FOREWORD

The American Society of Mechanical Engineers set up a

committee in 1911 for the purpose of formulating standard

rules for the construction of steam boilers and other pres-

sure vessels. This committee is now called the Boiler and

Pressure Vessel Committee.

The Committee’s function is to establish rules of safety,

relating only to pressure integrity, governing the construc-

tion 1 of boilers, pressure vessels, transport tanks and

nuclear components, and inservice inspection for pressure

integrity of nuclear components and transport tanks, and

to interpret these rules when questions arise regarding their

intent. This code does not address other safety issues relat-

ing to the construction of boilers, pressure vessels, transport

tanks and nuclear components, and the inservice inspection

of nuclear components and transport tanks. The user of

the Code should refer to other pertinent codes, standards,

laws, regulations, or other relevant documents. With few

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 envi-

ronments. Recognizing this, the Committee has approved

a wide variety of construction rules in this Section to allow

the user or his designee to select those which will provide

a pressure vessel having a margin for deterioration in ser-

vice so as to give a reasonably long, safe period of use-

fulness. Accordingly, it is not intended that this Section

be used as a design handbook; rather, engineering judgment

must be employed in the selection of those sets of Code

rules suitable to any specific service or need.

This Code contains mandatory requirements, specific

prohibitions, and nonmandatory guidance for construction

activities. The Code does not address all aspects of these

activities and those aspects which are not specifically

addressed should not be considered prohibited. The Code

is not a handbook and cannot replace education, experi-

ence, and the use of engineering judgment. The phrase

engineering judgment refers to technical judgments made

by knowledgeable designers 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.

(^1) Construction , as used in this Foreword, is an all-inclusive term com-

prising materials, design, fabrication, examination, inspection, testing, certification, and pressure relief.

vii

The Committee recognizes that tools and techniques

used for design and analysis change as technology prog-

resses 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 comput-

ers 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 they

are responsible for the application of these programs to

their design.

The Code does not fully address tolerances. When

dimensions, sizes, or other parameters are not specified

with tolerances, the values of these parameters are consid-

ered nominal and allowable tolerances or local variances

may be considered acceptable when based on engineering

judgment and standard practices as determined by the

designer.

The Boiler and Pressure Vessel Committee deals with

the care and inspection of boilers and pressure vessels in

service only to the extent of providing suggested rules of

good practice as an aid to owners and their inspectors.

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 Boiler and Pressure Vessel Committee meets regu-

larly to consider revisions of the rules, new rules as dictated

by technological development, Code Cases, and requests

for interpretations. Only the Boiler and Pressure Vessel

Committee has the authority to provide official interpreta-

tions 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 Mandatory Appendix cov-

ering preparation of technical inquiries). Proposed revi-

sions to the Code resulting from inquiries will be presented

to the Main Committee for appropriate action. The action

of the Main Committee becomes effective only after con-

firmation by letter ballot of the Committee and approval

by ASME.

STATEMENT OF POLICY

ON THE USE OF CODE SYMBOLS AND

CODE AUTHORIZATION IN ADVERTISING

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 recogni-

tion of organizations so authorized. An organization hold-

ing 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 Code Symbols

for marking items or constructions that have been con-

structed and inspected in compliance with the ASME Boiler

and Pressure Vessel Code are issued Certificates of Autho-

rization. It is the aim of the Society to maintain the standing

of the Code Symbols for the benefit of the users, the

enforcement jurisdictions, and the holders of the symbols

who comply with all requirements.

Based on these objectives, the following policy has been

established on the usage in advertising of facsimiles of the

symbols, Certificates of Authorization, and reference to

Code construction. The American Society of Mechanical

Engineers does not “approve,” “certify,” “rate,” or

STATEMENT OF POLICY

ON THE USE OF ASME MARKING

TO IDENTIFY MANUFACTURED ITEMS

The ASME Boiler and Pressure Vessel Code provides

rules for the construction of boilers, pressure vessels, and

nuclear components. This includes requirements for mate-

rials, design, fabrication, examination, inspection, and

stamping. Items constructed in accordance with all of the

applicable rules of the Code are identified with the official

Code Symbol Stamp described in the governing Section

of the Code.

Markings such as “ASME,” “ASME Standard,” or any

other marking including “ASME” or the various Code

ix

“endorse” any item, construction, or activity and there shall

be no statements or implications that might so indicate. An

organization holding a Code Symbol and /or a Certificate of

Authorization may state in advertising literature that items,

constructions, or activities “are built (produced or per-

formed) 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.”

The ASME Symbol 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 associa-

tion or a society, or by a holder of a Code Symbol who

may also use the facsimile in advertising to show that

clearly specified items will carry the symbol. General usage

is permitted only when all of a manufacturer’s items are

constructed under the rules.

The ASME logo, which is the cloverleaf with the letters

ASME within, shall not be used by any organization other

than ASME.

Symbols shall not be used on any item that is not con-

structed in accordance with all of the applicable require-

ments 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 excep-

tions to the ASME requirements.
