Data Report Registration
Print Date: 4/30/2025 11:11:21 PM
NBBI maintains permanent records of pressure-retaining items that are registered by individual manufacturers who meet a set of requirements. Registration with NBBI indicates that a pressure-retaining item is constructed in accordance with the ASME Boiler and Pressure Vessel Code (ASME Code) and is inspected by a qualified NBBI Commissioned Inspector. Registration represents the culmination of a three-step process: the design and construction of an item in accordance with the ASME Code, inspection by an NBBI Commissioned Inspector, and final documentation certifying compliance with the ASME Code.
Any manufacturer meeting the requirements of NB-264, Criteria for ASME Registration may become authorized to register. There is no charge to become authorized to register, but there is a fee for each item registered.
To apply for authorization to register, please go to the online Application for Authorization to Register.
Manufacturers may register printed original data reports or may set up a National Board Electronic Data Transfer (EDT) account and register items electronically.
A History of National Board Registration is included for reference.
A listing of manufacturers and repair organizations authorized to register is presented in a searchable format in the Manufacturer & Repair Directory.
The NB mark is used by manufacturers to identify items registered with the National Board. It is also used by pressure relief device manufacturers and assemblers to identify pressure relief devices that have been certified by the National Board in accordance with NB-501, National Board Certification of Pressure Relief Devices.
American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME BPV Code)/National Board Inspection Code (NBIC) Data Report Forms Revisions
The 2023 revisions to the ASME BPV Code and NBIC report forms became mandatory on January 1, 2024. Items manufactured/altered/repaired to the 2023 codes must be documented on the current forms.
All data report forms submitted to the National Board for registration on outdated forms will be returned for correction.
Data report forms submitted for registration to the National Board in paper must also meet the following requirements:
- Data report forms must be in the exact format and have the same content as those found in the ASME BPV Code and the NBIC.
- Two-sided data report forms (BPV Section IV forms - the second page says “Back”) must be submitted as such. It is not acceptable to submit these data report forms on two separate pages.
- The header must be completed on each page of data report forms that will be submitted on multiple pages (Ex. U-1, U-2, P-3). There must also be space for the company representative and authorized inspector to initial each page.
- All data report forms and their content must comply with the National Board’s font size requirements. The National Board requires the use of at least a 6 point font size in creating data report forms and at least an 8 point font size on any technical information provided on the data report form (Arial 8 or comparable size in any other font style). The only exception to this will be in sections which have a table format (example: heads and nozzles). In these sections, a 7 point font will be acceptable if the data remains legible.
- Data report forms, including all attachments (supplemental sheets and partial data report forms), submitted for registration must be legible. The legibility of data reports is subject to review/acceptance by the National Board staff.
In order to minimize the impact of the recent revisions, consideration should be given to using the National Board’s Electronic Data Transfer (EDT) System for submitting data reports for registration. EDT simplifies the entire process, eliminates the return of data reports for non-conformance issues and ensures the most up-to-date forms.
