(13) ASME FOREWORD

The first edition of this Code was published in January 1921. It was prepared by an American Society of Mechanical Engineers (ASME) Committee on Protection of Industrial Workers with the assistance of representatives of a number of interests including manu-facturers, insurance carriers, regulatory bodies, and technical societies.

Subsequently, ASME requested the American Engineering Standards Committee (AESC) to authorize the organization of a Sectional Committee to undertake this revision. They acted favorably on this request, and in January 1922, assigned sponsorship for the project jointly to the American Institute of Architects, the National Bureau of Standards, and ASME, all three of whom had taken an active part in the preparation of the first edition of the Code.

The organization meeting of the Sectional Committee A17 was held in November 1922. A number of meetings of the Committee were held during the next two years and in July 1925, a revision of the 1921 Code was com-pleted, approved by the AESC, and published as an American Standard.

Subsequent to the publication of the 1925 revision of the Code, the necessity for development research on the design and construction of car safeties and oil buffers and for the development of test specifications for various parts of elevator equipment was realized.

As a result, a Subcommittee on Research, Recommendations, and Interpretations was appointed in 1926. This subcommittee held regular meetings there-after until interrupted by the war in 1940, and carried on an extensive test program at the National Bureau of Standards in connection with oil buffers and car safeties.

Subsequent to the war, the name of this subcommittee was changed to “Executive Committee for the Elevator Safety Code.”

The information gained as a result of these tests, together with the developments that had occurred in the design of the equipment as a result of installations made in very tall buildings, prompted the Sectional Committee to prepare and issue the third edition of the Code in 1931. The third edition was approved by the Sectional Committee in February 1931, and subse-quently by the sponsors and by the American Standards Association (formerly the AESC) in July 1931.

Further experience and developments in the design of elevator equipment, led the Sectional Committee, in line with its policy of revising the Code periodically, to prepare the fourth edition in 1937, which was approved viii by the sponsors and by the American Standards Association (ASA) in July 1937.

A fifth edition of the Code was well under way in 1940 when it was necessary to suspend the work due to the Second World War. However, a number of the revisions already agreed upon by the Sectional Committee and approved by the sponsors and by the ASA in April 1942, were issued as a supplement to the 1937 edition. They were subsequently incorporated in a reprint of the 1937 edition in 1945. In response to public demand, requirements for private residence elevators were also issued in a separate supplement, ASA A17.1.5-1953, and incorporated into the Code as Part V in the 1955 edition.

The Sectional Committee reinitiated consideration of the fifth edition of the Code in 1946. Due to the consider-able period which had elapsed since the fourth revision in 1937, and to the very extensive developments in the elevator art, the committee decided that the Code should be completely rewritten and brought up to date.

Special subcommittees were appointed to prepare the revisions of the various requirements. The membership of each subcommittee consisted of persons especially familiar with the requirements to be covered by that subcommittee. Fifteen subcommittees were set up with a total membership of over 150 persons. The member-ship of these subcommittees was not confined to mem-bers of the Sectional Committee. It also included other persons having expert knowledge of the subjects under consideration by the subcommittees. These subcommit-tees and their personnel were listed in the 1955 edition of the Code.

The drafts prepared by these subcommittees were widely circulated to interested groups for comment.

After review of the comments and correlation of the drafts, the fifth edition of the Code was approved by the Sectional Committee, subsequently by the sponsors, and by the ASA in June 1955.

In December 1957, a Supplement to the Code listing a number of revisions was approved by the ASA and published by ASME.

A sixth edition was published in 1960 which incorpo-rated the revisions contained in the 1957 Supplement as well as approximately 96 revisions which were approved by the Sectional Committee in March 1960.

In 1958 the scope of the A17 Code was enlarged to include moving walks. The membership of the Sectional Committee was expanded to include manufacturers whose primary interest in the Committee was the devel-opment of rules and regulations on moving walks. A

subcommittee prepared a Safety Code for Moving Walks which was approved by the Sectional Committee, the sponsors, and by the ASA on March 20, 1962. This Code was published as Part XIII of the A17.1 Code, and was designated ASA A17.1.13-1962.

During 1962 and 1963, 38 additional changes to Parts I through XII of A17.1 were approved by the Sectional Committee, the sponsors, and the ASA, and were pub-lished as the 1963 Supplement to the 1960 edition of the Code.

