ASME B16.51:2013 pdf free download.Copper and Copper Alloy Press-Connect Pressure Fittings.
Seamless Copper Water Tube. The sue designations of the threaded ends correspond to nominal pipe size as shown in ASME 131.20.1.
Fittings shall be designated by the size of the openings in the sequence illustrated in Fig. 1.
5 MARKING
Each fitting shall be permanently marked with the manufacturer’s name or trademark in accordance with MSS SP-25. Marking on fittings Less than nominal size
or on any fitting where it damages joining surfaces is not required.
6 MATERIAL
61 Wrought Copper Alloys
(a) Fittings shall be made from copper UNS alloy number Cl 0200, C1201X). C12200, or C23(m.
(b Other coppers and copper alloys shall be permitted, provided their chemical composition contains a minimum of 114% copper and a maximum of l(% zinc, and provided the fittings produced from the copper alloy meet all the mechanical and corrosion-resistant properties for the end purposes of the fittings. For pota. ble water applications, fittings shall be produced from low lead (0.25% or less) copper alloys and shall meet all the mechanical and corrosion-resistant properties for the end purposes of the Fittings. The composition of the copper alloy shall not inhibit pining to the tube or to other fittings
6.2 Cast Copper Alloys
(a) Castings intended for use in applicatioim up to 2(WC (400°F) shall be of a copper alloy produced to meet
(1) the requirements of ASTM B62 UNS alloy number C830, or
(2) the chemical and tensile requirements of ASTM 115114 UNS alloy number C83800 or C8440() and in all other respects the requirements of ASTM 1362
(b) Castings intended for use in potable water applications up to 93°C (200°F) shall be low lead (0.25% or less) and shall be
(1) of a copper alloy produced to meet the requirements of ASTM 115K4 UNS alloy number C87850 or C89833, or
(2) of other cast copper alloys, provided the fittings produced meet mechanical and corrosion-resistant properties needed for potable water application
6.3 Elastomers (Seals)
Ebstomeric components shall be resistant to microbiological attack and oione attack, and shall contain inhihitor to prevent copper degradation. The etastomer shall be an ethylene propylene diene monomer (HDM) and shall meet the minimum property and test requirements.
(C) Z3 designates chloramine resistance that is determined by testing br 1 008 h at 70CC (158F) per ATM D62$4 a solution containing 50 ppm total chinrine this shall be checked and refreshed daily. Upon completion of the test, the change in volume shall be less than 30%, and the change in durometer hardness shall be a maximum of 6. There shall be no visual degradation of the ebstomeric material.
(d) Z4 designates resistance of the elastomer to copper degradation. The test shall be conducted in accordance with para. 14.9.1 of this Standard. Upon completion of the test, the change in volume shall be less than 30%, and the change in durumeter hardness shall be a maximum of 6. There shall be no visual degradation of the elastomeric material.
6.4 Seal Lubricant
The only seal lubricant that shall be used is that specified by the manufacturer.
