ISO/TS 8102-21:2026 is an important standard developed by ISO/TC 178 Technical Committee for the digital development of elevators, totaling 16 pages. The standard clarifies the full lifecycle management requirements for software updates, including:

1) Software version control and traceability mechanisms;

2) Safety verification processes for on-site updates and over-the-air (OTA) updates;

3) Rollback mechanisms and emergency handling measures in case of update failures;

4) Functional testing requirements before and after software updates;

5) Preservation and management specifications for software update records.


The standard particularly emphasizes that any software update affecting elevator safety functions must be performed by authorized professional personnel and undergo comprehensive safety testing. This standard complements ISO 8102-20 cybersecurity standard, together forming a complete system for elevator digital security.
