This International Standard gives the classification of, and specifies requirements and test methods for gold-based dental casting alloys with a content of at least 75 % (m/m) of gold and platinum group metals.
It applies to casting alloys suitable for the fabrication of dental restorations and appliances.
It does not apply to alloys intended for use as the substructure of a metallo-ceramic restoration, which is covered by ISO 9693; nor does it apply to dental casting alloys with noble metal content of 25 % up to but not including 75 %, which are covered by ISO 8891.
