Chapter 5 contains the prescriptions for the risk reduction measures to be implemented in an Industrial Robot Cell.
First of all, please notice the change in the title, compared with the 2011 previous edition, which was “5 – Safety requirements and protective measures”. As you can notice, the term “Protective Measures” has been replaced with the term “Risk Reduction Measures”. That is a trend we already indicated on our website and it will be done in all ISO standards linked to Machinery Safety, starting with ISO 12100, at the moment (2025) under revision.
5.2.12 Hazardous energy
There is now a new paragraph on Hazardous Energies. It is now required, not only that the possibility to isolate and lock all the sources of Hazardous Energy, but also that their location is made visible.
[ISO 10218-2: 2025] 5.2.12.2 Isolation of sources
[…] Each isolation device shall be readily identifiable as to what it isolates (e.g. by durable marking where necessary). The span-of-control for each of these devices shall be clearly marked near the disconnecting device (e.g. text or symbol).For electrical supply disconnecting devices, IEC 60204-1:2016+AMD1:2021, 5.3.1 shall be applied.
For energy separation and dissipation requirements, ISO 14118:2017 shall be applied.
5.2.16 Cybersecurity
Cybersecurity is entering all new standards, also given the fact the new Machinery Regulation has introduced the EHSR 1.1.9.
[REGULATION (EU) 2023/1230] 1.1.9. Protection against corruption
The machinery or related product shall be designed and constructed so that the connection to it of another device, via any feature of the connected device itself or via any remote device that communicates with the machinery or related product does not lead to a hazardous situation.
The prescriptions are a bit generic, since, by the time the MR will come into force (Jan 2027), there will be an Harmonised European Standard to comply with: EN 50742: Protection against corruption.
5.5 Safety functions
The chapter has been widen, with a whole new list of Safety Functions specific to the Robots. However, the standard now allows to run a risk assessment and decide a different level of reliability than indicated in the Annex C.
Finally both ISO 13849-1 and IEC 62061 are clearly indicated as equivalent Functional Safety Standards for Industrial Robot Application.
5.14 Collaborative applications
Collaborative Applications are now well detailed in the ISO 10128-2. Please look at this link.
