This International Standard gives the classification of, and specifies requirements and test methods for, dental casting alloys with a noble metal content of at least 25 % (mass fraction) up to but not including 75 % (mass fraction).
It applies to casting alloys suitable for the fabrication of dental restorations and appliances.
NOTE 1 For dental casting gold alloys with noble metal content of 75 % and above, see ISO 1562.
NOTE 2 For dental alloys intended as the substructure of a metal-ceramic dental restorative system, see ISO 9693.
