Introduction – Aluminum and aluminum alloys exhibit good corrosion resistance by virtue of a layer of aluminum oxide that forms on the surface. While aluminum is often not coated because of its good corrosion resistance prop...
This video discusses calibration of type 2 electronic inspection gages, and verification of accuracy and adjustment. It provides definitions, tools to adjust/verify, frequently asked questions, and more. Featuring KTA Chief Operat...
Quality programs frequently require instrumentation used to obtain measurements (to determine conformance to a governing specification) to be calibrated and verified for accuracy, but oftentimes do not provide the frequency or met...
ANSI/ASHRAE/IES Energy Standard 90.1-2010 and the 2012 International Energy Conservation Code require that building envelopes be designed to limit uncontrolled air leakage into and out of buildings. Air leakage in buildings is con...
Introduction Adhesion is an important physical characteristic of applied coating films and systems, and testing is frequently used as an indicator to whether an adequate bond exists between the substrate and primer (first coat) an...
Background/Introduction The AASHTO/AWS D1.5M/D1.5 Bridge Welding Code: 2015 published by the American Welding Society (AWS) covers the welding requirements for The American Association of State and Highway Transportation Officials...
Introduction Surface profile is defined as a measurement of the maximum peak-to-valley depth generated by abrasive blast cleaning and impact-type power tools. These operations effectively increase the surface area and provide an “...
For many in the health care/fitness industry, BMR is an acronym for basal metabolic rate. Sorry to disappoint if you thought this would be a health science article about expending energy. Rather, this article is about a different ...
Chemical contaminants on a surface can include chlorides, ferrous ions, sulfates and nitrates, among other types of soluble salts. Chloride may come from deicing materials or marine/coastal environments, ferrous ions are a by-prod...
Introduction The hardness of a coating material is a relative property that may be interpreted in a variety of ways by different industries that use coating/lining materials. While hardness testing is frequently used to assess th...
