1.1.1 This specification also covers a group of supplementary requirements which are applicable to several of the above specifications as indicated therein. These are provided for use when additional testing or inspection is desired and apply only when specified individually by the purchaser in the order.
1.2 Appendix X1 describes the production and some of the characteristics of coiled product from which pressure vessel plates may be produced.
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 individual material specification shall prevail over those of this general specification.
1.8 The purchaser may specify additional requirements which do not negate any of the provisions of this general specification or of the individual material specifications. Such additional requirements, the acceptance of which are subject to negotiation with the supplier, must be included in the order information (see 4.1.8).
1.9 For purposes of determining conformance with this specification and the various material specifications referenced in 1.1, values shall be rounded to the nearest unit in the right-hand place of figures used in expressing the limiting values in accordance with the rounding method of Practice E29.
1.10 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents. Therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.
1.11 This specification and the applicable material specifications are expressed in both inch-pound units and SI units. However, unless the order specifies the applicable 'M' specification designation (SI units), the material shall be furnished to inch-pound units.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
