What is corrosion and tarnishing?

The most common defect on hardware is corrosion and tarnishing, where the product changes colour, goes rusty or the surface oxidizes. Low quality hardware usually causes corrosion and tarnishing, due to an inadequate alloy and/or ineffective plating coverage or thickness.

 

Why test your hardware and jewellery for corrosion and tarnishing?

To ensure a high standard of product quality, all hardware and jewellery items need to first be tested as part of your due diligence process.

We test the following products for corrosion and tarnishing:

  • Watches
  • Jewellery
  • Fasteners for clothing and accessories
  • Metal components
  • Mobile phone and tablet cases
  • Metal homeware items
  • Children’s metal toys
