ISO 18249:2015描述了纤维增强聚合物(FRP)材料、组件和结构的声发射测试(AT)的一般原则,旨在
-材料表征,
-验证测试和制造质量控制,
-重新测试和在用测试,以及
-健康监测。
本国际标准旨在描述评估纤维增强聚合物(FRP)、组件或结构完整性的具体方法,或确定荷载下高损伤累积或损伤增长的关键区域(例如:。
g、 合适的仪器、典型的传感器布置和定位程序)。
它还描述了FRP的AT的可用、普遍适用的评估标准,并概述了在缺乏此类评估标准的情况下建立此类评估标准的程序。
ISO 18249:2015还提供了声发射测试数据的表示格式,允许在测试期间和通过测试后分析在线应用定性评估标准,并简化了从不同测试地点和组织获得的声发射测试结果的比较。
注:声发射的结构重要性不能在所有情况下仅根据AT评估标准进行评估,但可能需要进一步的测试和评估(例如,使用其他无损检测方法或断裂力学计算)。
ISO 18249:2015 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.
ISO 18249:2015 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).
