34、imensions and Tolerances of Fittings and Compression SleevesF1865 0939.1.1 Solder Joints Soldering of fittings joints shall becompleted prior to installation of the PEX tubing. Excessiveheat from the soldering operation will damage the PEX tubing.9.2 Assembly ProcedureTo affix the mechanical cold ex
35、-pansion insert fitting with compression sleeve to the PEXtubing, the procedure shall be as follows: Cut the tubing squareusing a cutter designed for plastic tubing. Inspect the end forburrs or foreign debris. Slide the compression sleeve onto thetubing at least 1 in. (25 mm) beyond the end of the t
36、ube. Insertthe properly sized expansion tool (see Note 1) fully into thetubing until the end of the tube meets the stop on the tool.Expand the tubing to the fullest reach of the tool. The fullestreach of the tool shall not expand the inside diameter of thetubing more than 0.20 in. (5.0 mm) for sizes
37、 up to58 in.nominal and 0.24 in. (6.0 mm) for larger sizes up to 1 in. Insertthe fitting into the expanded tube. Place the joining tool ontothe fitting assembly in accordance with the tool manufacturersinstructions (see Note 1). Operate the joining tool to slide thecompression sleeve over the tubing
38、 and until it reaches the stopon the fitting. Remove the joining tool. Compression sleevesthat are damaged in any way shall not be re-used.NOTE 1Tool manufacturers provide a variety of expansion tools andjoining tools with adapters for use on the various fittings configurationsand sizes. These tools
39、 may utilize mechanical, electrical, hydraulic, orpneumatic devices to actuate their mechanisms. One inch sizes may notrequire expansion.10. Quality Assurance10.1 When the product or product packing is marked withtheASTM designation F1865, the manufacturer affirms that theproduct was manufactured, i
40、nspected, sampled, and tested inaccordance with this specification, and has been found to meetthe requirements of this specification.11. Product Marking11.1 Quality of MarkingThe marking shall be applied tothe fittings in such a manner that it remains legible afterinstallation and inspection.11.2 Co
41、ntent of Marking:11.2.1 Marking on fittings shall include manufacturersname or trademark, or some other identifying mark. Additionalmarking shall includeASTM standard number and PEX, if sizepermits.11.2.1.1 Where recessed marking is used on fittings, careshall be taken to see that in no case shall t
42、he marking causecracks or reduce the wall thickness below the minimumspecified.11.2.2 Marking on packaging shall include manufacturersname, fitting size, and ASTM F1865.11.2.3 Markings on compression sleeves shall includemanufacturers trademark or some other identifying mark andASTM F1865.11.3 When
