Research on Fundamental Theory of Equipment Requirement Demonstration Standardization

The contents of Equipment Requirement Demonstration(ERD)Standardization(ERDS)are analyzed.The emphasis is put on the construction of ERD procedures and the standardization of ERD segments.The principle and basis for the construction of ERD procedures,the main works and their demands for the standardization of ERD segments are put forward,and with two examples followed.It aims to guide ERDS theoretically.
