What 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 classifying active cracks in concrete structures.
Who is ISO 16838 for?
ISO 16836 on test method for classification of active cracks in concrete structures is useful for:
- Civil engineers
- Construction industries
- Testers of non-destructive testing
- Manufacturers and producers of concrete
- Agencies which conduct acoustic emission testing.
Why should you use ISO 16838?
The number of aged concrete structures has been increasing all over the world. Cracking is a major cause of damages in reinforced concrete (RC) structures; thus, it is of great help in evaluating crack distribution and cracking mechanisms.
Non-destructive evaluation techniques specified are valuable in decision making on maintenance and repair of the concrete structures. Also, these AE techniques aids in estimating damage, safety and the performance of concrete structures.
The Kaiser effect specified in ISO 16838 helps to examine the absence of detectable acoustic emission.
