Pre- and post-test observations and inspection results are also provided. If it has to be done quickly and it has to be done right, you can count on EAG. The resulting current between the working and counter electrodes is recorded. These small devices should be tested in their entirety. Our scientists and engineers troubleshoot and solve issues with consumer electronics, chip packages, printed circuit boards, displays, sensors, high-speed communications and more. In our experience, acceptable E b values are most commonly set above mV, and they are often set at much higher threshold values.

Examples of device types that may be evaluated by this test method include, but are not limited to, vascular stents, ureteral stents Specification Ffilters, support segments of endovascular grafts, cardiac occluders, aneurysm or ligation clips, staples, and so forth. The surgical implant materials received were identified as follows: Solution Phosphate Buffered Saline pH 7.

An electrical lead was connected to each specimen.

CTL-ASTM F – Electrochemical Corrosion Testing of Surgical Implants

Utilizing potentiodynamic polarization, a systematic measurement between the environment and metal interface allows comparison of electroactive features like the passivation region of corrosion resistant alloys. Reagents such as phosphate buffered saline are used for the bath, and isopropyl alcohol and type II reagent grade water for atsm rinsing.
