ISO/IEC 14543-5-4:2010(E) specifies device validation methods for information devices that implement ISO/IEC 14543-5-1. It defines an architecture framework for a device validation system used by test devices and devices under test. Also, it describes and specifies the device interaction process, message exchange requirements and conformance rules.
