ISO/TC 178/WG 6 - Lift installation

This document covers traffic planning and selection of new passenger lift installations in office, hotel and residential buildings. The requirements and recommendations given are applicable to both simple and complex lift installations. This document gives guidance to select the most appropriate method of traffic planning for each case within the scope. This document permits the number and configuration of lifts and their main characteristics to be determined at the early stages of building design, provided that the size and intended use of the building is known. This document is applicable to lifts classified according to Table 1. This document is applicable to mixed use buildings provided that the mixed use can be evaluated separately as either office, residential or hotel use. This document proposes a standardized method of lift traffic planning. Alternative methods can be valid but are not in the scope of this document. This document gives basic requirements and recommendations as part of the planning and selection of lift(s) relating to: a) the design criteria to be evaluated; b) the values of design criteria to be used; c) a calculation method (see Clause 7) to be used as part of simple planning and selection of lifts (5.3); d) a simulation method (see Clause 8) to be used as part of simple and more complex planning and selection of lifts (5.3); e) output report format of lift planning and selection analysis to be provided to interested parties; f) consideration of existing safety standards and cultural norms for determining the number of persons that can fit into a specific size of car[1]; g) accommodation for luggage, bicycles, prams, etc., or other non-personal items that can be transported with passengers in the lifts; h) accessibility for persons with disabilities. This document does not address: i) the transportation of goods only; j) the transportation of passengers using multiple cars sharing a single hoist way; k) the transportation of passengers using double deck systems; l) terminal to terminal travel in excess of 200 m and/or rated speed above 7 m/s; m) variations to the calculation method (e.g. traffic conditions other than uppeak, door dwell time definitions, unequal floor heights, unequal floor populations, speed not being reached in one floor jump, etc.); n) variations to the simulation method (e.g. passenger batches or traffic templates with variable passenger demand); o) design of simulator models or traffic control systems; p) advanced passenger features (e.g. walking speed); q) performance verifications of the design after installation. [1] The European Lift Directive 2014 refers to the car as a carrier.

This document specifies the necessary dimensions to permit the installation of passenger lifts of class I, II, III and VI. These dimensions reflect the requirements for the apparatus. This document is applicable to all new lift installations, irrespective of drive systems, including a car with one entrance, to be installed in a new building. However, for arrangements with counterweight at the side, a through-entrance configuration is possible. Where relevant, this document is also applicable to an installation in an existing building. This document is not applicable to lifts of rated speed greater than 6,0 m/s. NOTE It is the responsibility of the user to consult the manufacturer for such installations.

ISO/TS 18870:2014 details requirements for passenger carrying lifts, which are installed in buildings having a suitable comprehensive building evacuation strategy. It does not define building requirements that will have to be provided as part of the overall evacuation strategy for the building. Excluded from ISO/TS 18870:2014 are the following: details of a building evacuation strategy; details of building features to reduce risks or eliminate hazards; national building requirements which might demand special features.

ISO/TR 25743:2010 investigates and highlights the main risks associated with using lifts (elevators) for the evacuation of persons in various types of emergency. The types of emergency under study arise from fire, flood, earthquake, explosion, biological or chemical attack, gas leakage, lightning or storm damage in the building being studied or a building adjacent to it. The purpose of ISO/TR 25743:2010 is to provide a process for making decisions relevant to the design of lifts and buildings, in order to determine if a given design can enable the lifts involved to be used with an acceptable level of safety.

ISO/TR16765:2003 consists of a comparison of the requirements of selected topics as covered by standards in use in the following parts of the world: Europe, Australia, Russia, Japan, USA, Canada, China, Hong Kong, India, Korea, Malaysia, New Zealand, Singapore, Taiwan. This Technical Report applies to electric traction lifts only, although some sections may also be applicable for positive drive lifts and other lifts suspended by rope or chain.
