The National Board offers the Certificate of Authorization and R symbol stamp for the repair and/or alteration of boilers, pressure vessels, and other pressure-retaining items. Requirements are included in the current edition of the National Board Inspection Code (NBIC), Part 3, Section 1.
Organizations seeking a National Board R Certificate of Authorization must complete NB-12, Application for the National Board R Certificate of Authorization and:
- have and maintain an inspection agreement with an authorized inspection agency;
- have a written quality system that complies with the requirements of the current edition of the NBIC and includes the expected scope of activities;
- have the current edition of all three parts of the NBIC*; and
- have available a copy of the code of construction appropriate to the intended scope of work.
*Organizations have the option of using either a printed version or an electronic version, including a subscription from a National Board licensed reseller, to fulfill this requirement.
Prior to issuance of a National Board R Certificate of Authorization, the organization and its facilities are subject to a review of its quality system (referred to as a Joint Review).
The holder of an ASME Code Symbol Stamp whose facilities were reviewed (with the exception of V, UV ,HV ,NV , and H [cast iron]), may obtain National Board authorization without a review of its facilities, provided the organization has a Quality System to cover the scope of repairs or alterations to be made, and the application for the R Certificate of Authorization is submitted within 12 months from the issuance of the ASME Certificate of Authorization. The R Certificate of Authorization will be issued to expire concurrent with the ASME Certificate of Authorization. Subsequent certificates will be renewed upon a successful review and implementation of the quality system.
For current R stamp holders or new applicants that also have or are applying for new ASME Certificate(s) of Authorization, and are located in a jurisdiction in which ASME conducts the review, note that your R review may be conducted in conjuction with your scheduled ASME review, provided the assigned ASME Team Leader also represents the National Board of Boiler and Pressure Vessel Inspectors. Confirmation of the inclusion of the R review will be sent in a separate letter from the National Board.
