ISO 18563-2:2017

Overview

ISO 18563-2:2017 - "Non-destructive testing - Characterization and verification of ultrasonic phased array equipment - Part 2: Probes" specifies the end-of-fabrication characterization tests for ultrasonic phased array probes. It defines required methodology and acceptance criteria for probes used in contact (with/without wedge) or immersion techniques with centre frequencies from 0.5 MHz to 10 MHz. Applicable probe types include non-matrix arrays (linear, encircling, partial annular/“daisy”) and 2D-matrix arrays. The standard focuses on probes only; instrument and combined-system tests are covered in ISO 18563-1 and ISO 18563-3.

Key Topics and Requirements

• Scope & applicability: Tests at probe connector after final assembly; contact and immersion techniques; frequency range 0.5–10 MHz.
• Documentation & traceability:
  • Probe data sheet (technical specs) and probe test report (measured values, test equipment/conditions).
  • Probe marking with manufacturer ID and unique serial/reference number; declaration of conformity.
• Required test equipment:
  • Oscilloscope with minimum 100 MHz bandwidth.
  • Spectrum analyser (or FFT-capable oscilloscope) minimum 100 MHz.
  • Relevant test blocks, wedges or immersion setups; details must be recorded in the test report.
• Performance tests specified (methodology and acceptance criteria defined in Clause 8):
  • Physical aspects (geometry, contact face, integrated wedge details).
  • Relative pulse-echo sensitivity variation - element-to-element uniformity.
  • Frequency, bandwidth and pulse duration - per-element and average values.
  • Probe sensitivity - overall probe response.
  • Inter-element cross-talk (optional) and number of elements out of specification (rules for 2D-matrix arrays).
• Testing conditions: Tests should reproduce intended use (wedge present/removed, immersion fluid specified or water by default). Acceptance criteria are valid only under stated test conditions.

Applications and Users

ISO 18563-2 is intended for:

• Phased array probe manufacturers - production acceptance testing and final inspection.
• NDT laboratories and test houses - incoming inspection, certification and performance verification.
• Quality assurance/Procurement - supplier compliance, procurement specifications.
• R&D and probe designers - baseline characterization, design verification.

Practical uses include manufacturing quality control, supplier acceptance, probe data sheet generation, and producing probe test reports for traceability and conformity.
