On January 15, 2026, the ISO/TC 178 Technical Committee of the International Organization for Standardization officially issued the international standard ISO 8100-23:2026 Lifts for the transport of persons and goods — Part 23: Acoustic performance design and test specification, which will officially take effect on July 15, 2026. It is the first special general standard for acoustic performance, noise and vibration control in the global elevator industry. The core contents of this standard include: First, clarify the scope of application of the standard, covering all types of equipment such as passenger elevators, freight elevators, home elevators, and medical elevators, applicable to the acoustic performance control of the whole process of elevator design, manufacture, installation and inspection, adapting to the noise control needs of residential, medical, office, hotel, commercial and other full scenarios. Second, establish a classification system for elevator acoustic performance. According to the use scenario and noise limit requirements, the elevator acoustic performance is divided into four grades: A, B, C and D. Differentiated mandatory limit standards for noise in the car, noise in the elevator lobby, noise in the machine room, and structure-borne sound are formulated for different grades. Third, refine the elevator acoustic design guidelines, formulate special technical guidelines for noise reduction design, vibration isolation, and acoustic damping for elevator hoistways, machine rooms, cars, guide rails, drive systems, and door systems, and clarify the core points of acoustic design for elevators of different speed grades. Fourth, standardize the test method of elevator acoustic performance, formulate a standardized process for laboratory testing and on-site testing, and clarify the unified guidelines for test environment, test instruments, measuring point layout, test conditions, and data processing to ensure the accuracy and repeatability of test results. Fifth, add elevator vibration control requirements, formulate vibration limit standards and test methods for car vibration, guide rail vibration and structural vibration during elevator operation, and standardize the design guidelines for vibration isolation and damping. Sixth, refine the control requirements for low-frequency noise and structure-borne sound of elevators, and formulate special limit standards and design specifications for low-frequency noise and structure-borne sound problems in residential building scenarios. Seventh, standardize the acoustic performance assessment and transformation requirements of in-use elevators, and formulate technical guidelines and acceptance standards for noise control and acoustic performance upgrading of old elevators. After its release, the standard has been launched into the national standard conversion procedure by more than 100 countries and regions around the world such as the European Union, China, the United States and Japan, comprehensively unifying the design and test technical requirements of global elevator acoustic performance.
