4、esign, workmanship,minimum dimensions, marking, test methods, and qualitycontrol.1.2 Pressure rating of the fabricated-fitting design is beyondthe scope of this standard and shall be established by the fittingmanufacturer. This specification includes requirements for bothelevated temperature pressur
5、e-tests and short-term pressuriza-tion tests to demonstrate a reasonable level of performance ofthe fabricated-fitting design at the pressure rating establishedby the fitting manufacturer.1.3 The pressure-tests requirements are specified by thefittingsequivalent (E) DR. The EDR specified is the DR o
6、f thepiping system for which the fabricated fitting is intended to bebutt-fused.1.4 The text of this standard references notes and footnoteswhich provide explanatory material.
