1.4 References
Standards and specifications adopted by reference in this Standard are shown in Mandatory Appendix II, which is part of this Standard. It is not considered practical to identify the specific edition of each standard and specification in the individual references. Instead. the specific edition reference is identified in Mandatory Appendix II.
1.5 Ouality Systems
Requirements relating to the product manufacturer’s Quality System Programs are described in Nonmandatory Appendix B.
2 PRESSURE-TEMPERATURE RATINGS
2.1 Rating of System
The internal working pressure-temperature rating for a braze-joint system is dependent upon, not only fitting and tube strength, but also selection of valves and appurtenances.
Pressure-temperature ratings for fittings and braze joints to the dimensions of Table 3 (Table 13), made with typical commercial brazing materials, shall be considered equal to the values given in Table 1 (Table Ii).
The internal working-pressure rating of the system shall be the lowest of the values shown in Table 1 (Table II) and those of the tube, valves, or appurtenances.
2.2 Fitting Bursting Strength
Fittings manufactured to this Standard shall have an ambient-temperature bursting-strength of at least four times the 38°C (100°F) rated internal working-pressure as shown in Table 1 (Table II).
