1 National Board Authorization and Accreditation Programs

2 Authorization Programs Prior to 1921, a boiler manufactured in one state would not necessarily be accepted for operation in a neighboring state even if it had been constructed in accordance with the ASME code. States and several large cities had their own qualification requirements for inspectors, which, in most cases, meant little or no reciprocity. For a boiler to be installed in a state other than in which it was manufactured required inspections to be performed during fabrication by an inspector from the state where the boiler would be installed. This was costly and discouraged boiler sales across state borders.

3 After its founding in 1919, The National Board of Boiler and Pressure Vessel Inspectors knew an answer to the problem was needed. The solution came in two parts: 1. Qualifying all inspectors to a common set of requirements and issuing a National Board commission to qualified candidates; 2. Authorizing manufacturers to stamp a National Board number on boilers inspected by a National Board Commissioned Inspector.

4 Registration of a boiler with a National Board number could now be completed with the manufacturer submitting an original manufacturer s data report to the National Board for permanent retention. This document, certified by both the manufacturer and the National Board Commissioned Inspector, gave the chief boiler inspectors of all participating states and cities the assurance they needed to allow a boiler to be installed for operation within their respective jurisdictions.

5 In 1924, at the National Board convention held in Cleveland, Ohio, Secretary C.O. Myers (later named the National Board s first executive director) stated the National Board had developed a system of registering and recording ASME boilers, which had become effective July 1, The system was developed to ensure that no state need fear of a counterfeit Code boiler, if it bears the National Board stamp.

6 The foresight of the National Board s founders encouraged boiler sales between multiple states and provided the only central repository for manufacturers data reports.

7 Some changes have occurred over the years, including: 1. The inspectors authorized to engage in new fabrication inspections are commissioned as Authorized Inspectors ; 2. National Board registration was expanded to pressure vessels, piping, and nuclear components as the ASME code grew to include those items; 3. An NB symbol stamp has been implemented for manufacturers to stamp adjacent to the National Board number.

8 These changes have enhanced the basic principles of National Board registration, but the goal is still the same as it was in 1921: provide assurance that a pressure-retaining item was constructed in accordance with the ASME Boiler and Pressure Vessel Code and that it was inspected by a qualified National Board Commissioned Inspector.

9 Today National Board Registration along with ASME Authorizations is generally accepted to allow boilers and pressure vessels to be installed throughout the world. Making these processes truly globally accepted programs.

10 Additional benefits of registration include a method of: 1. Easily obtaining Manufactures Data Reports when need to perform repairs to a vessel. 2. Providing traceability of who takes code responsibility when a pressure retaining item is altered by a National Board R Stamp Holder.

11

12 RStampCertificate of Authorization Program The National Board offers the Certificate of Authorization and R symbol stamp for the repair and/or alteration of boilers, pressure vessels, and other pressureretaining items.

13 NB-415

14 NBIC Part 3, Repairs and Alterations Provides requirements and guidance to perform, verify, and document acceptable repairs or alterations to pressure retaining items regardless of the code of construction.

15 Alternative methods for examination, testing, heat treatment, etc., are provided when the original code of construction requirements cannot be met.

16 Specific acceptable and proven repair methods are also provided for use after a pressure retaining item has been constructed and place in service.

17 For ASME Certificate Holders The review of the applicants quality program and ability to implement the R Stamp program can normally be done in conjunction with the ASME review Or By a manual review by the National Board within 12 months of the ASME review

18 The scope of accreditation is defined in the applicants quality system Can be limited to vessels build by a manufacture or ASME Certificate Holder Or Extended to all types of pressure retaining items

19 NBIC Part 3 is internationally recognized as and acceptable method for performing repairs and alterations & Provides an acceptable method to perform and record repair and alteration activities to maintain code compliance in a method that is acceptable from one jurisdiction to another.

20 Provides requirements that must be met for an organization to obtain a National Board Certificate of Authorization to use the NR Symbol Stamp for repair to nuclear items.

21 Can be used for nuclear items constructed in accordance with the requirements of the ASME Code Or Nuclear items constructed to other recognized international codes or standards for construction or inservice inspection of nuclear facilities.

