Nickel release / REACH compliance for jewelry and buttons

We need a reliable test and documentation process for nickel release on jewelry and garment hardware.

What standard do you test to, and how often?

• EN 1811 / EN 12472
• Sampling by bath or by batch
• Subcontract lab vs. in-house
• Records for customers

Also, how do you handle a failed result without scrapping the whole batch?
