ISO/IEC 20243-2:2018 specifies the procedures to be utilized by an assessor when conducting a conformity assessment to the mandatory requirements in the Open Trusted Technology Provider? Standard (O-TTPS).1
These Assessment Procedures are intended to ensure the repeatability, reproducibility, and objectivity of assessments against the O-TTPS. Though the primary audience for this document is the assessor, an Information Technology (IT) provider who is undergoing assessment or preparing for assessment, may also find this document useful.
