2.1 References
Codes, standards, and specifications containingprovi- sions to the extent referenced herein constitute require- ments of this Standard. These reference documents are listed in Mandatory Appendix II.
2.2 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.
2.3 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 separate tables that appear in Mandatory Appendix I. The values stated in each system are not exact equiva- lents; 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.
2.4 Quality Systems
Requirements relating to the product manufacturer’s quality system programs are described in Nonmandatory Appendix B.
4 SIZE
The sizes of the fittings shown in Table 1 (Table I-1) correspond to standard water tube size as defined in ASTM B88.
5 MARKING
Each fitting shall be marked with the manufacturer’s name or trademark and other applicable markings as required by MSS SP-25. Marking of fittings less than nominal size 1 ⁄ 2 is optional.
6 MATERIAL
Castings shall be copper alloy produced to meet the following:
(a) the requirements of ASTM B62 UNS alloy C83600 or
(b) the chemical and tensile requirements of ASTM B584 UNS alloy C83800 or C84400 and in all other respects shall complywith the requirementofASTM B62
