This podcast discusses different types of inspector certifications to hopefully provide clarity on the subject, since there are a number of inspector certifications available through organizations like SSPC, NACE, and more. Featur...
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...
Facility owners frequently rely upon 3rd-party quality assurance (QA) verification of all forms of steel and concrete fabrication, coatings application, non-destructive testing (NDT), and cathodic protection (CP) system installati...
Introduction When applying coating system to structures such as bridges, tanks, and pipelines the main goal is to apply a continuous film to help prevent structural deterioration throughout the life of the structure. Unaddressed d...
When a coating system fails prematurely, it is rarely because of the coating itself. Either the surface preparation was inadequate, the surface was contaminated, or the coating was mixed or applied incorrectly. As the old adage go...
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 “...
This Month’s Case Was Selected From Several Investigations Related To Failures That Occur When Applying Coating To The Underside Of Metal Deck Panels (Fig. 1). This Case Focuses On An Adhesion Failure Of Coatings Applied To Previo...
