GB/T 11167-1989

This standard specifies the technical requirements, test methods, and inspection rules for direct acting electrical measuring recorders, which are instruments that record electrical quantities (such as voltage, current, or power) via a direct mechanical linkage without electronic amplification. It is applied in industrial power systems, laboratory testing, and electrical equipment monitoring where continuous, analog recording of electrical parameters is required for analysis or compliance verification. The standard ensures accuracy and reliability in contexts like power grid maintenance, electrical product testing, and quality control in manufacturing environments.
