Standard Specification for General Requirements for Steel Plates for Pressure Vessels
1.1 This general requirements specification2 covers a group of common requirements that, unless otherwise specified in the applicable product specification, apply to rolled steel plates for pressure vessels covered by each of the following product specifications issued by ASTM:...
1.2 Appendix X1 provides information on coil as a source of plates for pressure vessels.
1.3 Appendix X2 provides information on the variability of tensile properties in plates for pressure vessels.
1.4 Appendix X3 provides information on the variability of Charpy-V-Notch impact test properties in plates for pressure vessels.
1.5 Appendix X4 provides information on cold bending of plates, including suggested minimum inside radii for cold bending.
1.6 These materials are intended to be suitable for fusion welding. When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized.
1.7 In case of any conflict in requirements, the requirements of the applicable product specification prevail over those of this general requirements specification.
1.8 Additional requirements that are specified in the purchase order and accepted by the supplier are permitted, provided that such requirements do not negate any of the requirements of this general requirements specification or the applicable product specification.
