The Magnaflux PeneCert™ Service
Peak penetrant system performance is highly dependent on the integrity of the penetrant materials. Although penetrants are carefully formulated to withstand the abuse and rigors of the aerospace industry, any material is susceptible to contamination and degradation—and penetrant materials are no exception.
Magnaflux recommends that all users perform regular checks on in-use penetrants to comply with industry standards, ensure the conformance of penetrant materials and maintain the quality of penetrant system performance in aerospace inspections. Regular testing also helps establish the point of performance loss and material failure. (Click here to read full-article of In-Use Materials - Key to Maintaining Penetrant System Performance).
Certain specifications require periodic testing of in-use penetrant and materials. These tests are performed at specified time periods depending upon the test and specification requirements. (See chart below)
MAGNAFLUX offers through its PeneCert™ Service, a means to test in-use materials to these various standards for a nominal charge. All testing is performed at our PeneCert testing lab in our manufacturing facility in DeWitt, Iowa by lab technicians with years of experience certifying in-use materials for the various industries. Upon request, a PeneCert kit is supplied with enclosed bottles and documentation for customers to easily return samples to our lab for evaluation.
