IS 19362 : 2025 Non-Destructive Testing - Eddy Current Testing - Determination of Electrical Conductivity of Non-Magnetic Metals
1 SCOPE
1.1 This test method covers a procedure for determining the electrical conductivity of nonmagnetic metals like copper, aluminium, titanium, zirconium & their alloys, and austenitic stainless steel using the electromagnetic (eddy current) method. The procedure is primarily for use with commercially available direct reading electrical conductivity instruments.
1.2 This test method is applicable to non-magnetic conductive materials that have a flat surface and includes metals with or without a thin nonconductive coating.
1.3 Electrical conductivity, when evaluated with eddy current instruments, is usually expressed as:
a) Percentage of the electrical conductivity of the International Annealed Copper Standard (percent IACS)
b) Siemens/meter (S/m). The conductivity of the annealed copper standard is defined to be 0.58 × 108 S/m (100 percent IACS) at 20 °C.
