nar resistance is reported in units of k.
The interlaminar resistance determined in accordance with this test method is not the same quantity determined by Test Method A 717/A 717M or Test Method A 718.
This test method is particularly useful for electrical steels coated with inorganic insulating coatings having surface insulation resistivities in excess of 0.3 kcm2 [30 kmm2] when tested using Test Method A 717/A 717M (a Franklin current less than 0.02 A). This test method can readily be extende
