    1. Scope

    1.1 Structural health monitoring (SHM) is a field of engineering that deals with monitoring and diagnosis of structures during their operation. The primary goal of SHM is detection, identification, assessment, and monitoring of flaws or faults/conditions that affect or may affect the future safety or performance of structures. SHM combines elements of nondestructive testing and evaluation, condition/process monitoring, statistical pattern recognition, and physical modeling. 1.2 The acoustic emission method uniquely fits to the concept of SHM because of its capabilities to examine, monitor, and assess structural integrity during normal operation. 1.3 In this guide, the definitions and fundamental principles of application of the acoustic emission method for tasks of SHM are elaborated. This includes: 1.3.1 Terminology and definitions of SHM by the AE method; 1.3.2 Outline of the recommended application process of AE SHM; and 1.3.3 Fundamental assumptions and principals regarding development of new SHM procedures, selection of equipment, and methods of data acquisition and analysis, diagnosis, monitoring, and prediction by AE SHM are discussed. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    Structural health monitoring is becoming a very large field yet there are no standards dealing with acoustic emission based structural health monitoring.
