Non Destructive Testing Article for Medical Industry Published by Quality Magazine
Laboratory Testing Inc. (LTI) had a Non Destructive Testing article for the medical industry published in the April 2017 issue of Quality Magazine. The article, titled “Nondestructive Testing of Implanted Medical Device Materials”, covers a very relevant topic due to pain and other problems that patients could experience if an implanted medical device fails while in use. Additionally, not taking proper precautions can result in serious consequences for the device manufacturer. Testing the materials used for manufacturing implanted medical devices and testing the actual medical devices themselves to ensure integrity is extremely important.
Ensuring Integrity with Nondestructive Testing
The nature of implanted medical devices means that ensuring their integrity is of critical importance. Nondestructive testing, often using multiple methods, is an important part of that assurance. The article discusses two types of non destructive testing that are commonly used to detect defects in material and finished parts without causing any damage to the samples. The step-by-step testing processes are explained in detail for these two specific test methods, Liquid Penetrant Testing (PT) and Ultrasonic Testing (UT), which reveal surface and/or subsurface defects with reliable accuracy.

Although the article was written about medical implants, the basic principles and test methods are relevant to any industry where “high-risk” products are manufactured. For example, certain parts manufactured for aircraft, automobiles and military applications could also cause devastating results if they did not perform as expected. Non destructive testing is a very effective solution for ensuring product integrity for both manufacturers and end users in many industries.
