In 1911, The American Society of Mechanical Engineers established the Boiler and Pressure Vessel Committee to formulate standard rules for the construction of steam boilers and other pressure vessels. In 2009, the Boiler and Pressure
Vessel Committee was superseded by the following committees:
(a) Committee on Power Boilers (I)
(b) Committee on Materials (II)
(c) Committee on Construction of Nuclear Facility Components (III)
(d) Committee on Heating Boilers (IV)
(e) Committee on Nondestructive Examination (V)
(f) Committee on Pressure Vessels (VIII)
(g) Committee on Welding, Brazing, and Fusing (IX)
(h) Committee on Fiber-Reinforced Plastic Pressure Vessels (X)
(i) Committee on Nuclear Inservice Inspection (XI)
(j) Committee on Transport Tanks (XII)
(k) Technical Oversight Management Committee (TOMC)
Where reference is made to “the Committee” in this Foreword, each of these committees is included individually and
collectively.
The Committee’s function is to establish rules of safety relating only to pressure integrity, which govern the
construction** of boilers, pressure vessels, transport tanks, and nuclear components, and the inservice inspection of nuclear components and transport tanks. The Committee also interprets these rules when questions arise regarding their
intent. The technical consistency of the Sections of the Code and coordination of standards development activities of the
Committees is supported and guided by the Technical Oversight Management Committee. This Code does not address
other safety issues relating to the construction of boilers, pressure vessels, transport tanks, or nuclear components, or
the inservice inspection of nuclear components or transport tanks. Users of the Code should refer to the pertinent codes,
standards, laws, regulations, or other relevant documents for safety issues other than those relating to pressure integrity. Except for Sections XI and XII, and with a few other exceptions, the rules do not, of practical necessity, reflect the
likelihood and consequences of deterioration in service related to specific service fluids or external operating environments. In formulating the rules, the Committee considers the needs of users, manufacturers, and inspectors of pressure
vessels. The objective of the rules is to afford reasonably certain protection of life and property, and to provide a margin
for deterioration in service to give a reasonably long, safe period of usefulness. Advancements in design and materials
and evidence of experience have been recognized.
This Code contains mandatory requirements, specific prohibitions, and nonmandatory guidance for construction activities and inservice inspection and testing activities. The Code does not address all aspects of these activities and those

aspects that are not specifically addressed should not be considered prohibited. The Code is not a handbook and cannot
replace education, experience, and the use of engineering judgment. The phrase engineering judgement refers to technical judgments made by knowledgeable engineers experienced in the application of the Code. Engineering judgments
must be consistent with Code philosophy, and such judgments must never be used to overrule mandatory requirements
or specific prohibitions of the Code.
The Committee recognizes that tools and techniques used for design and analysis change as technology progresses
and expects engineers to use good judgment in the application of these tools. The designer is responsible for complying
with Code rules and demonstrating compliance with Code equations when such equations are mandatory. The Code
neither requires nor prohibits the use of computers for the design or analysis of components constructed to the

requirements of the Code. However, designers and engineers using computer programs for design or analysis are cautioned that they are responsible for all technical assumptions inherent in the programs they use and the application of
these programs to their design.
The rules established by the Committee are not to be interpreted as approving, recommending, or endorsing any proprietary or specific design, or as limiting in any way the manufacturer's freedom to choose any method of design or any
form of construction that conforms to the Code rules.
The Committee meets regularly to consider revisions of the rules, new rules as dictated by technological development,
Code Cases, and requests for interpretations. Only the Committee has the authority to provide official interpretations of

this Code. Requests for revisions, new rules, Code Cases, or interpretations shall be addressed to the Secretary in writing
and shall give full particulars in order to receive consideration and action (see Submittal of Technical Inquiries to the
Boiler and Pressure Vessel Standards Committees). Proposed revisions to the Code resulting from inquiries will be presented to the Committee for appropriate action. The action of the Committee becomes effective only after confirmation
by ballot of the Committee and approval by ASME. Proposed revisions to the Code approved by the Committee are submitted to the American National Standards Institute (ANSI) and published at to
invite comments from all interested persons. After public review and final approval by ASME, revisions are published at
regular intervals in Editions of the Code.
The Committee does not rule on whether a component shall or shall not be constructed to the provisions of the Code.
The scope of each Section has been established to identify the components and parameters considered by the Committee
in formulating the Code rules.
Questions or issues regarding compliance of a specific component with the Code rules are to be directed to the ASME
Certificate Holder (Manufacturer). Inquiries concerning the interpretation of the Code are to be directed to the Committee. ASME is to be notified should questions arise concerning improper use of an ASME Certification Mark.
When required by context in this Section, the singular shall be interpreted as the plural, and vice versa, and the feminine, masculine, or neuter gender shall be treated as such other gender as appropriate.

