Harmonized Requirements for Historical Boilersregulatory authority (see reference to inspection in the Maintenance sectionbelow). Each regulatory authority identified in this document may have additionalrequirements. For these additional requirements, refer to the appropriatesupplement included in this document.The operator of a historical boiler shall hold the appropriate valid certificate(license, certificate of qualification, certificate of competency, etc.) issued by thejurisdiction where the historical boiler will be operated. See the appropriatesupplement for the requirements of the jurisdiction.Training records and an operating logbook shall be maintained to show how theoperator has been trained and assessed as competent.Valid operating permits/licenses may be accepted for transfer by the provincesreferenced in this document providing requirements of the general section of thisdocument are met. The destined operating province may have additionalrequirements which are detailed in the provincial supplement section of thisdocument.4.5Inspection and MaintenanceAs part of the ongoing maintenance of a historical boiler, the owner must conductperiodic internal and external inspections to ensure the boiler is safe to operateand in good working condition. When not in service, historical boilers must bestored in a manner that prevents unintentional damage (corrosion, freezing etc.).Additionally, historical boilers shall be subject to annual inspections by aninspector holding a National Board In-service Commission and employed by aregulatory authority. The inspection shall conform to CSA B51-19, NBIC 2019Part 2 Supplement 2 and the specific requirements of the regulatory authoritywhere the boiler is located.Each historical boiler shall be hydrostatically pressure tested in accordance withNBIC S2.6.1 every three years and the test shall be witnessed by the regulatoryauthority. The test pressure shall be no less than 1.25x the calculated MAWP fora minimum of 10 minutes or until a complete inspection can be made. At the timeof the test, the water and boiler metal temperature shall be between 16ºC and49ºC. Dial pressure gauges used in testing should have a range of approximatelydouble the intended maximum test pressure, but in no case shall the range beless than 1½ nor more than 4 times that pressure. The test gauge must be ingood working order and its accuracy should be verified periodically throughcalibration*. The owner shall ensure that any pressure tests are conductedsafely.*Note: Calibrations should be traceable to a national measurement standard.Issued 2020-08-19AB-534 Edition 2, Revision 0Page 5 of 23

Harmonized Requirements for Historical BoilersRepairs and alterations to historical boilers shall be performed by the holder of aquality control program that defines in its scope the repairs to ASME Section Iboilers. This quality control program shall be current and the certificate ofauthorization shall be issued by the regulatory authority where the repair oralteration will occur. The regulatory authority may accept repairs performed bythe holder of a National Board “R” stamp program.All repairs and alterations shall be approved by the regulatory authority beforework commences. Changes in the boiler condition might justify recalculation ofthe MAWP in accordance with the method provided in CSA B51-19 Annex I,Clause I.2 and shall be treated as an alteration if recalculated to a different value(See Annex I, Clause I.9).An inspector, holding the National Board “R” endorsement, and employed by theregulatory authority where the repair or alteration will occur, shall be involvedthroughout the duration of the repair or alteration and shall inspect and certify therepair or alteration on the appropriate form(s) once the work is completed.4.6Safety ValvesSafety valve(s) shall be serviced at a minimum every five years by the holder of acertificate of authorization for the servicing of Section I (“V” stamped and “NB”capacity certified) safety valves.The owner shall ensure that a function test of the safety valve is conducted safelyat every initial steaming of the historical boiler each season or when the boilerhas been laid up for an extended period of time. The function test isaccomplished by having the operator slowly raise the pressure up to the boilerMAWP causing the safety valve to open.4.7Fusible PlugsThe fusible plug is to be inspected annually for deterioration. The threads wherethe plug is inserted shall be inspected for corrosion. The fusible plug operatinghours shall be recorded in the owner’s logbook.Fusible plugs shall be replaced after 500 hours of operation. If operating hourscannot be validated the fusible plug shall be replaced every 3 years as per NBICS2.8.4. Fusible plug life shall not exceed ten calendar years and leaking fusibleplugs shall be replaced.4.8DecommissioningHistorical boilers that are decommissioned because they are no longer fit forservice should be left in a condition to ensure they cannot be pressurized. Theregulatory authority must to be notified of any historical boiler that has beendecommissioned.Issued 2020-08-19AB-534 Edition 2, Revision 0Page 6 of 23

