It has become a common scene: a driver in a parking lot suddenly loses control of a car, sending it into a storefront or other pedestrian area. In an effort to minimize the injury and damage caused by such crashes, ASTM International Committee F12 on Security Systems and Equipment is developing a proposed new standard, WK13074 , Test Method for Crash Testing of Low Speed Pedestrian Barriers. The…

X-ray fluorescence spectrometry is used often to determine a wide range of elements in alloys. The technique provides rapid, accurate, and precise multi-element analysis that enables efficient melt process control. It is also widely used for certification and over-check analysis of product. Although x-ray fluorescence has become a widely used technique of analysis by the nickel alloy industry,…
