It contains appendices which cover approval of new material, methods of checking safety valve, safety relief
valve capacity, definitions relating to boiler design and welding and quality control systems.
SECTION V – Nondestructive Examination:
This section describes for Requirements and methods for nondestructive examination which are referenced and required by other code Sections. It also includes manufacturer’s examination responsibilities, duties of authorized inspectors and requirements for qualification of personnel, inspection and examination.
SECTION VI – Recommended Rules for the Care and Operation of Heating Boilers:
It defines general descriptions, terminology and guidelines applicable to steel and cast iron boilers limited
to the operating ranges of Section IV Heating Boilers. It includes guidelines for associated controls and
automatic fuel burning equipment.
SECTION VII – Recommended Guidelines for the Care of Power Boilers:
This section describes Guidelines to promote safety in the use of stationary, portable, and traction type heating boilers. The section provides guidelines to assist operators of power boilers in maintaining their plants as safely as possible. Contains fuels for routine operation; Operating and maintaining boiler appliances; Inspection and
prevention of boiler failure; Design of installation; Operation of boiler auxiliaries; Control of internal chemical
conditions.
SECTION VIII – Pressure Vessels:
This Section Provides all Rules and requirements applicable to the design, fabrication, inspection, testing, and certification of pressure vessels. It has following Divisions.
Division 1
This Division Provides requirements applicable to the design, fabrication, inspection, testing, and certification
of pressure vessels operating at either internal or external pressures exceeding 15 psig.
Division 2
This Division Provides Alternative rules, provides requirements to the design, fabrication, inspection, testing, and
certification of pressure vessels operating at either internal or external pressures exceeding 15 psig.
Division 3
This Division Provides Alternative rules for Construction of High Pressure Vessels, provides requirements applicable
to the design, fabrication, inspection, testing, and certification of pressure vessels operating at either
internal or external pressures generally above 10,000 psi.
SECTION IX – Welding and Brazing Qualifications:
This section provides Rules relating to the qualification of welding and brazing procedures as required by other Code Sections for component manufacture. Covers rules are related to the qualification and re-qualification of welders
and welding and brazing operators in order that they may perform welding or brazing as required by other
Code Sections in the manufacture of components.
SECTION X – Fiber-Reinforced Plastic Pressure Vessels:
This section provides Requirements for construction of FRP (Fiber-Reinforced Plastic) pressure vessels in conformance with
a manufacturer’s design report. It includes production, processing, fabrication, inspection and testing
methods required.
SECTION XI – Rules for In-service Inspection of Nuclear Power Plant Components:
This section provides Requirements for the examination, in-service testing and inspection, and repair and replacement of components and systems in light-water cooled and liquid-metal cooled nuclear power plants.
SECTION XII – Rules for Construction and Continued Service of Transport Tanks:
This section provides Requirements for construction and continued service of pressure vessels for the transportation of dangerous goods via highway, rail, air or water at pressures from full vacuum to 3,000 psig and volumes
greater than 120 gallons.
