Abstract
Overview
ISO 16838:2019 defines a test method using acoustic emission (AE) to classify active cracks in concrete structures. The standard supports non-destructive testing (NDT) workflows for assessing damage evolution in reinforced concrete and for prioritizing maintenance decisions. It builds on established AE calibration and terminology standards and describes measurement systems, environmental noise mitigation, test procedures and reporting requirements.
Keywords: acoustic emission, AE, crack classification, RA value, average frequency, concrete structures, non-destructive testing.
Key Topics
- Measurement system and sensors
- AE sensors shall be calibrated in accordance with ISO 12713, ISO 12714 and ISO/TR 13115.
- Broad-band sensors are recommended for parameter analysis; resonance sensors are acceptable when resonance frequencies are higher than 60 kHz in concrete.
- Amplifier internal noise should be low (recommended
