NDT – Conductivity Testing
Eddy current conductivity testing is an NDT technique that can be used to determine a range of properties of the part being test. Eddy conductivity testing can be used to examine the type of metal or alloy, type of heat treatment, aging of the alloy, effects of corrosion, heat damage, and temper as well as the hardness of non-magnetic materials. The electrical conductivity test can also be used to verify proper heat treatment if used on conjunction with hardness testing.
Electrical conductivity is usually expressed as a percentage of the conductivity of the International Annealed Copper Standard (%IACS) or Siemens/meter (S/m).
