Abstract (in Japanese) (See Japanese page) 
(in English) International standardization activities for control relays were began as the Sub-Committee of IEC/TC41 (Measuring relays and protection equipment) in the late of 1960s. After separation and independence of the Technical Committee from TC41 to TC94, the activities have been continued for more than a half century till now. In Japan, the first Technical Committee was started in Sep. 1970 and the Committee will mark the 200th milestone in Jan. 2018, after transfer of deliberative body from The Institute of Electronics and Communication to Nippon Electric Control Industry Association (NECA) in 1993.
This paper describes, focusing on the following points in above standardization activities for more than a half century:
1) IEC standardization system for control relays;
2) Status of latest IEC standards for control relays;
3) Contribution on the standardization by TC94 National Committee;
4) Market relevant surrounding these relays;
