What is the ASTM?

The American Society for Testing and Materials (ASTM) is an organization that has industry specific committees to create standards for everything from toilets to hip replacements.

For the purposes of body jewelry, we’re interested in their standards for materials for human implant. Body jewelry should meet ASTM standards for human implant (such as ASTM F136 for alloyed titanium), because these materials have been tested and proven safe to be in your body for long periods of time. Other jewelry should be treated as novelty pieces and only be worn for short periods at your own risk.
