scope:

This International Standard specifies requirements for dental resin-based restorative material supplied in a form suitable for mechanical mixing, hand-mixing, or external energy activation, and intended for use primarily for the direct restoration of class III, IV and V cavities in teeth, i.e. class B materials (see clause 3).

The International Standard does not cover requirements for materials intended for the restoration of occlusal surfaces, i.e. class A materials (see clause 3), or materials intended to prevent caries.
