This document specifies the requirements and test methods for hydrocolloid impression materials. This
document helps to determine whether elastic aqueous agar and alginate hydrocolloid dental impression
materials, as prepared for retail marketing, are of the quality needed for their intended purposes. It also
specifies requirements for labelling and instructions for use. This document does not address possible
biological hazards associated with the materials. Assessment of these hazards is addressed in ISO 7405
and the ISO 10993 series.
