Standard Test Method for Determining Electrical Conductivity Using the Electromagnetic (Eddy-Current) Method
Standard Test Method for Determining Electrical Conductivity Using the Electromagnetic (Eddy-Current) Method
Аннотация
Absolute probe coil methods, when used in conjunction with reference standards of known value, provide a means for determining the electrical conductivity of nonmagnetic materials.
Electrical conductivity of a sample can be used as a means of determining: (1) type of metal or alloy, (2) type of heat treatment (for aluminum this evaluation should be used in conjunction with a hardness examination), (3) aging of the alloy, (4) effects of corrosion, and (5) heat damage.