22 Accreditation requirements are found in NBIC Part 3 and NB- 417, Accreditation of NR Repair Organizations

23 Provides requirements and guidelines for performing repairs to pressure relief valves.

24 Accreditation requirements can be found in NBIC, Part 4 and NB-514, Accreditation of VR Repair Organizations

25 Repair of a pressure relief valve is considered to include the disassembly, replacement, re-machining, or cleaning of any critical part, lapping of a seat and disc, reassembly, testing and any operation that may affect the flow passage, capacity, function, or pressure-retaining integrity of the pressure relief valve.

26 Conversions, changes or adjustments affecting critical parts are also considered repairs. Conversions may include changes in service fluid and changes such as bellows, soft seats, and other changes that may affect Type/Model number.

27 The survey is conducted by a National Board Representative. The scope of accreditation is defined in the applicants quality system.

28 The applicant shall repair and submit for verification testing one valve for each ASME BPV Code section and test fluid that they are seeking accreditation for. A minimum of two valves are required to be submitted regardless of the ASME BPV Code sections or test fluids the organization is seeking accreditation to perform.

29 When a pressure relief valve is repaired, a metal repair nameplate stamped the information required in the NBIC is attached to the valve adjacent to the original manufactures stamping or name plate.

30 This program establishes the requirements for organizations seeking a National Board Certificate of Authorization to use the T/O Certification Mark.

31 Requirements for organizations seeking accreditation for the T/O program are found in NB-528, Accreditation of T/O Test Only Organizations & NBIC Part 2, Paragraph 2.5.7

32 This is a new program that was introduced for organizations wanting to perform only testing of pressure relief valves. Testing is defined as confirming seat tightness and confirming or restoring nameplate set pressure and/or performance (e.g. blowdown, lack of chatter) of pressure relief valves.

33 The T/O Certificate of Authorization does not permit any activity that requires disassembly and/or repair of pressure relief valves. These activities shall be performed by a National Board VR Certificate Holder or the valve shall be replaced.

34 The survey is conducted by a National Board Representative. The implementation demonstration shall include, as a minimum, setting and testing of valves within the scope of the applicant s written Quality Control System.

35 Requires applicant to test and submit to a National Board Accepted Testing Laboratory for verification testing a minimum of two valves. These valves shall include at least one valve for each ASME BPV Code section and each test fluid.

36 Owner-User Inspection Organizations (OUIO) Organizations performing inservice inspection activities of items owned/operated by the organization including inspections of repairs/alterations.

37 This program is designed for organizations who have a large number of pressure retaining items such as: 1. Government Installations 2. Refinery's 3. Power Plants

38 Requirements for organizations seeking the accreditation as an OUIO are found in NB-371, Accreditation of Owner-User Inspection Organizations (OUIO) & NBIC, Parts 1, 2 and 3 NBIC Part 3 is only applicable to organizations also seeking accreditation as an R Certificate of Authorization

39 Applicants must have and maintain a written quality program that meets the requirements of this document and NB-381, Quality Program for Inspection Organizations.

40 Prior to issuance of a Certificate of Accreditation, the OUIO, its written quality program, and its facilities are subject to a review and verification of implementation of its quality program by the National Board. The organization shall fully demonstrate the implementation of the Quality Program.

41 The OUIO shall employ inspectors who meet the requirements of NB-263, RCI-1, Rules for Commissioned Inspectors and who hold a valid National Board Inservice Commission (IS), and an R Endorsement if the scope of inspections include repair/alteration inspections.

42 In addition to the employment of the Inspector(s) the OUIO shall employ one or more supervisors/technical manager(s).

43 The supervisor/technical manager has the overall responsibility for: carrying out inspection activities in accordance with this document; the required duties described in NB-263, RCI-1, Rules for Commissioned Inspectors; and monitoring the performance of the Inspector.

44 The supervisor/technical manager shall also hold a valid National Board Inservice Commission(IS) and an R Endorsement, if the scope of inspections include repair/alteration inspections.
