GB/T7025.1—1997
This standard is a revision of GB7025-86 based on the international standard ISO4190-1:1990 "Installation of Passenger Elevators - Part 1: Elevators of Class I, I, and III", and is equivalent to the international standard in terms of technical content. In order to adapt to the adoption of international standards for elevator products, facilitate international technical exchanges and the import and export of elevator products, this standard adopts a classification method consistent with ISO4190, that is, the categories of elevators are defined as: Class 1: Elevators designed for transporting passengers. Class II: Elevators designed mainly for transporting passengers and also for transporting goods. Class II: Elevators designed for transporting beds. The main difference between Class I and Class III elevators and Class II elevators is the decoration inside the car. Elevators for residential buildings and non-residential buildings are passenger elevators, and Class II elevators are suitable for residential buildings. Class IV: Elevators designed for transporting goods usually accompanied by people. Class V: Miscellaneous goods elevators.
Because special standards have been formulated for hydraulic elevators, this standard cancels the relevant content of hydraulic elevators in the original standard. The contents of freight elevators and miscellaneous goods elevators in GB7025-86 will be moved to GB/T7025.2-1977 and GB/T7025.3-1997 respectively during this revision.
During the implementation of GB7025-86, elevator manufacturers and user departments both hope to expand the elevator parameters. After repeated solicitation of opinions, the unanimously recognized data will be directly added to the standard during this revision. At the same time, brackets are used to distinguish it from the data of ISO4190.
This standard will replace GB7025-86 from the date of entry into force. This standard is proposed by the Ministry of Construction of the People's Republic of China. This standard is under the jurisdiction of the National Technical Committee for Elevator Standardization. The drafting units of this standard are: China Schindler Elevator Co., Ltd., Guangzhou Elevator Industry Co., Ltd., Shanghai Mitsubishi Elevator Co., Ltd., and Shenyang Elevator Co., Ltd.
The main drafters of this standard are: Xiao Hui, Jiang Wenhan, Huang Shankang, Yang Baolin, and Liu Hanxiang. W.bzsosO.coI Engineering Construction Standard Full Text Information System

ISO Foreword
ISO (International Organization for Standardization) is a federation of national standardization bodies (member bodies of ISO) in the world. The preparation of international standards is carried out by the technical committees of the International Organization for Standardization. If a national standards organization is interested in a project and the International Organization for Standardization has established a technical committee for this project, the national standards organization has the right to participate in this technical committee. Governmental or non-governmental organizations that have a connection with international standards can also participate in such work. On the issue of electrical technology standardization, the International Standards Association has close cooperation with the International Electrotechnical Commission. The international standard drafted by the technical committee is being circulated among member countries and a vote will be held on whether it can be used as an international standard. 75% of the member countries must vote in favor before it can be published as an international standard. International standard ISO4190/1 was prepared by the elevator technical committee, namely ISO/TC178 elevators, escalators, moving walkways. The first version (ISO4190/1:1980) has been withdrawn and replaced by the second version. The second version incorporates Annex 2, adds a 320kg elevator, modifies the dimensions of the elevator shaft and car, and retains the 400kg elevator. International standard ISO/4190: "Installation of elevators" consists of the following chapters: Chapter 1 I, I, class elevators
Chapter 2 Class IV elevators
Chapter 3 Class V service elevators
Chapter 5 Controllers, signals and accessories
Chapter 6 Configuration and selection of residential elevators

The lobby depth of each elevator floor shall be maintained at least within the entire shaft width in accordance with the following provisions. These dimensions do not take into account the requirements for the passageway when people who do not take the elevator pass through the floor. Lobby depth refers to the distance between the lobby wall and the opposite wall measured along the depth of the car. W. Engineering Construction Standard Full Text Information System
