Does NOMOS use nickel-free stainless steel?
The so-called “nickel regulation” has been in effect since June 2000. It says that objects that touch the skin directly and for extended periods of time may only give off 0.5 micrograms of nickel per square centimeter of skin per week. In general, it doesn’t matter how high the percentage of nickel in any given alloy is. Much more important is how much nickel is passed on to the skin. NOMOS uses 316 L stainless steel for all cases and buckles. This type of stainless steel is not fully free of nickel, but it does not pass nickel on to the skin; the amount of nickel in the alloy is about 12 percent. Thus, the amount of nickel passed to the skin is less than 0.2 micrograms per square centimeter per week and far below the medicinally acceptable amount. Other stainless steel alloys might have a lower percentual amount of nickel in the alloy, but they pass more of it on to the skin. 9.
