ASME A17.3-2005 pdf download.Safety Code for Existing Elevators and Escalators.
GENERAL This Codeis intendedto serveas the basis forstate and local jurisdictional authorities in adopting retroactive requirements for existing elevators and escalators to enhance the safety of the general public. It is also intended as a standard reference of safety requirements for the guidance of architects, engineers, insurance com- panies, manufacturers, and contractors, and as a stan- dard of safety practices for building owners and managers of structures where existing elevator equip- ment covered in the scope of the Code is used. The purpose of this Code is to establish minimum requirements that will provide a reasonable degree of safety for the general public. While many of these requirements will also increase the degree of safety for the elevator mechanic and inspector, this area has not been specifically addressed at this time. FORM AND ARRANGEMENT This Code consists of ten Parts, each covering a spe- cific subject so as to facilitate reference to the require- ments. As an introduction in each Part, the Scope is described to clearly indicate the applicability of the requirements contained therein. Each requirement has been given an appropriate title with a number to facilitate referencing. The Foreword, Preface, and Appendices that are included in this document have been approved by the A17 Committee, but are not part of this American National Standard. METRIC (SI) UNITS This edition of the Code contains metric (SI) units as well as imperial units. The SI units in the text have been directly (soft) converted from the imperial units. The tables and graphs have not been converted; however, the applicable conversion factors are included for each table and graph. Further information on the use of SI units is contained in ASTM E 380, Metric Practice Guide, and ASME Guide SI-1, Orientation and Guide for Use of SI (Metric) Units. Current committee policy is to have standards pub- lished with information in the form that will best serve the needs of Code users. It is not the intent of the Code to favor a design in SI units over one made in imperial units, or conversely. In converting to SI units, an effort has been made to maintain the precision of the original values so that the accuracy of the converted values is xiii neither exaggerated nor understated. Therefore, if there is a difference in the dimensions or the results ofcalcula- tions between the two systems of units, the imperial units will govern. RECOMMENDED ADOPTION PROCEDURES Prior to an adoption of this Code, a public hearing should be held to permit all interested parties to voice objections they may have to particular Rules, and to provide an opportunity for the adopting authority to explain the reasons for such Rules. Many state laws and city ordinances require such hearings but even where not required, it is strongly recommended that hearings be held. Drafts ofthe proposed Code should be made available to all interested parties at least 30 days prior to the date set for the public hearing. The responsibility of complying with this Code rests with the owner of the existing installation. The owner may assign the responsibility to another party by con- tract. Authorities, intheir legislationadopting this Code, should address this subject. DATE OF APPLICATION At the time of adoption of the Code, the authority having jurisdiction should determine the date existing installations must conform to the requirements. It is recommended that a local committee, consisting of representatives of groups directly interested, be appointed to study the existing local conditions and to determine the length of time existing installations should be given between adoption of this Code and compliance with each provision. Representatives of the following groups should be considered for serving on such a committee: (a) building owners (b) real estate management companies (c) architects and consulting engineers (d) manufacturers of the equipment (e) maintenance companies (f) insurance companies (g) city and state enforcement officials (h) elevator labor unions
