Why Choose Acoustic Emission Testing?

Acoustic emission testing is a powerful tool in the field of non-destructive testing. It offers several advantages:

• Real-time Monitoring: Allows for continuous observation of materials under stress, providing immediate feedback on their condition.
• Early Detection: Capable of identifying defects at an early stage, preventing potential failures and extending the lifespan of materials.
• Non-invasive: Does not require any physical alteration or damage to the material being tested.
• Cost-effective: Reduces the need for extensive and costly testing procedures by providing accurate and reliable results quickly.

Applications

The BS EN ISO 18249:2025 standard is applicable across a wide range of industries where fibre-reinforced polymers are used, including:

• Aerospace: Ensuring the safety and performance of composite materials used in aircraft and spacecraft.
• Automotive: Testing components for durability and reliability in vehicles.
• Construction: Evaluating the integrity of materials used in building and infrastructure projects.
• Marine: Assessing the condition of materials used in ships and offshore structures.

BS EN ISO 18249:2025

This standard BS EN ISO 18249:2025 Non-destructive testing. Acoustic emission testing. Specific methodology and general evaluation criteria for testing of fibre-reinforced polymers is classified in these ICS categories:

• 19.100 Non-destructive testing

This International Standard describes the general principles of acoustic emission testing (AT) of materials, components, and structures made of fibre-reinforced polymers (FRP) with the aim of — materials characterization, — proof testing and manufacturing quality control, — retesting and in-service testing, and — health monitoring. This International Standard has been designed to describe specific methodology to assess the integrity of fibre-reinforced polymers (FRP), components, or structures or to identify critical zones of high damage accumulation or damage growth under load (e.g. suitable instrumentation, typical sensor arrangements, and location procedures). It also describes available, generally applicable evaluation criteria for AT of FRP and outlines procedures for establishing such evaluation criteria in case they are lacking. This International Standard also presents formats for the presentation of acoustic emission test data that allows the application of qualitative evaluation criteria, both online during testing and by post-test analysis, and that simplify comparison of acoustic emission test results obtained from different test sites and organizations. NOTE The structural significance of the acoustic emission cannot in all cases definitely be assessed based on AT evaluation criteria only but can require further testing and assessment (e.g. with other non-destructive test methods or fracture mechanics calculations).
