Watthour Meters Part2

Preface to the Second Edition (1922)
This edition of the Code for Electricity Meters is a revised and complete compilation of the sections issued separately during the past 5 years. The revision and arrangement here have been under the supervision of the Meter Committees of the Association of Edison Illuminating Companies and the National Electric Light Association. Advantage was taken of the printing of the Code in complete form to make such revisions in the text and to add such new matter as appeared desirable. The Electrical Testing Laboratories joined with the Committees in this revision and compilation as they did in the original preparation of the various sections of the Code, and this revised edition has their approval.
The Code for Electricity Meters has been generally accepted as a standard of reference for meter practice. Its revision, completion, and appearance in one volume enhance its value for this purpose.

Preface to the Third Edition (1928)
This edition of the Code for Electricity Meters is a completely revised and rearranged compilation of the Second Edition, issued in 1912, and the section on demand meters, issued in 1920. The 1912-20 edition of the Code was approved as an American Standard by the American Engineering Standards Committee in July 1922 (C12-1922). The present revision has been made under the joint sponsorship of the Association of Edison Illuminating Companies, the National Electric Light Association, and the US National Bureau of Standards by a Sectional Committee representing all interested organizations, in accordance with the procedure established by the American Engineering Standards Committee for the revision of American Standards. The sponsors hereby express their appreciation to the members of the Sectional Committee and their associates for the painstaking and careful manner in which the revision was carried out. A preliminary draft was presented at a meeting of the Sectional Committee on April 1, 1926. This draft was approved in general outline, and referred to an editorial committee consisting of Messrs Brooks, Currier, Doyle, Fellows, Hill, Koenig, Meyer, and Pratt. This committee carefully reviewed the draft, agreed upon a standard form and arrangement, and appointed H. Koenig, the Secretary of the Sectional Committee, to prepare the final draft for the printer. A considerable amount of material appearing in the Second Edition has been omitted, particularly the circuit diagrams in Section VII, all of Section IX, and the maintenance paragraphs of Section X. The sections of chapters have been renumbered. The omitted material is fully covered in the Handbook for Electrical Metermen, where it now properly belongs.ANSI C12.1-2008 This Code, as revised, was submitted in galley-proof form to all the members of the Sectional Committee for final approval by letter ballot, and it was then formally approved by each of the sponsors. The sponsors, acting jointly, presented the Code to the American Engineering Standards Committee for approval as American Standard, and it was so approved February 20, 1928
