Abstract :
The Japanese Industrial Standard, JIS C-3003, describes the procedure for salt water pinhole testing of magnet wire products. This paper will discuss the industry use of this test, investigations into the critical factors of this testing method, as well as the determination of the different modes of wire insulation failure. A better understanding of the electrochemistry and the magnet wire insulation compatibility aspects of this test has lead to possible use alternative salts in this testing method
