Safety First!!!

We are controlling with below 10PPM in lead to meet CPSC rule(90PPM) in Federal and Proposition 65(90PPM) in California. http://www.cpsc.gov/, https://oehha.ca.gov/proposition-65/about-proposition-65)

Nickel : Nickel Free by EN-12471 Test.

Skin Contact Position Style 
 For Skin Direct Contact checking is made by EN-12472/EN-1811,  EN-12472 test method is 
-Make hurt in two hour by oxidation.
-And put in salty water(Fake sweat) for one week.
-After one week, estimating how many nickel are released in 1㎠ square container. If over 50~28/10,000,000,000(50㎍), it is failing. Problem is material have nickel or no having is not the issue. Even no having nickel material/color also can release nickel by chemical reaction because there have hidden energy/magnetic.
