MIL-STD-1537C, DEPARTMENT OF DEFENSE: TEST METHOD STANDARD FOR ELECTRICAL CONDUCTIVITY TEST FOR VERIFICATION OF HEAT TREATMENT OF ALUMINUM ALLOYS EDDY CURRENT METHOD (25 JUN 2002)., This standard contains procedures for verifying aluminum alloy heat treatment by means ofeddy current techniques, which measure electrical conductivity. Aluminum alloy heat treatmentcan be verified when electrical conductivity measurements are used in conjunction withhardness measurements.
