Relevant Discontinuities Series

All purchased items from the store will be fulfilled from our off-site fulfillment center. Any questions about the ordering process and returns should still be directed to ASNT Customer Support, at, or by phone at (800) 222-2768 or (614) 274-6003.

Effective 8 August, ASNT is discontinuing the practice of including paper errata inserts into new books. Customers who purchase a book with existing errata will be notified by email, with a link to ASNT’s webpage listing of errata: Errata should be verified by matching title, edition, and printing. Errata are fixed with subsequent printings and editions.

Relevant Discontinuities: Electromagnetic Testing

Covers discontinuities detectable using alternation current field measurement, eddy current, flux leakage and/ or remote field tesing; includes industrial applications per techinque, as well as presentation of screen displays of selected electromagnetic tests.

* Available In: Spiral-bound PDF


Nonrelevant and False Indications

Flipbook provides comprehensive coverage of false and nonrelevant indications for five major methods: electromagnetic, liquid penetrant, magnetic particle, radiographic and ultrasonic testing. Includes color photographs, radiographic artifacts and screen shots. Corresponds with ASTM and ASME definitions.
