1.3.1 Purpose The purpose of this Code is to provide for the safety of life and limb and to promote the public welfare. Compli- ance with this Code shall be achieved by either of the following:
(a) conformance with the requirements in ASME A173
(b) conformance with some of the requirements in ASME A17.3 and, for systems, subsystems, components, or functions that do not conform with certain require- ments in ASME A17.3, conformance with the applicable requirements in ASME A17.1/CSA B44 (see Section 1.2)
(c) conformance with some of the requirements in ASME A17.3 and, for systems, subsystems, components, or functions that do not conform with certain require- ments in ASME A17.3, conformance with the applicable requirements in ASME A17.7/CSA B44.7 (see Section 1.2)
(d) conformance with the requirements in ASME A17.1/CSA B44 (see Section 1.2)
(e) conformance with the requirements in ASME A17.7/CSA B44.7 1.3.2 Exceptions The provisions of this Code are not intended to prevent the use of systems, methods, or devices of equivalent or superior quality, strength, fire resistance, effectiveness, durability, and safety to those prescribed by this Code, provided that there is technical documentation to demon- strate the equivalency of the system, method, or device.
1.3.2.1 Where a requirement, because of practical diffi- culty, cannot be complied with literally or where its literal application would cause undue hardship, the authority having jurisdiction shall be permitted, upon proper appli- : cation, to grant exceptions, but only when it is clearly evident that reasonable safety is ensured.
1.3.2.2 The authority having jurisdiction shall also be permitted to grant exceptions or permit alternate methods where it is ensured that equivalent objectives can be achieved by establishing and maintaining effective safety.
Section
1.4 defines various terms used in this Code. In addition, some nomenclature and terminology used in the elevator industry and other ASME publications are defined. access switch: see hoistway access switch. alteration: any change to equipment, including its parts, components, and/ or subsystems, other than maintenance, repair, or replacement.
alteration, as a part of an: a repair or replacement that is included with other work that is classified as an alteration. alternate level: a floor level identified by the building code or fire authority, other than the designated level.
annunciator, car: an electrical device in the car that indicates visually the landings at which an elevator landing signal registering device has been actuated.
applied, frame entrance: a wraparound or partial addition to an existing entrance frame used to improve the appearance or to provide the required clearances. approved: acceptable to the authority having jurisdiction. authority having jurisdiction: the organization, office, or individual responsible for enforcement of this Code.
Where compliance with this Code has been mandated by legislation or regulation, the “authority having jurisdiction” is the regulatory authority (see regulatory authority).
authorized personnel: persons who have been instructed in the operation of the equipment and designated by the owner to use the equipment.
automatic transfer device: a poweroperated mechanism that automatically moves a load consisting of a cart, tote box, pallet, wheeled vehicle, box, or other similar object from and/or to the car.
quxiliary power lowering device: an alternatively powered auxiliary control system that will, upon failure of the main power supply, allow a hydraulic elevator to descend to a lower landing.
base, building: the level at which the horizontal seismic ground motions are considered to be imparted to the structure. brake, driving machine, elevator, dumbwaiter, or material lift: an electromechanically or electrohydraulically released spring, or gravity applied device, which is part of the electric driving machine of the elevator, dumbwaiter, or material lift used to apply a controlled force at a braking surface to hold or retard the elevator, dumbwait- er, or material lift.
