Dental materials-Guidance on testing of wear - Wear by two-and/ot three body contact1 Scope This part of ISO TS 14569 specifies test methods for the assessment of resistance to wear of materials occurring on the occlusal surfaces of restorations, in or on natural teeth or on artificial teeth, as a result of physiological activity in the mouth. Some of the proposed methods include wear from foodstuff as well as, or only, wear by direct contact. The test methods shown in Table 1 are described. This part of ISO TS 14569 is not
