When coatings degrade from UV exposure, they can become more susceptible to corrosion attack. In the early 1990s, ISO and ASTM standardized a combined corrosion/weathering cycle. Today, this is still considered the most effective test method for dete...

This paper is intended as a general introduction to cyclic corrosion testing (CCT). It outlines the rationale for cyclic testing, includes some guidelines for using cyclic tests and explains some common CCT cycles and their applications. This discuss...

It is widely accepted that improved methods for assessing the corrosion controlling properties of organic coatings on steel are needed. Difficulties with established testing procedures (primarily ASTM B 117 salt spgy) have been well documented]-3 and...

Salt spray cabinets were first used for corrosion testing around 1914, In 1939, the neutral salt spray test was incorporated as ASTM Method B 117, Today B 117 is the Practice for Operating Salt Spray (Fog) Apparatus under the jurisdiction of Committe...

Within the generic categories of rail car exterior coatings, there are significant variations in performance. Therefore, testing is required to select coatings that will give the best performance. Outdoor exposure tests produce meaningful results but...

A wide variety of low solvent-containing coating systems for steel bridges were evaluated by various laboratory test methods and the results were compared with the results of duplicate systems exposed at Sea Isle City, New Jersey.Download File

This article presents a brief description of the various approaches to determine longterm durability of coatings. Following the introduction, some data from SSPC's Performance of Alternate Coatings in the Environment (PACE) program are presented, com...

This paper describes a method of Cyclic Accelerated Corrosion known as the Mebon Prohesion Test. This test relates more closely to long term natural exposure than do conventional salt spray, humidity or sulphur dioxide tests. The Prohesion test usual...

Organic coatings are commonly used to protect metallic engineering structures from degradation caused by natural or artificial environments. A recent estimate suggests that in 1986, the total value of shipments of paint and allied products in the U. ...
