How to relate a certificate of tests (Mill Certificate) to an appropriate standard

Questions you can use to determine if a body jewelry material is tested to relate to an appropriate standard specification

  1. Is contact information available for the supplier, tester and buyer?
  2. Is an ASTM or ISO standard specification for human implant clearly indicated?
  3. Is the quantity and size of the material described on the certificate?
  4. Is the quantity and size sufficient to make the jewelry related to this certificate?

The Association of Professional Piercers agreed upon minimum standards for body jewelry.

Certification of tests that specify a material is suited for human implant purposes is an important part of validating the safe use for body jewelry. There are some historical jewelry materials exceptions such as gold and glass which the APP has allowed based on extensive review, and further particular examples are described below.

The revised Minimum Standard for Jewelry for Initial Piercings is as follows:

  • Steel that is ASTM F138 compliant or ISO 5832-1 compliant
  • Steel that is ISO 10993-6, 10993-10, and/or 10993-11 compliant [Note: The EEC Nickel Directive is a regulation that requires a low rate of nickel release for all materials used for costume or fine jewelry, belt buckles, watches, or other metallic accessories with direct skin contact. It does not specify nor prove that a material is safe to wear in the body; therefore, compliance with this directive alone is not sufficient for meeting the APP initial jewelry standards.]
  • Titanium (Ti6Al4V ELI) that is ASTM F136 compliant or ISO 5832-3 compliant
  • Titanium that is ASTM F67 compliant
  • Solid 14 karat or higher nickel-free white or yellow gold
  • Solid nickel-free platinum alloy
  • Niobium (Nb)
  • Fused quartz glass, lead-free borosilicate or lead-free soda-lime glass
  • Polymers (plastics) as follows:
    • Tygon® Medical Surgical Tubing S-50HL or S-54HL
    • Polytetrafluoroethylene (PTFE) that is ASTM F754-00 compliant
    • Any plastic material that is ISO 10993-6, 10993-10 and/or 10993-11 compliant and/or meets the United States Pharmacopeia (USP) Class VI material classification.
  • All threaded or press-fit jewelry must have internal tapping (no threads on posts).
  • For body jewelry purposes, surfaces and ends must be smooth, free of nicks, scratches, burrs, polishing compounds and metals must have a consistent mirror finish.

This revised wording will be used on all future APP publications and correspondence where the earlier version of the standards was published.

EEC Nickel Directive information

In reference to the EEC Nickel Directive, this regulation does not specify or prove that a material is safe for short or long term wear in contact with the body. It only requires a low rate of nickel release for all material used for costume or fine jewelry, belt buckles, watches or other metallic accessories with skin contact.
