Codes, standards, and specifications, containing provisions to the extent referenced herein, constitute requirements of this Standard. These reference documents are listed in Mandatory Appendix IL
1.3 Convention
For the purpose of determining conformance with this Standard, the convention for fixing significant digits, where units or maximum or minimum values are specified, shall he “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 U.S. Customary units. These systems of units arc 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.
1.5 Quality Systems
Requirements relating to the product manufacturer’s quality system programs are described in Nonmandatory Appendix B.
1.6 Service Conditions
Criteria for selection of materials suitable for particular fluid service are not within the scope of this Standard.
The fittings covered by this Standard are designed for a maximum cold water service-pressure of 1 200 kPa (175 psig).
The sizes of the fittings shown in Table I (Table I-i) correspond to standard water tube size as defined in
ASTM B 88.
Each fitting shall be marked with the manufacturer’s name or trademark and other applicable markings as required by MSS SP-25, Standard Marking System for Valves, Fittings, Flanges and Unions. Marking of fittings less than nominal size is optional.
Castings shall be copper alloy produced to meet the following:
(a) the requirements of ASTM B 62, Standard Specification for Composition Bronze or Ounce Metal Castings, UNS C83600; or
(b) the chemical and tensile requirements of ASTM
B 584, Standard Specification for Copper Alloy Sand Castings for General Applications, UNS C83800 or C84400, and in all other respects shall comply with the requirement of ASTM B 62.ASME B16.26 pdf free download.
