Synosis Points
1
This International Standard gives requirements and test methods for determining the compliance of dental casting investment, dental brazing investment, dental pressable-ceramic investment and dental refractory die materials used in the dental laboratory, regardless of the composition of the refractory powder, the composition of the binder, or the particular application.
2
This International Standard classifies such products into types and classes, according to their intended use and the burn-out procedure recommended by the manufacturer.
3
It also gives requirements for marking, labelling and manufacturer’s instructions.
4
It specifies requirements for the essential physical and mechanical properties of the products and the test methods to be used for determining them.
5
NOTE 1 Compliance with all of the requirements presented in Clause 5 may not be necessary for some products, and a requirement might not be applicable to a product with a particular binder chemistry or be intended for an application in which that requirement is irrelevant. When this is the case, a clear statement to this effect is given according to Clause 5.
6
NOTE 2 A specific quantitative requirement for setting expansion is not included in this International Standard. If the setting expansion of gypsum-bonded investment is measured, then the procedure given in ISO 6873[1] can be considered — a procedure not recommended, however, for investment materials with other binders.
