1.2 References
Codes, standards, and specifications, containing provisions to the extent referenced herein, constitute requirements of this Standard. These refereflce documents are listed in Mandatory Appendix TI.
1.3 Convention
For the purpose ot determining con forrnance with this Standard, the convention for fixing significant digits, where units or maximum or minimum values are sped- lied, shall be “rounding off” as defined in ASTM E 29, Standard Practice for Using Significant Digits in Test Data to Determine Conformance with Specifications. 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.
1.4 Relevant Units
This Standard states values in both metric and US. 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. 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.
The fittings covered by this Standard are designed fora maximum cold water service-pressure of 1 200 kPa(175 psig).
The sizes of the fittings shown in Table 1 (Table 1-1)correspond to standard water tube size as defined inASTM B 88.
Each fitting shall be marked with the manufacturer’sname or trademark and other applicable markings asrequired by MsS SP-25,Standard Marking System forValves, Fittings, Flanges and Unions. Marking of fittingsless than nominal size is optional.
Castings shall be copper alloy produced to meet thefollowing:
(a)the requirements of ASTM B 62,Standard Specifi-cation for Composition Bronze or Ounce Metal Castings,UNS C83600; or
(b) the chemical and tensile requirements of ASTMB584,Standard Specification for Copper Alloy SandCastings for General Applications,UNs c83800 orC84400, and in all other respects shall comply with therequirement of ASTM B 62.
