Results of the test of the beam series RCIP (Table 6.3) and their comparison with calculations by Equation (6.5) are illustrated in Table 6.4. 

Comparison of experimental and calculated values for Mp shows that the difference between them does not exceed 14% when changing the coating thickness from 0 to 90 mm.
