
42、 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 .SizeAOutsideDiameterof RibABMinimumIDDDistance toFirst RibBLMinimumInsertLengthAHMinimumRibHeightNumberof RibsCWRibDWidt