A seventh edition was published in 1965 which incor-porated the rules of the Safety Code for Moving Walks, ASA A17.1.13-1962, as Part XIII, the revisions covered by the 1963 Supplement as well as approximately 90 other revisions approved by the Sectional Committee, the sponsors, and the ASA. The title of the Code was also changed to the American Standard Safety Code for Elevators, Dumbwaiters, Escalators, and Moving Walks.

On August 24, 1966, the American Standards Association was reconstituted as the United States of America Standards Institute. The designation of stan-dards approved as American Standards was changed to USA Standards. There was no change in the index identification or the technical content of the standards.

At the same time, the ASA Sectional Committee, A17 on A Safety Code for Elevators, was changed to the USA Standards Committee, A17 on A Safety Code for Elevators. Four supplements to this edition were pub-lished from 1967 through 1970.

The United States of America Standards Institute later changed its name to American National Standards Institute, Incorporated (ANSI) on October 6, 1969. At the time that the new name became effective, the desig-nation USA Standard was changed to American National Standard and the name of committees changed from USA Standards Committees to American National Standards Committees. The alphabetical designation of standard documents was changed from USA to ANSI.

The eighth edition of the Code (1971) incorporated the revisions covered by the four supplements and an additional 94 revisions. Seven supplements were issued from 1972 through 1976. Part XIV covering Material Lifts and Dumbwaiters with Automatic Transfer Devices was added in supplement ANSI A17.1d-1975.

The ninth edition of the Code (1978) incorporated 75 revisions in addition to those covered by the previous supplements. Part XV covering Special Purpose Personnel Elevators was added and the Reference Codes, Standards, and Specifications were moved from the Preface to a new Part XVI. Two supplements to this edition were issued in 1979 and 1980.

The tenth edition of the Code (1981) incorporated the revisions covered by Supplements ANSI A17.1a-1979 and ANSI A17.1b-1980, as well as the following new material: Part XVII, Inclined Elevators; Appendix F, Seismic Regulations; and Appendix G, Recommended ix

Practice for Accelerating Moving Walks. Rule 211.3 and Part V were also completely revised, with the Private Residence Inclined Lifts moved to Part XVIII. Numerous other revisions and additions were also included which were approved since the time of the 1980 supplement.

The tenth edition of the Code was approved by the A17 Standards Committee. Since that time, the commit-tee was reorganized in accordance with the ANSI Accredited Organization Method under the sponsorship of ASME. With this reorganization, the National Bureau of Standards and the American Institute of Architects relinquished their roles as cosecretariats. The Standards, Conference, and Executive Committees were also restructured as the Main Committee and the National Interest Review Committee, with the Working Committees (subcommittees) continuing to operate as before.

This reorganization also prompted a change in the title of the Code to the ANSI/ASME A17.1 Safety Code for Elevators and Escalators. The title was also shortened for convenience, and it should not be construed that the Code no longer covers dumbwaiters, moving walks, or the other equipment included within the Scope of the Code.

Two supplements to the 1981 edition were issued:

ANSI/ASME A17.1a-1982 and ANSI/ASME A17.1b-1983. The 1982 supplement included a new Part XIX covering Elevators Used for Construction. In the 1983 supplement, the requirements for Private Residence Inclined Lifts in Part XVIII were expanded and incorpo-rated into a new Part XXI covering Private Residence Inclined Stairway Chairlifts and Inclined and Vertical Wheelchair Lifts. Part XX was added to cover these same devices installed in buildings other than private resi-dences. Requirements for Screw Column Elevators were also added and designated as Part XVIII.

The eleventh edition of the Code (1984) incorporated the changes made in the 1982 and 1983 supplements, as well as additional revisions.

The eleventh edition was updated with five supple-ments which were issued approximately every 6 months in 1985 through the spring of 1987. Appendix I (since redesignated as Appendix E) was added in ANSI/ASME A17.1a-1985. Requirements for rack and pinion elevators were added in ANSI/ASME A17.1c-1986, designated as Part XVI. The previous Part XVI (Reference Codes, Standards, and Specifications) was moved to Section 4 of the Introduction. In ANSI/ASME A17.1d-1986, the requirements for side-walk elevators in Part IV, and alterations in Part XII, were completely revised.

The twelfth edition of the Code incorporated the changes made in supplements A17.1a-1985 through A17.1e-1987, as well as additional revisions. Among these changes was a complete revision of the require-ments for dumbwaiters in Part VII. The format of the

Code was also changed editorially to incorporate Exceptions into the body of the Rules.

