Non-destructive testing. Acoustic emission testing. Test method for classification of active cracks in concrete structuresWhat is ISO 16838 about? ISO 16838 specifies a test method for the classification of active cracks in concrete structures. The proportion of two AE parameters of average frequency and the RA value is applied to classify cracks into tensile and shear cracks. Acoustic emission testing techniques help to easily estimate the damage, safety and the performance of concrete structures. In this respect, ISO 16838 provides a promising test method for
