NF EN ISO 5139, S91-513 (05/2023)

This document specifies the characteristics of machinable polymer composite blanks to be determined for milling. It also provides testing methods to address the clinical issues specific to these materials. In addition, this document specifies the elements which must appear on the packaging and on the materials as well as the information to be provided in the instructions for use. The machinable polymer composite blanks discussed in this document are blanks used for the fabrication of permanent dental restorative devices (e.g., single crowns or inlays) by milling. This does not concern large blanks (for example, discs) allowing the manufacture of at least two crowns or bridges from a single blank or temporizing materials.
