What is ISO 18563-3 - Performance of combined systems about?
ISO 18563-3 is an international standard that covers the performance of combined system, enabling inspection speed and safety in NDT testing applications.
ISO 18563-3 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–10 MHz.
ISO 18563-3 provides methods and acceptance criteria for verifying the performance of combined equipment (i.e. instrument, probe and cables connected).
Methods described in ISO 18563-3 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.
ISO 18563-3 test procedure also covers the calibration of the system for a specific application.
Note: ISO 18563-3 does not cover -
- Encircling arrays
- Series of apertures having a different number of elements
- Different settings for transmitting and receiving (e.g. 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 (e.g. full matrix capture)
Who is ISO 18563-3 - Performance of combined systems for?
ISO 18563-3 on the performance of combined systems applies to:
- NDT testing agencies
- Testing personnel and inspectors
- Ultrasonic phased array testing services
Why should you use ISO 18563-3 - Performance of combined systems?
Phased arrays are used for inspection and measurement applications. Combined equipment is a connected set including the instrument, the probe and connecting cables including adapters. A combined system is combined equipment including the settings for a given mode of operation.
ISO 18563-3 provides users guidance on modes of operation depending on the number of active apertures, number of delay laws per active aperture, identical or different delay laws for each aperture and examples, enabling ultrasonic testing for a set of beams from different positions.
ISO 18563-3 provides users guidance on requirements for conformity, modes of operation, equipment required for tests, group tests, and system record sheet, enabling users to determine defects in equipment and products.
With obedience and compliance to ISO 18563-3, users can verify the performance of combined equipment, ensuring the detection of defects including cracks, voids, and pits.
