What Is ASNT ET Level 1 – Electromagnetic Testing?

Electromagnetic Testing (ET) is a nondestructive testing method used to evaluate materials and detect discontinuities without damaging the components being inspected.

Eddy Current Testing (ECT) is one of the most widely used techniques within electromagnetic testing.

The technique uses electromagnetic induction to create circulating electrical currents inside conductive materials. Changes in these currents can indicate cracks, corrosion, variations in material properties, or other discontinuities.

ET is commonly applied in:

  • Aerospace component inspections

  • Heat exchanger and condenser tubing

  • Power generation equipment

  • Automotive component manufacturing

  • Metal tubing, rods, and wire inspection

  • Surface and near-surface crack detection

  • Electrical conductivity and material sorting

  • Nonconductive coating thickness measurement on conductive substrates

What does an ET Level I technician do?

An ET Level I technician typically performs specified inspections using established procedures and approved equipment. Their responsibilities may include equipment setup, system checks, reference-standard comparisons, data collection, and recording inspection results.

Level I personnel work within the limitations of their qualification and the employer’s written practice, typically under appropriate supervision.

Important ASNT references include:

  • ASNT SNT-TC-1A (2024 Edition): Recommended practice for employer-based NDT personnel qualification and certification.

  • ANSI/ASNT CP-105 (2024 Edition): Topical outlines for qualification of NDT personnel.

  • ANSI/ASNT CP-189: Standard for qualification and certification of nondestructive testing personnel, when applicable.

Candidates should always study the editions required by their employer, customer, or governing code.

ASNT ET Level I Training and Certification Requirements

A common question among NDT candidates is whether passing an online ET Level 1 practice test is sufficient to become certified.

The answer is no.

In an employer-based qualification program following SNT-TC-1A, the employer establishes the qualification requirements through its written practice.

These requirements generally include appropriate training, documented experience, examinations, practical competence, and other applicable qualification conditions.

ASNT currently offers Eddy Current Level I training courses providing 40 contact hours, but completing a course alone does not automatically result in certification.

Training-hour requirements and examination arrangements should be confirmed against the applicable certification scheme and employer’s written practice.
