ASME B16.29:2017 pdf free download – Wrought Copper and Wrought Copper Alloy Solder-Joint Drainage Fittings – DWV
1 SCOPE
This Standard for wrought copper and wrought copper alloy solder-joint drainage fttings, designed for use with copper drainage tube conforming to ASTM B306, covers the following:
(a) description
(b) pitch (slope)
(c) abbreviations for end connections
(d) sizes and method of designating openings for redu-cing fttings .
(e) marking
(f) material
(g) dimensions and tolerances
2.1 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 off 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.
2.2 Relevant Units
This Standard states values in both SI (metric) and U.S. Customary units. These systems of units are to be regarded separately as standard. Within the text, the U.S. Customary units are shown in parentheses or in sepa- rate tables that appear in Mandatory Appendix I. The values stated in each system are not exact equivalents; therefore, it is required that each system of units be used independently of the other. Combining values from the two systems constitutes nonconformance with the Standard.
2.3 References
Codes, standards, and specifications, containing provi- sions to the extent referenced herein, constitute require- ments of this Standard. These reference documents are listed in Mandatory Appendix II.
2.4 Quality Systems
Guidelines relating to the product manufacturer’s quality system programs are described in Nonmandatory Appendix A.
3 DESCRIPTION
These fittings are designed for drainage and vent systems only, using the solder-joint method of connection. The ftting cups (C) are provided with stops so that the ends of the tube, when assembled, meet the stops. Sketches and designs of fttings are ilustrative only. The dimensions specified herein shall govern in all cases.
4 PITCH (SLOPE)
All nominal 90-deg fttings shall be pitched to result in a slope of 0.20 mm/m (0.25 in./ft) (2%) of horizontal tube length with reference to a horizontal plane.
