18、D OF BOILER Part 2, Inspection; and Part 3, Repairs and Alterations.The NBIC Committees function is to establish rules of safety governing post-construction activities for the installation, inspection, and repair and alteration of pressure-retaining items, and to interpret these rules when questions

19、 arise regarding their intent. In formulating the rules, the NBIC Committee considers the needs and concerns of individuals and organizations involved in the safety of pressure-retaining items. The objective of the rules is to afford reasonably certain protection of life and property, so as to give

20、a reasonably long, safe period of usefulness. Advancements in design and material and the evidence of experience are recognized.The rules established by the NBIC Committee are not to be interpreted as approving, recommending, or en-dorsing any proprietary or specific design, or as limiting in any wa

21、y an organizations freedom to choose any method that conforms to the NBIC rules.The NBIC Committee meets regularly to consider revisions of existing rules, formulation of new rules, and respond to requests for interpretations. Requests for interpretation must be addressed to the NBIC Secretary in wr

22、iting and must give full particulars in order to receive Committee consideration and a written reply. Pro-posed revisions to the code resulting from inquiries will be presented to the NBIC Committee for appropriate action.Proposed revisions to the code approved by the NBIC Committee are submitted to

23、 the American National Standards Institute and published on the National Board web-site to invite comments from all interested per-sons. After the allotted time for public review and final approval, the new edition is published. The Foreword, Introduction, Personnel and Index Sections of the NBIC ar

24、e provided for guidance and informational purposes only and shall not be considered a part of the Code. Theses sections are not approved by the NBIC Commit-tee or submitted to the American National Standards Institute.Organizations or users of pressure-retaining items are cautioned against making us

25、e of revisions that are less restrictive than former requirements without having assurance that they have been accepted by the Jurisdic-tion where the pressure-retaining item is installed.The general philosophy underlying the NBIC is to parallel those provisions of the original code of construc-tion

26、, as they can be applied to post-construction activities. The NBIC does not contain rules to cover all details of post-construction activities. Where complete details are not given, it is intended that individuals or organizations, subject to the acceptance of the Inspector and Jurisdiction when app

27、licable, provide details XVNB-23 2017FOREWARDfor post-construction activities that will be as safe as otherwise provided by the rules in the original code of construction.Activities not conforming to the rules of the original code of construction or the NBIC must receive specific approval from the J

28、urisdiction, who may establish requirements for design, construction, inspection, testing, and documentation.There are instances where the NBIC serves to warn against pitfalls; but the code is not a handbook, and can-not substitute for education, experience, and sound engineering judgment. It is int

29、ended that this edition of the NBIC not be retroactive. Unless the Jurisdiction imposes the use of an earlier edition, the latest effective edition is the governing document.XVINATIONAL BOARD INSPECTION CODE2017PERSONNELPERSONNEL The National Board of Boiler and Pressure Vessel Inspectors Board of T