ASME has established procedures to authorize qualified organizations to perform various activities in accordance
with the requirements of the ASME Boiler and Pressure Vessel Code. It is the aim of the Society to provide recognition
of organizations so authorized. An organization holding authorization to perform various activities in accordance with
the requirements of the Code may state this capability in its advertising literature.
Organizations that are authorized to use the Certification Mark for marking items or constructions that have been
constructed and inspected in compliance with the ASME Boiler and Pressure Vessel Code are issued Certificates of
Authorization. It is the aim of the Society to maintain the standing of the Certification Mark for the benefit of the users,
the enforcement jurisdictions, and the holders of the Certification Mark who comply with all requirements.
Based on these objectives, the following policy has been established on the usage in advertising of facsimiles of the
Certification Mark, Certificates of Authorization, and reference to Code construction. The American Society of Mechanical
Engineers does not “approve,” “certify,” “rate,” or “endorse” any item, construction, or activity and there shall be no statements or implications that might so indicate. An organization holding the Certification Mark and/or a Certificate of
Authorization may state in advertising literature that items, constructions, or activities “are built (produced or performed) or activities conducted in accordance with the requirements of the ASME Boiler and Pressure Vessel Code,”
or “meet the requirements of the ASME Boiler and Pressure Vessel Code.” An ASME corporate logo shall not be used
by any organization other than ASME.

The Certification Mark shall be used only for stamping and nameplates as specifically provided in the Code. However,
facsimiles may be used for the purpose of fostering the use of such construction. Such usage may be by an association or
a society, or by a holder of the Certification Mark who may also use the facsimile in advertising to show that clearly specified items will carry the Certification Mark. General usage is permitted only when all of a manufacturer’s items are
constructed under the rules.

The ASME Boiler and Pressure Vessel Code provides rules for the construction of boilers, pressure vessels, and nuclear
components. This includes requirements for materials, design, fabrication, examination, inspection, and stamping. Items
constructed in accordance with all of the applicable rules of the Code are identified with the official Certification Mark
described in the governing Section of the Code.
Markings such as “ASME,” “ASME Standard,” or any other marking including “ASME” or the Certification Mark shall not
be used on any item that is not constructed in accordance with all of the applicable requirements of the Code.
Items shall not be described on ASME Data Report Forms nor on similar forms referring to ASME that tend to imply
that all Code requirements have been met when, in fact, they have not been. Data Report Forms covering items not fully
complying with ASME requirements should not refer to ASME or they should clearly identify all exceptions to the ASME
requirements.

INTRODUCTION

(a) The following information provides guidance to Code users for submitting technical inquiries to the committees.
See Guideline on the Approval of New Materials Under the ASME Boiler and Pressure Vessel Code in Section II, Parts C
and D for additional requirements for requests involving adding new materials to the Code. Technical inquiries include
requests for revisions or additions to the Code rules, requests for Code Cases, and requests for Code Interpretations, as
described below.
(1) Code Revisions. Code revisions are considered to accommodate technological developments, address administrative requirements, incorporate Code Cases, or to clarify Code intent.
(2) Code Cases. Code Cases represent alternatives or additions to existing Code rules. Code Cases are written as a
question and reply, and are usually intended to be incorporated into the Code at a later date. When used, Code Cases
prescribe mandatory requirements in the same sense as the text of the Code. However, users are cautioned that not
all jurisdictions or owners automatically accept Code Cases. The most common applications for Code Cases are:
(-a) to permit early implementation of an approved Code revision based on an urgent need
(-b) to permit the use of a new material for Code construction
(-c) to gain experience with new materials or alternative rules prior to incorporation directly into the Code
(3) Code Interpretations. Code Interpretations provide clarification of the meaning of existing rules in the Code, and
are also presented in question and reply format. Interpretations do not introduce new requirements. In cases where
existing Code text does not fully convey the meaning that was intended, and revision of the rules is required to support
an interpretation, an Intent Interpretation will be issued and the Code will be revised.

(c) Inquiries that do not comply with these provisions or that do not provide sufficient information for a committee’s
full understanding may result in the request being returned to the inquirer with no action.

2

INQUIRY FORMAT
Submittals to a committee shall include:
(a) Purpose. Specify one of the following:
(1) revision of present Code rules
(2) new or additional Code rules
(3) Code Case
(4) Code Interpretation

(b) Background. Provide the information needed for the committee’s understanding of the inquiry, being sure to include reference to the applicable Code Section, Division, edition, addenda (if applicable), paragraphs, figures, and tables.
Preferably, provide a copy of the specific referenced portions of the Code.
(c) Presentations. The inquirer may desire or be asked to attend a meeting of the committee to make a formal presentation or to answer questions from the committee members with regard to the inquiry. Attendance at a committee meeting shall be at the expense of the inquirer. The inquirer’s attendance or lack of attendance at a meeting shall not be a
basis for acceptance or rejection of the inquiry by the committee.
