This test method covers the determination of several ac magnetic properties of laminated cores made from flat-rolled magnetic materials. This test method covers test equipment and procedures for the determination of impedance permeability and exciting power from voltage and current measurements, and core loss from wattmeter measurements. These tests are made under conditions of sinusoidal flux.

This test method provides a means for determination of the impedance permeability of ferromagnetic materials under the condition of sinusoidal current (sinusoidal H) excitation. Test specimens in the form of laminated toroidal cores, tape-wound toroidal cores, and link-type laminated cores having uniform cross sections and closed flux paths (no air gaps) are used. The method is intended as a means for determining the magnetic performance of ferromagnetic strip having a thickness less than or equal to 0.025 in. [0.635 mm].

Microstructural, optical, AC dielectric impedance, and conductivity properties of pure PVA and PVA: NaSe SCF samples doped with various NaSe salt fillers were investigated. The XRD study confirmed the semicrystalline structure of the PolVA:NaSe SCF samples which explicated the semi-crystalline nature of the pure PolVA as a matrix.

This work presented the corrosion protection performance of anticorrosion multi-metal hybrid (AC-2MH) complex additive for solder materials in corrosive media. The AC-2MH complex contained traditional additives and organic acids. The Electrochemical impedance spectroscopy results demonstrated the formation of active and passive protective layers on the surface of the alloys, which prevented the solder materials from corrosion.

The frequency dependence of the impedance (C) and AC conductance (G) of all the samples were recorded in a frequency range lower than 10 MHz by using an impedance analyzer HP 4192A. It was found that in the low frequency range lower than 1 MHz the dielectric constant and its loss decrease as Ca substituted for Ba. Besides an abnormal in the frequency dependence of the dielectric constant was observed for all samples in the higher frequency range up to 10 MHz.
