There is a difference between Nickel contain and Nickel release. Surgical Steel 316L always contains 6-13% of Nickel. If someone argues that Surgical Steel has no Nickel in it, it cannot be true since it would not be 316L.
What is the most important is the Nickel release to the body, which should not be more than 0.5%.
The European Nickel free standard states that the rate of nickel release from the parts of products coming into direct and prolonged contact with the skin should not be greater than 0.5 μg/cm2/week. In other words, these products should not release more than 0.05% nickel (no more than 1 part in 2000 should be Nickel).
This rate of nickel release is even lower for piercing: 0.2 μg/cm2/week. (View the materials page to download all our nickel certificates.)
Our products only contain 0.1 μg/cm2/week.
