Rules pertaining to use of the single ASME certification mark with the H, HV, and HLW designators are also included.
..Is another “service Code” – containing requirements and methods for nondestructive examination which are referenced and required by other BPVC Sections. It also includes manufacturer’s examination responsibilities, duties of authorized inspectors and requirements for qualification of personnel, inspection and examination. Examination methods are intended to detect surface and internal discontinuities in materials, welds, and fabricated parts and components. A glossary of related terms is included.
Recommended Rules for the Care and Operation of Heating Boilers （加熱ボイラの保守及び運転に関する推奨規則）
Covers operation guidelines applicable to steel and cast-iron boilers limited to the operating ranges of Section IV Heating Boilers. Section VI includes guidelines for associated controls and automatic fuel-burning equipment. Also included is a glossary of terms commonly associated with boilers, controls, and fuel-burning equipment.
Recommended Guidelines for the Care of Power Boilers （動力ボイラの保守に関する推奨規則）
Provides guidelines to assist those directly responsible for operating, maintaining, and inspecting power boilers. These boilers include stationary, portable, and traction type boilers, but not locomotive and high-temperature water boilers, nuclear power-plant boilers (see Section XI), heating boilers (see Section VI), pressure vessels, or marine boilers. Guidelines are also provided for operation of auxiliary equipment and appliances that affect the safe and reliable operation of power boilers.
Rules for Construction of Pressure Vessels （圧力容器建造基準）
Division 1 provides requirements applicable to the design, fabrication, inspection, testing, and certification of pressure vessels operating at either internal or external pressures exceeding 15 psig. Such vessels may be fired or unfired. This pressure may be obtained from an external source or by the application of heat from a direct or indirect source, or any combination thereof. Specific requirements apply to several classes of material used in pressure vessel construction, and also to fabrication methods such as welding, forging and brazing.
Division 1 contains mandatory and non-mandatory appendices detailing supplementary design criteria, nondestructive examination and inspection acceptance standards. Rules pertaining to the use of the single ASME certification mark with the U, UM and UV designators are also included.
Alternative Rules （代替規制） Division 2 requirements on materials, design, and nondestructive examination are more rigorous than in Division 1; however, higher design stress intensity values are permitted. These rules may also apply to human occupancy pressure vessels typically in the diving industry. Rules pertaining to the use of the single ASME certification mark with the U2 and UV designators are also included.
Alternative Rules for Construction of High Pressure Vessels （高圧力容器建造の代替規制） Division 3 requirements are applicable to pressure vessels operating at either internal or external pressures generally above 10,000 psi.

Starting with this 2015 Edition, the BPVC will be revised every two years. But what happens in the interim with new materials or alternative constructions? How does the BPVC keep current with the latest in technology and applications? Code Cases are approved actions by the BPVC Committees on these alternatives, intended to allow early and urgent implementation of any revised requirements. They are issued four times per year in two categories: Boiler and Pressure Vessels (CC-BPV) and Nuclear (CC-NUC). Users may purchase individual publications at any time. Or they may subscribe to receive full sets of Code Cases as they are published for the duration of that BPVC edition’s cycle. This responsiveness to requests illustrates the unique openness and transparency of ASME’s code-development process – striving to reflect best-practices of industry, while contributing to safety for the general public.
