This standard is a revision of ZBJ19019-B9T Light machinery wet copper base friction plate technical specification>. Compared with 2BJ1901989, this standard has the following main technical changes: 1. The original standard uses the bonding test to determine the bonding interval. In practice, it is difficult to ensure the same requirements. This standard excluding this method, it is recommended to use the "cold bending" and "turning method" commonly used in the industry for inspection: 2. The original standard's free line shows the relationship between the friction coefficient and the speed during the first joint process. It is not suitable for long-term slipping and long-term joint conditions. The relevant performance indicators of this type of material have been given in the table, so this standard excluding this curve revision; 3. The engineering part of the limit standard is changed to the standard customization. This standard replaces 2BJ19019-89 from the date of implementation. The A list of this standard is the list of standards, which is proposed and managed by the Engineering Machinery Standardization Technical Committee. The drafting units of this standard are: Henan Gemo Metallurgical Research Institute, Beijing Friction Material Factory, Tianban Engineering Machinery Research Institute. The main drafters of this standard are: Chen Jinxin, Lu Naiguang, Pang Shidiao, Zhang Shenhua, Wu Runcai, Yang Chafei. This standard was first issued on May 13, 1989 and first revised in 1999. Fan Gu
