Where can a standardized Risk Matrix be found for use within Asset Management Systems aligned...

There is no universally standardized risk matrix in ISO 55000 or ISO 55002. Risk appetite and operational context vary, so each organization must tailor its own framework.

Exact Extract from ISO 55002:2018, Annex D – Risk Matrix Use:

“There is no universal risk matrix provided. Organizations must develop a matrix that reflects their own risk criteria, tolerances, and operational realities.”