Harmonized Requirements for Historical Boilers5.0 ADDITIONAL INSPECTION REQUIREMENTS5.1NDE RequirementsNDE inspections, as described in NBIC 2019 for initial testing are to beperformed at the initial inspection and repeated every five years.NDE technicians shall be CGSB level 2 or SNT level 2 and familiar with theinspection of historical boilers.A detailed map of where readings are taken shall be maintained so that readinglocations may be repeated.Straight beam ultrasonic testing (UT) of all shell areas without stays shall betaken at a maximum grid pattern of 12 inches. Additional readings shall be takenif conditions warrants or in areas where thinning is suspected. Concerning stayedsections, the plate thickness readings shall be taken on a grid not exceeding themaximum staybolt pitch. Additional readings may be taken close to each stayboltto determine if localized thinning has occurred.Straight beam UT of tube sheets and the dome shell shall be taken in a 6 inchgrid pattern.Close attention must be given to rivets which are showing signs of weakening.This will be evident from leakage especially during the hydrotest. NBIC S2.10.2.2shall be used as guidance to inspect corroded rivets.Perform straight beam UT of 100% of the firebox stays. Radial stays shall bevisually examined from the rear hand hole or by using a borescope.Shear wave UT and magnetic particle inspection (MPI) 100% of the lap andbuttstrap longitudinal seams in the shell and the dome to validate no shell platecracking. MPI must also be performed of all areas susceptible to cracking suchas knuckles and Ogee joints. Due to the ability to inspect the lap and butt-straplong seams of the shell and the dome using UT techniques there is no longer aneed for slotting of riveted joints nor is it advisable.UT thickness readings of the various components are to be used to calculate theMAWP following the process described in CSA B51-19 Annex I and NBIC 2019S2.10.Issued 2020-08-19AB-534 Edition 2, Revision 0Page 7 of 23

Harmonized Requirements for Historical Boilers6.0 INTER-PROVINCIAL MOBILITY OF HISTORICAL BOILERS6.1Initial Inspection of Existing EquipmentHistorical boiler owners wishing to operate their historical boiler in anotherprovince shall satisfy all the requirements of the destination province. Refer tothe appropriate supplement for the details of these requirements.Owners should be prepared to present UT surveys and NDE records, calculationof the MAWP of the boiler, inspection records signed by the National Boardcommissioned inspector employed by the regulatory authority in the homeprovince. The acceptable inspection standards are CSA B51-19 and NBIC 2019Part 2 supplement 2 (the inspection for historical boilers).The owner shall have copies of the certification of the safety valve(s) showingthat the safety valve(s) was serviced and tested in the last five years and alogbook documenting any function test(s) performed. The owner shall also havecalibration records for the main pressure gauge showing re-certification within thecurrent year.6.2Operator CertificationThe historical boiler operator shall hold a valid certificate or license to operateissued by the local authority where the historical boiler will be operated. Refer tothe appropriate supplement for details on how to obtain this certification. Theowner shall also have training and assessment records of each operator showinghow the operator was deemed competent to operate the historical boiler.6.3Validation of IntegrityThe regulatory authority, where the historical boiler is intended to be operated,shall be notified a minimum of three weeks prior to the intent to operate thehistorical boiler. This will allow the local inspector time to review inspectionrecords and to schedule any additional inspections required. Any outstandinginspection issues identified from the originating regulatory authority shall becleared prior to operation in another province.Once the historical boiler arrives in the destination jurisdiction, the jurisdictionalinspector will perform an external inspection ensuring that no damage occurredduring transportation.The operator shall be requested to conduct a function test by slowly bringing thepressure up to the accepted MAWP causing the safety valve to open. This actiondemonstrates the boiler is sound for operation and validates that the safety valvewill function and protect the boiler at its MAWP.Issued 2020-08-19AB-534 Edition 2, Revision 0Page 8 of 23
