IS 1068 specifies nickel-chromium electroplated coatings for corrosion protection and decorative finish. Service conditions SC1 (mild indoor) to SC4 (severe outdoor) determine minimum coating thickness. Widely used for bathroom fittings, door hardware, and automotive trim.
Specification for electroplated nickel and chromium coatings on metal substrates for corrosion protection and decorative finish.
Key Values
SC1 (mild indoor) Ni thicknessMin 5 µm
SC2 (moderate) Ni thicknessMin 10 µm
SC3 (severe indoor) Ni thicknessMin 20 µm
Practical Notes
! Always specify the service condition (SC1-SC4) in procurement — it determines coating life.
! SC4 is required for external building hardware (door handles, railings exposed to weather).
! Chrome over nickel is decorative + protective. Nickel provides corrosion resistance; chrome provides hardness and appearance.
! CASS test (copper-accelerated acetic acid salt spray) is the standard corrosion test for Ni-Cr coatings.
