Hello,

As I read IEC 62366-1 2015 it does not mandate that formative testing is required. In particular clauses 5.2-5.4 require you to identify use errors etc but as far as I can make out it does not mandate formative testing. Is this interpretation correct and if so when is formative testing required?

Thanks

Yes, there's no requirement that formative tests are performed, only summative tests are required to be performed as a way to "validate" the usability of the user interface at the end of the process.

Formative tests are important in a HFE/Usability engineering process as a way to identify as quickly as possible, before taking design and development some decisions, usability shortcomings.
