Summary: This standard specifies the small parts (or large components specific area) acoustic emission detection method, since the entire prosecution side region of acoustic emission signals with low attenuation, this approach eliminates the distance-based attenuation correction. This standard feature detection can be applied to materials, production process quality control, product acceptance testing, a large component of the local region of interest during the safety assessment and overhaul inspection. By acoustic emission testing, can bear the load of small parts or internal damage occurs situation and evaluate the load bearing member with a small acoustic emission related activity. This standard does not fully detected, all listed in the safety requirements of the user of this standard to establish appropriate prior obligation to detect safety and health standards.

1 Scope

1.1 standard specifies a small part (or a particular region of large components) acoustic emission detection method, since the entire detection region Acoustically Radio signal has a lower attenuation, the method eliminates the signal attenuation correction based on distance. 1.2 This standard may be applied to detect material characteristics, production process quality control, product acceptance testing, security concerns large component of local area Testing and evaluation and maintenance period. By acoustic emission detection, analysis of small parts to withstand the load conditions or internal damage occurs, and the evaluation and Load associated acoustic emission activity of small parts are exposed. 1.3 This standard does not fully list all of the safety requirements for testing, the user is obliged to use this standard to establish appropriate prior to detection Safety and health guidelines.
