Fatigue fretting is the process of crack formation and progressive crack growth at a location in a mechanical system where two components are in contact and undergoing a vibratory loading. A new ASTM International standard provides insight on what conditions promote fretting fatigue and offers approaches to design an experiment to assess it. ASTM E2789 , Guide for Fretting Fatigue Testing, was…, ASTM Committee E08 Next Meeting:, May 16-20, May Committee Week, Anaheim, Calif., Technical Contact:, Richard W.

ASTM International Committee E07 on Nondestructive Testing has recently approved three new standards on phased arrays, polymer matrix composites for aerospace applications and digital imaging. The committee will be meeting in Plantation, Fla., on Jan. 24-28 and welcomes participation in its standards developing activities., Ultrasonic Methods, Thousands of portable phased array units, used for weld inspections, have now been sold worldwide. There are many benefits to these devices, including speed, cost, imaging, flexibility and setups, along with no radiation, licensing or contamination. Despite these advantages, there was not a universal inspection procedure for phased array inspection of welds. A new standard, E2700 , Practice for…, Specialized NDT Methods, A new guide gives an introductory overview that describes how mature and established nondestructive testing methods that are routinely used by industry are applied specifically to the characterization of polymer matrix aerospace composites. E2533 , Guide for Nondestructive Testing of Polymer Matrix Composites Used in Aerospace Applications, is under the jurisdiction of Subcommittee E07.10 on…, Digital Imaging and Communication in Nondestructive Evaluation, A new standard developed by Subcommittee E07.11 on Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) will fill a need in the nondestructive testing industry for a transparent and industry standard data format with which to store digital inspection data. E2663 , Practice for Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for Ultrasonic Test Methods…, WK17435,, Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for X-Ray Computed Tomography (CT) Test Methods;, WK17436, , Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for Digital Radiographic (DR) Test Methods;, WK20537, , Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for Eddy Current Test Methods; and, WK22505,, Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for Computed Radiography (CR) Test Methods.
