New Concept of Ae Standard: Jis Z 2342-2002 “method for Acoustic Emission Testing of Pressure Vessels during Pressure Tests and Classification of Test Results”
نویسندگان
چکیده
Japanese Industrial Standard (JIS) Z 2342 was revised significantly in 2002. The original standard was enacted in 1991 with the title, "Method for acoustic emission testing of pressure vessels during pressure test". The title was also changed, based on NDIS2412 “Acoustic Emission Testing of Spherical Pressure Vessel Made of High Tensile Strength Steel and Classification of Test Results”, which was enacted in 1980. This paper reports the new concept and the contents of the amendment.

On the Use of Acoustic Emission and Digital Image Correlation for Welded Joints Damage Characterization
A series of tests have been conducted to investigate fatigue damage characterization in corroded welded steel plates using structural health monitoring (SHM) techniques. Acoustic Emission (AE) is a non-destructive testing (NDT) technique with potential applications for locating and monitoring fatigue cracks in service. In the present work, AE is implemented to characterize damage during crack e...
متن کاملCluster Analysis of Acoustic Emission Signals for Carbon/Epoxy Composite in Four-point Bending Test (RESEARCH NOTE)
Due to the extensive use of composites in various industries and the fact that defects reduce ultimate strength and efficiency during operation, detection of failures in composite parts is very important. The aim of this paper is to use Acoustic Emission (AE) non-destructive method in four-point bending test of carbon/epoxy composite to analyze and examine the failure mechanisms. This method is...
متن کاملAcoustic Emission Inspection of Spherical Metallic Pressure Vessels
Non destructive evaluation of metallic, spherical pressure vessels is crucial to the safety and operations of a plant due to the large volume of hazardous products stored at high pressures. Sizes of such spheres vary and diameters may range from 10 to 25 meters, even more, while total length of welds can be hundreds of meters. Additionally, accessibility for inspection is often limited, as is t...
