ASME B16.23:2011 pdf free download.Cast Copper Alloy Solder Joint Drainage Fittings:DWV.
7 MARKING
(a) Each fitting shall be marked permanently and legibly with the manufacturer’s nanw or trademark and with “DWV” (to indicate Drain Waste Vcnt).
(b) Vent fittings shall be permanently marked ‘VENT ONLY” (See Tables 43, 44, 1-43, and 1-44) and show the manufacturer’s name or trademark in accordance with
MSS SP-25.
8 MATERIAL
Castings shall be copper alloy produced to meet
(a) the requirements of ASTM B62 Alloy C836(*i; or
(b) the chemical and tensile requirements of ASTM l35t4 Alloy $3H00 or $4400, and in all other respects comply with the requirements of ASTM 862.
9 METAL THICKNESS
Dimensional variations will twcur in the casting process. Pattern equipment shall be designed to produce the metal thickness given for fittings in Table 2 or Table 1-2.
Any final fitting metal wall thickness less than 0% of the thickness given in the table is unacceptable.
10 INSPECTION TOLERANCE
10.1 ConventIon
For determining conformance with this Standard, the convention for fixing significant digits where limits (maximum and minimum values) are specified shall be as defined in ASTM E29. This requires that an observed or calcuLated value be rounded oil to the nearest Unit in the last right-hand digit used for expressing the limit. Decimal values and tolerances do not imply a particular method of measurement.
10.2 Linear Dimensions
DWV fittings covered by this Standard shall conform to the laying lengths specified in Tables 4 through 56 and Tables 1-4 through 1-56. An inspection tolerance, as shown in Table I or Table I-I, shall be allowed on center- to-shoulder, center-to-threaded end, and shoulder-to- threaded end dimensions on all fittings having internal solder (cup) ends; and on center-to-solder end, solder end-to-shoulder, and solder end-to-threaded dimensions on all fittings having external solder (fitting) ends. The largest opening in the fitting governs the tolerance to be applied to all openings.
The inspection tolerance for laying length dimensions A. B. and C (in Table 4 or Table 1-4) shall be double those shown above, except the minus tolerance applied to couplings; dimension A shall not result in a dimensionless than 2.3 mm (0.09 in.).
10.3 Ovality
Maximum ovality shall not exceed 1%of the maxi-mum diameters shown in Table 2 or Table 1-2.The aver-age of the maximum and minimum diameters shall bewithin the dimensions shown in the table.
10.4 Alignment
The maximum allowable variations in the regularalignment of all openings shall be 5 mm per 1 m (0.06 in.per 1 ft).
10.5 Gaging of Solder Joint Ends
(a)Standard Gaging MeElod of Solder Joinf Ends.Thestandard method of gaging the diameter tolerances formale and female ends shall be by the use of plain plugand ring gages designed to hold the product within thelimits established in Table 2 or Table I-2.
bOptional Gaging Method of Solder Joint Ends. Forgaging the diameter tolerance of male and female ends,the manufacturer may use direct reading instrumentsinstead of ring and plug gages as specified in para.(a).When gaging the diameters of male and female ends,using direct reading instruments,refer to para.10.3.
