Overview - ISO/TR 8100-24:2016 (Lift safety convergence)
ISO/TR 8100-24:2016 is a technical report (first edition, 2016) that compares and recommends harmonization of prescriptive safety requirements for lifts (elevators). Its primary focus is the convergence of component-level safety requirements - door locks, buffers, governors, safeties and brakes - across the major regional codes: CEN EN 81‑1, ASME A17.1/CSA B44, JIS TS A 0028-1 and the Building Standard Law of Japan. The report provides side-by-side comparisons, prioritized prescriptive recommendations and guidance aimed at facilitating global alignment of elevator safety requirements.
Key topics and technical requirements
- Comparative analysis of component requirements for:
- Door locks (interlocks, unlocking zones, emergency unlocking)
- Buffers (energy absorption requirements and operational zones)
- Governors (overspeed protection and activation criteria)
- Safeties (safety gear design and engagement thresholds)
- Brakes (design and performance expectations)
- Prioritization scheme for recommendations:
- Priority 1 - items that directly affect component design (to be harmonized first).
- Priority 2 - items that primarily affect system behavior or normative language.
- Practical examples from the report (excerpted): differing definitions and dimensional limits for unlocking/leveling zones (e.g., 0.20 m vs. 0.35 m), and alignment proposals for hoistway door interlocks and closed-position criteria.
- Emphasis on good engineering practice and cross-reference to ISO/TS 22559-2 for implementation guidance.
Practical applications - who uses this standard
- Standards writers and national committees - use the report to inform revisions and promote convergence of regional lift codes.
- Elevator manufacturers and component suppliers - align product design and documentation to meet multiple regional prescriptive requirements and facilitate international trade.
- Test labs and certification bodies - reference harmonized criteria for component testing, approval and cross-recognition.
- Design engineers and consultants - apply reconciled recommendations when specifying safety components for global projects.
- Regulators and building authorities - assess equivalence between regional codes and adopt consistent safety baselines.
