Development of the Standards
of the
American Institute of Electrical Engineers
Recognizing the importance in the development of electrical engineering, of standardization
in the electrical field, the A. I. E. E. in 1898 appointed a Committee on Standardization, consisting
of seven members having qualifications and experience from designing, manufacturing and operating
standpoints. Th6 report of this Committee was accepted at a meeting of the Institute in June
1899.
Experience gained in applications of the standards and further developments in electrical
apparatus and methods showed the necessity of revision, and a committee was appointed which
after consultation with manufacturing and operating engineers presented the first revised report
on Standardization Rules of the A. I. E. E. in June 1902.
The next revision was undertaken by a committee of ten, which presented its report in May
1906.
In September 1906, a Standards Committee of eleven members was appointed for further
revision, and its report was presented in June 1907.
The appreciation of the importance and value of standardization resulted in the formation of
a Standing Committee, with the title of Standards Committee of the A. I. E. E. This became
effective in the Constitution of June 1907. The scope and amount of work necessitated increasing
the number of members from time to time until in 1922 there were 37 members divided into a
number of subcommittees specializing on various subjects.
A. I. E. E. Standards published in a single volume as each revision was adopted have been
generally accepted as Standards of the electrical industry of the United States since the adoption
of the first report in 1899. Subsequent reports on Standards were made and published in some
cases in several editions. The dates of adoption by the Board of Directors of such reports are as
follows: June 20, 1902; June 21, 1907; June 27, 1911; July 10, 1914; June 30, 1915; June 28, 1916;
November 8, 1918; October 8, 1920, and June 29, 1922.
On June 29, 1922, in view of the increasing complexity of the work, a reorganization of the
Standards Committee was effected, and a working organization established which provided for an
increase in standardization work and for the appointment on Working Committees of the Standards
Committee of non-Institute members.
The present plan under which the Institute Standards are being issued involves the separation
of the complete body of Standards into more than forty sections, each published as a separate
pamphlet and dealing with a specific subject. Each section of the Standards has been formulated
either by a Working Committee of the Standards Committee which has been made as representa-
tive as possible for the work in hand or by a Sectional Committee organized according to the proce-
dure of the American Standards Association. The division of the Standards into a number of sepa-
rate publications simplifies the process of keeping the Standards revised to conform with the latest
developments and enables those interested in a particular field to obtain in concise form the material
relating to that field. In framing the Institute Standards the chief purpose has been to define terms
and conditions which characterize the rating and behavior of electrical machinery and apparatus,
with special reference to the conditions of acceptance tests.
The Standards Committee takes this occasion to draw attention to the value of suggestions
based upon experience gained in the application of the Standards to general practise. Any sugges-
tions looking toward improvement in the Standards will be welcomed for the guidance of the Com-
mittee in preparation of future editions, and should be communicated to the Secretary of the
A. I. E. E. Standards Committee, 33 West 39th Street, New York.

ACKNOWLEDGMENT
The Institute wishes to acknowledge its indebtedness to those who
have so freely given their time and knowledge and have conducted ex-
perimental work on which many of the A. I. E. E. Standards are based.
