This International Standard specifies requirements and test methods for zinc oxide/eugenol or zinc oxide/non-eugenol cements supplied as two separate components which may be either powder/liquid or paste/paste and which are suitable for use in the oral cavity. These non-aqueous cements may contain eugenol or an aromatic oil, compounds capable of reacting with zinc oxide such as accelerators, and gums, resins and inert inorganic fillers.
