Pin hole test for enameled wire is to find insulation defects after treatment with a salt water solution.

Magnet wires are broadly divided into enamelled wire (coating insulation), covered conductor wire (fiber/film insulation), and combinations thereof. Both magnet wire types as well as their performance are quite varied. 

Listing Enameled Winding Wire Test IEC60815, 20 type tests, LP indUstry does these test to ensure quality of enameled winding wire, just enameled aluminum wire and enameled copper wire

How to do Continuity Of Insulation Test according to Standards, listing the IEC 60815 standard.

Electrical Resistance Of Enameled Wire

How to do solderability test of enamelled round wire? Most of enameled wire buyer should be required the solderability, and the enameled wire manufacturer should be done the test, according to standard, listing the test of enamelled round wire.

According to IEC 60851 -5:2008, we should choose the refrigerant, such as monochlorodifluoromethane. The breakdown voltage is determined after exposure of the specimen to the refrigerant under pressure and at elevated temperature. This test is applicable to enamelled round wire with a nominal conductor diameter over 0,250 mm and to enamelled rectangular wire.
