Scope:

The standard test method, ASTM E1004, can be utilized to determine the electrical conductivity of nonmagnetic materials when used in conjunction with known value reference standards. This test is used to sort metals with respect to variables such as alloy type, heat treatment type (for aluminum, this evaluation should be used in conjunction with a hardness examination), alloy aging, corrosion effects, heat damage, temper, and hardness. Metals with a flat or slightly curved surface and metals with or without a thin non-conductive coating can be tested using this method.

Procedure:

In the ASTM E1004 test, the instrument is connected to a suitable probe coil. Firstly, the manufacturer’s instructions are followed for all necessary settings and control adjustments. Then, at the start of the run, and at least once an hour, the standardization is checked. Finally, the probe coil is placed on the sample whose results are available on the display.

Result

The unit should read within 60.5 percent IACS of the declared value of the standards. 

Conclusion:

The standard test method, ASTM E1004, can be utilized to determine the electrical conductivity of nonmagnetic materials when used in conjunction with known value reference standards.
