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 described in NB-415, Accreditation of R Repair Organizations.
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 National Board Inspection Code (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).
- Certification Fees
The fee for the R Certificate of Authorization (three-year period) is $630 USD.
- Joint Review Fees
Joint Reviews may be done by the member jurisdiction or by the National Board, depending upon jurisdictional requirements. Contact the National Board Accreditation Department to determine who will perform the joint review of your facility. Reviews performed by the jurisdiction may require fees, which are determined by the member jurisdiction. Click on Members to contact your jurisdiction. If the National Board performs the joint review, an advance deposit is required, as described below:
- Within the Continental US – $4,000 USD
- Outside of the Continental US – Contact Us for estimated cost and payment methods.
After completion of the joint review and actual cost has been determined, the applicant will be provided with a statement with the amount due or a refund amount.
Applicants who change or cancel their joint review will be charged a cancellation fee of $315 USD.
Organizations holding an R Certificate of Authorization and changing their ownership, name, location, and/or scopes must submit a revised application along with a copy of their quality control manual cover sheet, statement of authority page, and an inspector signature indicating acceptance of the changes.
The appropriate jurisdiction will be notified, and that jurisdiction may require a joint review of the facilities and quality control manual.
