The profundity of entrance (DOP) strategy is a notable ballistic test technique for characterisation and positioning of fired covering materials. The fired tile is attached to a support material of semi-limitless thickness, and the infiltration profundity of the shot gives a proportion of the presentation of the artistic. There is, be that as it may, an inborn fluctuation in the outcomes from this test technique. In this work, the exactness and the changeability of the DOP technique has been researched in a cooperative exercise. Six ballistic test places partook in the activity. A test convention was created, in which the danger type (shot and effect conditions) and a technique on the most proficient method to set up the objectives were determined. The objectives comprised of alumina tiles of two unique thicknesses that were clung to polycarbonate backing 3D shapes. Two distinctive 7.62 mm shield puncturing shots were utilized; one with a hard steel center and one with a tungsten carbide center. The shots and different materials all originated from single material clusters so as to maintain a strategic distance from bunch to-group varieties in material properties. These materials were appropriated between the ballistic test places. The test aftereffects of the distinctive ballistic test offices were gathered and analyzed. There was not a ton of variety between the normal DOP values acquired at every research facility, yet the variety in entrance profundity between shots was high. The outcome of this variety might be less trust in the test outcomes, and a factual strategy was utilized to assess the necessary number of tests that are adequate to get a normal outcome with high certainty. As a rule, the necessary number of tests is a lot higher than what is basically possible. This work was led as a feature of the European Defense Agency-venture CERAMBALL.
