Full title and description

STB UNE-EN 12668-3:2014 — Non-destructive testing — Characterization and verification of ultrasonic examination equipment — Part 3: Combined equipment. This is the Spanish (UNE) national adoption of the European standard EN 12668-3 (published as EN 12668-3:2013 / national publication 2014) and specifies methods and acceptance criteria for verification of ultrasonic systems where instrument and probe are assessed together.

Abstract

Defines test procedures, calibration-block-based checks and reporting requirements for verifying the performance of ultrasonic examination equipment when instrument and probe are used as a combined system (pulse-echo A-scan arrangements). The standard provides test descriptions for instrument checks, probe checks and combined system checks (probe, cable and instrument) and gives acceptance criteria and recommended reporting formats; it is not intended to prove suitability of equipment for specific inspection applications.

• Number of pages: ~13 (typical published national PDF runs 11–14 pages depending on national front matter).

Scope

Specifies methods and acceptance criteria to verify the performance of ultrasonic examination equipment when the instrument and probe are used together (combined system). Tests use standardized calibration blocks and are intended for impulse-echo A-scan instruments with step-calibrated gain/attenuation; procedures are suitable for on-site and workshop verification but do not guarantee suitability for any particular inspection application.

Key topics and requirements

• Instrument checks: stability, gain/attenuation linearity, timing and display/recorder functions.
• Probe checks: sensitivity, spectral response, centre frequency and beam geometry characteristics as applicable for contact and immersion probes.
• Combined system checks: tests using calibration blocks that exercise probe, cable and instrument together to verify end-to-end performance and repeatability.
• Use of defined calibration blocks and test pieces, defined test setups and environmental/connection conditions.
• Acceptance criteria and reporting templates for documented verification results; procedures intended for manual inspection equipment and site conditions.
• Notes on limitations: not intended to demonstrate suitability for a given inspection job or for certain special instruments (e.g., dedicated automatic thickness gauges in some cases).

Typical use and users

Used by NDT/UT technicians and inspectors, equipment manufacturers and service/calibration laboratories to verify and document the performance of ultrasonic systems (instrument + probe). Also referenced by quality managers, third‑party inspection bodies and training organizations to define verification routines and acceptance records.

Related standards

Part of the EN 12668 series — see EN 12668-1 (Instruments) and EN 12668-2 (Probes) for complementary characterization and verification procedures. Note: subsequent revisions and replacements in the probe/instrument domain (for example later harmonizations under ISO/EN series such as EN ISO 22232 parts for probe characterization) may affect applicability; users should check current national/regulatory status before relying on the historic text.

FAQ

Q: What is this standard?

A: UNE-EN 12668-3:2014 is the Spanish national adoption of EN 12668-3 (Part 3 of the EN 12668 series) that defines verification methods and acceptance criteria for ultrasonic equipment when instrument and probe are evaluated together.

Q: What does it cover?

A: It covers instrument checks, probe checks and combined system checks (probe, cable, instrument), test procedures using standard calibration blocks, reporting requirements and acceptance criteria for pulse-echo A-scan ultrasonic examination equipment. It does not certify suitability of equipment for specific inspection tasks.

Q: Who typically uses it?

A: NDT technicians and inspectors, equipment manufacturers, calibration and service laboratories, QA/quality managers and training organizations involved with ultrasonic testing.

Q: Is it current or superseded?

A: The publication is listed as superseded/withdrawn in various national catalogs; users should treat the 2014 national adoption as a historical / superseded text and consult their national standards body for the currently valid verification standards and any subsequent replacements (some related EN parts have later revisions or have been replaced by related ISO/EN documents). Specific national catalogs list withdrawal/supersession notices (see national catalog entries).

Q: Is it part of a series?

A: Yes — it is Part 3 of the EN 12668 series (other parts include Part 1: Instruments and Part 2: Probes). The series covers the characterization and verification of ultrasonic examination equipment.

Q: What are the key keywords?

A: Ultrasonic testing, non-destructive testing (NDT), probe verification, instrument verification, calibration blocks, combined equipment, pulse-echo, A-scan, acceptance criteria.
