DIN Standards Committee Materials Testing

Overview

This document (EN ISO 18563-3:2015) has been prepared by Technical Committee CEN/TC 138 "Nondestructive testing", the secretariat of which is held by AFNOR, in collaboration with Technical Committee ISO/TC 135 "Non-destructive testing". This part of ISO 18563 addresses ultrasonic test systems implementing linear phased array probes, in contact (with or without wedge) or in immersion, with centre frequencies in the range of 0,5 MHz to 10 MHz. It provides methods and acceptance criteria for verifying the performance of combined equipment (namely, instrument, probe and cables connected). The methods described are suitable for users working under on-site or shop floor conditions. Its purpose is for the verification of the correct operation of the system prior to testing, and also the characterization of sound beams or verification of the absence of degradation of the system. The methods are not intended to prove the suitability of the system for particular applications, but are intended to prove the capability of the combined equipment to generate ultrasonic beams according to the settings used. The calibration of the system for a specific application is outside of the scope of this document and it is intended that it be covered by the test procedure. This document does not address the following: - encircling arrays; - series of apertures having a different number of elements; - different settings for transmitting and receiving (for example, active aperture, number of active elements, delays); - techniques using post-processing of the signals of individual elements in a more complex manner than a simple delay law (for example, full matrix capture).
