Data Report Registration

Print Date: 9/23/2023 9:10:15 AM

Registration of an item with the National Board involves the manufacturer submitting an original manufacturer’s data report to the National Board for permanent retention. Registration is more than record retention; it represents the culmination of a three-step process, including the design and construction of an item in accordance with the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME BPV Code), the inspection by a National Board commissioned inspector, and the final documentation certifying compliance with the ASME BPV 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.

NB Mark

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 2021 revisions to the ASME BPV Code and NBIC report forms became mandatory on January 1, 2022. Items manufactured/altered/repaired to the 2021 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All data report forms submitted to the National Board for registration on outdated forms will be returned for correction.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 to the National Board for registration must also meet the following requirements:

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.
