![]() ![]() The designer is responsible for complying with Code rules and demonstrating compliance with Code equations when such equations are mandatory. The Committee recognizes that tools and techniques used for design and analysis change as technology progresses and expects engineers to use good judgment in the application of these tools. The phrase engineering judgement refers to technical judgments made by knowledgeable engineers experienced in the application of the Code.Įngineering judgments must be consistent with Code philosophy, and such judgments must never be used to overrule mandatory requirements or specific prohibitions of the Code. The Code is not a handbook and cannot replace education, experience, and the use of engineering judgment. ![]() The Code does not address all aspects of these activities and those aspects that are not specifically addressed should not be considered prohibited. This Code contains mandatory requirements, specific prohibitions, and nonmandatory guidance for construction activities and inservice inspection and testing activities. The objective of the rules is to afford reasonably certain protection of life and property, and to provide a margin for deterioration in service to give a reasonably long, safe period of usefulness.Īdvancements in design and materials and evidence of experience have been recognized. In formulating the rules, the Committee considers the needs of users, manufacturers, and inspectors of pressure vessels. Users of the Code should refer to the pertinent codes, standards, laws, regulations, or other relevant documents for safety issues other than those relating to pressure integrity.Įxcept for Sections XI and XII, and with a few other exceptions, the rules do not, of practical necessity, reflect the likelihood and consequences of deterioration in service related to specific service fluids or external operating environments. This Code does not address other safety issues relating to the construction of boilers, pressure vessels, transport tanks, or nuclear components, or the inservice inspection of nuclear components or transport tanks. The technical consistency of the Sections of the Code and coordination of standards development activities of the Committees is supported and guided by the Technical Oversight Management Committee. The Committee also interprets these rules when questions arise regarding their intent. Where reference is made to "the Committee" in this Foreword, each of these committees is included individually and collectively. CODE CASESThe Boiler and Pressure Vessel Code committees meet regularly to consider proposed additions and revisions to the Code and to formulate Cases to clarify the intent of existing requirements or provide, when the need is urgent, rules for materials or constructions not covered by existing Code rules. Interpretations issued during the previous two calendar years are included with the publication of the applicable Section of the Code in the Edition.
