From June 10 to 13, 2011, the Secretariat of Jiamusi Explosion-proof Motor Research Institute and Lifting Metallurgy and Shielded Motor Branch organized a working group meeting on drafting five industry standards, including "Technical Conditions for YZPLF Series Lifting and Metallurgical Three-phase Asynchronous Motor with Centrifugal Fan Frequency Conversion and Speed Regulation". Shang Zhikui, Director of Jiamusi Explosion-proof Electrical Machinery Research Institute, Vice-Chairman of Lifting Metallurgy and Shielded Electrical Machinery Branch, and 21 representatives from 16 member units of the Industry Standards Drafting Working Group attended the meeting.

The meeting was presided over by Miao Feng, Director of Industry Information Office of Jiamusi Explosion-proof Electric Machinery Research Institute, Secretary-General of Lifting Metallurgy and Shielding Electric Machinery Branch. Shang Zhikui, Director of Jiamusi Explosion-proof Electric Machinery Research Institute and Vice-Director of Lifting Metallurgy and Shielding Electric Machinery Branch, delivered During the meeting, members of the standard drafting working group drafted "YZPLF Series Lifting and Metallurgical Three-phase Asynchronous Motor with Centrifugal Fan Frequency Conversion Speed Regulation", "YZPZF Series Lifting and Metallurgical Three-phase Asynchronous Motor with Axis Fan Frequency Conversion Speed Regulation", "YZPE Series Lifting and Smelting" by Jiamusi Institute of Explosion-proof Electrical Machinery. Five industry standards (working group discussion draft) of gold electromagnetic brake frequency conversion speed regulating three-phase asynchronous motor, HPB series flameproof shielded motor (with pump) for chemical industry and flameproof shielded motor motor (with pump) technical conditions were discussed carefully, and agreed to discuss and revise them. After the meeting, the standard drafting working group was instructed to complete the compilation of five draft industry standards and send them to all members of the branch and relevant experts for review.
