VR Certificate of Authorization
The National Board offers the Certificate of Authorization and VR Stamp for the repair of pressure relief valves. Requirements are described in NB-514, Accreditation of VR Repair Organizations.
Organizations seeking a National Board VR Certificate of Authorization must complete and submit the following:
- 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 parts of the NBIC. 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; and,
- have available a copy of the Code of Construction appropriate for the intended scope of work.
Prior to issuance of a National Board VR Certificate of Authorization, the organization and its facilities are subject to a review of its quality system. An important part of that review will be the witnessing of the repair of several sample pressure relief valves.
An independent test for operation and capacity of these sample pressure relief valves will be conducted at a National Board-accepted laboratory. The test is to verify the repaired valves meet applicable ASME Code requirements for performance and relieving capacity.
- The National Board Testing Laboratory is available to perform this testing, along with several other major valve manufacturers which operate National Board-accepted testing laboratories.
- A National Board representative will witness the valve testing.

Pressure Relief Department staff will contact you to schedule a date for the review of the VR Quality System and its implementation, and to witness the repair of the required sample pressure relief valves.
The fee for renewal of the VR Certificate of Authorization is $660 USD for a three-year period. For new issuances, there will be an additional one-time charge of $75 USD for the loan of the steel VR symbol stamp.
The review of an organization’s quality control system for VR certification, conducted by the National Board, can be performed in conjunction with its ASME review, where applicable, or as a standalone VR review. The National Board requires an advance deposit to schedule reviews for ASME/VR certifications or the standalone VR certification, as shown below:
|Within the Continental US
|Alaska, Caribbean, Hawaii, Mexico
|Africa, Asia, Australia, Russia, South America
If your location is not included in the above list, please contact the National Board Pressure Relief Department.
Withdrawal of an application in-process will result in a $330 USD cancellation fee. If a review has been scheduled and is cancelled, other cancellation fees may apply.
Organizations holding a VR Certificate of Authorization who are having a name change prior to renewal must submit an NB-519, National Board VR, T/O, and/or NB Certificate of Authorization Name Change Application, along with a copy of their Quality Control Manual revisions. There is a fee of $50 USD for a name change to a certificate.
NOTE: If the name change is being done at the time of renewal, an NB-519 does not need to be submitted, and the $50 revision fee is not needed. The name change should be noted on the NB-550 application for renewal.
Organizations holding a VR Certificate of Authorization who are having a location change or scope change, must submit an NB-550, Application for the National Board VR and/or T/O Certificate of Authorization. A review of your facility may be required prior to issuance of a revised certificate. Cost will be determined upon receipt of the NB-550.
