Over deze norm
This International Standard specifies requirements for dental resin-based restorative materials 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 the teeth, i.e. class B materials. This standard does not cover requirements for materials intended for the restoration of occlusal surfaces, i.e. class A materials, or materials intended to prevent caries.
