On March 26, 2026, the ISO/TC 178 Technical Committee of the International Organization for Standardization officially issued the new version of the international standard ISO 8100-2:2026 Lifts for the transport of persons and goods — Part 2: Design rules, calculations, verifications and tests of lift components, which is a general guideline in the field of design, manufacture and inspection of global elevator core components, and will officially take effect on September 26, 2026. The core upgrade contents of this standard revision include: First, expand the scope of application of the standard, covering all core mechanical and electrical components of traction, positive drive and hydraulic elevators, add special design and test requirements for non-wire rope suspension systems (carbon fiber composite core, steel belt, etc.) and electronic safety components, filling the standard gap of new elevator components. Second, refine the design guidelines for core mechanical components of elevators, and formulate standardized rules for load calculation, strength check, fatigue life design and safety factor selection for guide rails, suspension devices, cars, counterweights, safety gears, speed governors, buffers and door systems. Third, upgrade the design and test requirements for elevator electrical components, and formulate mandatory standards for electrical performance, electromagnetic compatibility, environmental adaptability and durability test of control cabinets, drive systems, frequency converters, safety circuits and emergency power supplies. Fourth, add the functional safety requirements for electronic safety systems, clarify the safety integrity level (SIL) requirements for electronic speed governors, electronic safety gears, and intelligent safety monitoring systems, and standardize the guidelines for functional safety verification, fault injection testing, and redundant design. Fifth, refine the type test and verification process of elevator components, formulate standardized specifications for type test items, test methods, sample selection, and qualification judgment of different types of elevator components, and unify the test and verification guidelines for elevator components worldwide. Sixth, add the sustainability design requirements for elevator components, and formulate special design guidelines for the recyclability of components, the use of low-carbon materials, and the whole life cycle carbon footprint accounting, adapting to the global carbon neutral development trend. Seventh, add specifications for maintenance and replacement cycle of elevator components, and formulate special guidelines for the service life, maintenance requirements and replacement judgment standards of different core components. 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 elevator components worldwide.
