VR Stamp


VR Stamp Certificate of Authorization Program

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.

Prerequisites

Organizations seeking a National Board VR Certificate of Authorization must complete NB-550, Application for National Board VR Certificate of Authorization to Repair Pressure Relief Valves, NB-552, Control Sheet, NB-564, Terms and Conditions and:

  1. 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,
  1. have the current edition of all three 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,
  1. 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.

Return forms by e-mail to: prd@nationalboard.org or mail the forms to:

          National Board Test Laboratory
          7437 Pingue Drive
          Worthington, Ohio 43085

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.
