2 The student will be able to describe: ◦ the history of ASME and the National Board ◦ the history of the National Board Inspection Code ◦ how the NBIC becomes an American National Standard ◦ how the NBIC has changed through the years ◦ the current format of the NBIC 2

3  Industry used waterways for a source of power to run production equipment in the 1700s and early 1800s.  In the 1800s, factories needed to move closer to where raw materials were.  Without waterways, steam became a source of power to operative equipment.  The steam generators/boilers had a tendency to explode, causing up to 50,000 deaths and 2 million injuries annually. 3

4  States and cities establish their own construction rules for their jurisdictions. No national standard existed.  There was no uniformity or interchangeability between states, cities, and counties.  Manufacturers had to satisfy requirements of each jurisdiction in which the boiler was manufactured. Many had none.  Boiler manufacturers and insurance companies asked ASME to develop a single standard in

5  ASME published the first boiler code in  Getting ASME Code adopted by Jurisdictions was a struggle.  The National Board was formed in  National Board formed to unify Jurisdictions and enforcement; provide standardization and interchangeability.  In 1921 The National Board: ◦ Commissioned its first inspector. ◦ Commenced registration of boilers. 5

6 The First NBIC  1945 Chapter I released: Introduction  1946 Chapter II released: Laws and Rules  1946 Chapter III released: Rules for Inspection of Existing Installations of Power Boilers  1946 Chapter IV released: Rules for Inspection of Boilers or Unfired Pressure Vessels  1946 Chapter V released: Rules for Inspection of New Boilers or Pressure Vessels  1947 Chapter VI released: Repairs to Boilers and Pressure Vessels  1949 Chapter VII released: Inspection of Fusion Welding 6

7  1951 First full Edition released Reformatted Chapters  1960 Edition Added: Chapter VIII: low pressure side of reducing valve Chapter IX: low water cut-off and feedwater regulating device Chapter X: inspection and repair PV in service in petroleum refineries 7

8  Continued to address issues of Jurisdiction and Inspectors.  Both shop and inservice.  Based on previously published NB reports and papers. Safety devices, welding, design calculations, nuclear “Truly a manual for boiler and pressure vessel inspectors”  Welding Inspectors qualifications (eyesight, experience, knowledge, training, temperament, agility, physical strength, good judgment, integrity, and honesty.) 8

9  1975 “R” Stamp Program  1977-Owner/User Inspection Agencies, “NR, “VR” Welding requirements deleted ASME Section IX Recognized other codes of construction 1983-American National Standard 9

10  A manual for the Inspector.  Recommended Legislation, Rules and Regulations for Boiler and PV Safety (NB-131, NB-132).  NB members understood problems and difficulties inspectors faced. This provided the basis for developing the NBIC: New designs—increased pressures and temperatures Improved technology—appurtenances, materials, fabrication, etc. 10

11  ANSI is an umbrella organization for standards developed in the USA.  Assures industry input.  Recognized worldwide.  Procedures based on consensus (openness, balance, due process): Public has right to comment All comments must be resolved 11

12  1992-Changes Implemented 5x8 to 8x11 Loose Leaf Annual Addenda – Mandatory 6 months after issue date Reorganized into Sections  1995-Reformatted into Parts Administrative, Inservice Inspection, Repair and Alteration, Repair Methods, Mandatory and Non-mandatory Appendix User friendly 12

13 The 2007 Edition Changes Implemented  Restructured into three parts: Part 1 – Installation Part 2 – Inspection Part 3 – Repairs and Alterations 13

14 The 2011 Edition Changes Implemented  Published in new format (no binders) 14

15 15 JURISDICTION ASME CODE INTERCHANGEABILITY STANDARDIZATION INSPECTOR

16  What is a Jurisdiction? ◦ A government entity with the authority to make laws governing activities within its borders. ◦ Jurisdiction could be a Township, County, City, State, or Province. 16

17  Jurisdictions may have additional requirements in statute or rule. ◦ May require boiler and pressure vessel repairs or alterations to be registered with National Board. ◦ May require the Repair Organization to have jurisdictional license. ◦ May require a Repair Organization to have an “R” stamp. ◦ May have special rules governing routine repairs. ◦ May require an official approval before starting any work. 17

18 18 Click NB Members to locate the jurisdictional authority.
