GB/T 11028-1999
ActiveTest methods for the determination of bond strength of impregnating agents to an enamelled wire substrate
测定浸渍剂对漆包线基材粘结强度的试验方法
Application Summary AI generated
This standard specifies the test methods for determining the bond strength between impregnating agents (such as varnishes or resins) and the enamel coating on copper or aluminum wire substrates. It is applied in the electrical manufacturing industry, particularly for quality control and material selection in the production of motors, transformers, and other wound components where impregnated windings must resist mechanical stress. The testing context involves preparing standardized twisted wire pairs or other specified specimens, then measuring the force required to separate the bonded wires after curing the impregnating agent.
