On March 18, 2026, the ISO/TC 178 Technical Committee of the International Organization for Standardization officially issued 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, replacing the old version of ISO 8100-2:2019, which is the core unified guideline in the field of design, manufacture and inspection of core elevator components worldwide. The core upgrade contents of this standard revision include: First, expand the scope of application of the standard, covering all core elevator components such as elevator traction machines, wire ropes, suspension devices, guide rails, buffers, speed governors, safety gears, door systems, and control cabinets, adapting to the component design needs of all types of elevators such as machine-room-less elevators, home elevators, explosion-proof elevators, and fire-fighting elevators. Second, refine the design and calculation rules of elevator components, formulate accurate calculation methods and design guidelines for component load, stress distribution, fatigue life and safety factor under different working conditions, and clarify the minimum safety factor requirements under different use scenarios. Third, upgrade the verification and test requirements of elevator components, formulate the standardized process, test methods and qualification criteria for component type test, factory inspection and on-site test, and add special test standards for non-wire rope suspension devices, carbon fiber components and electronic safety components. Fourth, add the whole life cycle durability requirements of elevator components, clarify the life evaluation method, fatigue test standard, maintenance cycle and scrap criteria of core components, to ensure the safety performance of elevator components in the whole life cycle. Fifth, add the environmental protection and sustainable design requirements of elevator components, formulate relevant guidelines for component material selection, recyclable design, and carbon emission accounting, to promote the green and low-carbon transformation of the elevator industry. Sixth, standardize the document and identification requirements of elevator components, clarify the preparation requirements for component design documents, calculation sheets, test reports and operation manuals, and unify the marking guidelines for component identification, model coding and traceability information. After its release, the standard has been adopted as a national standard by many countries and regions around the world such as the European Union, China, the United States and Japan, realizing the coordination and unification of global elevator component technical standards.