The thirteenth edition of the Code incorporated the changes made in A17.1a-1988 and A17.1b-1989 as well as additional revisions. Part XXII, Shipboard Elevators, was added in A17.1b-1989. Part XXIII, Rooftop Elevators, appeared for the first time in this edition.

The fourteenth edition of the Code incorporates the changes made in A17.1a-1991 and A17.1b-1992 as well as the revisions shown in the Summary of Changes.

Safety requirements for seismic risk zone 3 and greater were moved from Appendix F into new Part XXIV, Elevator Safety Requirements for Seismic Risk Zone 2 or Greater. Requirements for seismic risk zone 2 were added to Part XXIV.

The fifteenth edition of the Code incorporates the changes made in A17.1a-1994 and A17.1b-1995 as well as the revisions shown in the Summary of Changes.

Part XXV, Limited Use/Limited Application Elevators, was added in A17.1b-1995. The rules in Part III have been harmonized with the CAN/CSA B44, Elevator Safety Standard, Sections 4 and 11, and Appendix G4.

The sixteenth edition of the Code incorporates changes made in A17.1a-1997 through A17.1d-2000.

Requirements for Mine Elevators have also been added in Section 5.9 of this edition. In addition, the entire Code was reformatted to incorporate a decimal numbering system. For this edition of the Code cross-reference tables have been provided in order to facilitate the corre-lation between requirements from the fifteenth edition of the Code to the renumbered requirements of the six-teenth edition and vice versa. It is also noted, that this edition of A17.1 was the result of a joint effort between the ASME A17 Elevator and Escalator Committee and the CSA B44 Technical Committee to harmonize require-ments between the ASME A17.1, Safety Code for Elevators and Escalators, and the CSA B44, Safety Code for Elevators.

The seventeenth edition of the Code incorporates changes made in A17.1a-2002 and A17.1b-2003. Addi-tionally, in Sections 8.10 and 8.11, cross-references have been updated to reflect ASME A17.2-2001, Guide for Inspection of Elevators, Escalators, and Moving Walks.

The eighteenth edition of the Code is a fully bi-national standard. All former deviations between the ASME A17.1 Code and the CSA B44 Code have been fully addressed within this one Code. Additionally, this edition incorporates revisions to address the advance-ment of technologies used in the design and construction of elevator equipment which has enabled the installation of the equipment in other than traditional locations such as machine rooms. New requirements have also been x added to address programmable electronic systems in safety-related applications of elevators.

The nineteenth edition of the Code incorporates changes made in A17.1a-2008 and A17.1b-2009. Major changes include former periodic inspections now being covered under maintenance requirements. New require-ments have been added to address the means and mem-bers of suspension, compensation, and governor systems for elevators. These new requirements are cov-ered in detail through reference to ASME A17.6, which includes the material properties, design, testing, inspec-tion, and replacement criteria for these means. It includes the requirements for steel wire rope, aramid fiber rope, and noncircular elastomeric-coated steel sus-pension members and provides direction for future con-structions as new technology develops.

This twentieth edition of the Code contains well over one hundred revisions made to existing requirements, as well as some new requirements being added, since the publication of the nineteenth edition.

New requirements have been added to address new types of elevator equipment being used in the industry, specifically wind turbine elevators and outside emer-gency elevators. In addition, requirements have been added to address a new feature called Elevator Evacuation Operation (EEO) which allows for the use of elevators for occupant evacuation.

Besides the above, several major changes include the following:

(a) An extensive update to the seismic requirements of the Code that have been revised to include seismic force levels as specified in the latest building codes in the US (IBC) and Canada (NBCC). In order to facilitate incorporation of these requirements, a Guide for Elevator Seismic Design has been separately published.

(b) Requirements have been updated related to the maintenance control program in order to improve clarity and organization for records, content, availability, and format.

(c) Regarding qualifications for elevator inspectors (QEI), effective January 1, 2014, accreditation of organi-zations that certify elevator inspectors and inspection supervisors is being discontinued by The American Society of Mechanical Engineers. Requirements have been revised in this area to allow for accreditation to be done by other organizations.

The following is a complete list of past editions and supplements to the Code that have been published and the dates when they received final approval. The dates of issuance are also included for the documents published since 1974, and the dates on which they became effective are included for those published since 1978.
