The final draft of IEC 61557-8, IEC 61557-9, and IEC 61557-16 was discussed at this meeting, and the editorial comments made by various national committees on the draft standard were handled. In addition, the other parts of IEC61557 were combed and plans to initiate the revision of the three standards. Chinese experts expressed active support and nominated Chen Wenxin to participate in the standard revision team. Since Mr. Wolfgang Hofheinz, the leader of Working Group 8, will retire at the end of 2014, he proposes that Dieter Feulner succeeds the team leader and the experts unanimously adopted the proposal. At the same time, the working group welcomed Mr. Wolfgang Hofheinz in a special way. When the photos of each working group from 2001 to the present were displayed on the projection screen and were accompanied by his explanations of his standardized work performance, he was very knowledgeable and had white hair. The pale, super-charismatic old man's eyes were moist. He said: “I have been engaged in the standardization business for 30 years and participated in several technical committees. However, the TC85 family is my favorite, and these work achievements are also for us all. The result of cooperation and cooperation!†At the same time, he also hopes that Working Group 8 will continue to be brilliant under the leadership of the chairman and secretary of TC85 and establish more high-quality standards.
