A century ago, automotive companies developed the laboratory salt spray corrosion test method standardized in ASTM B117. Even then they knew this quality control test did not produce realistic exposures. Wet-dry cyclic tests provided modest improvements in correlation and have been used in architectural applications for many years.
DOWNLOADABLE HISTORICAL DOCUMENT. This NACE standard (material requirements) is one step in a series of committee studies, reports, symposia, and standards that have been sponsored by Group Committee T-1 (Corrosion Control in Petroleum Production) relating to the general problem of sulfide stress cracking (SSC) of metals. Much of this work has been directed toward the oil and gas production industry. Many of the guidelines and specific requirements in this standard are based on field experience with the materials listed, as used in specific components, and may be applicable to other components and equipment in the oil production industry or to other industries. Users of this standard must be cautious in extrapolating the content of this standard for use beyond its scope.
HISTORICAL DOCUMENT. This standard describes a test method to screen scale inhibitors for their ability to prevent precipitation of BaSO4 or SrSO4, or both, from oilfield brines. This standard test method is intended to provide the user with a relative and quantitative measure of the ability of scale inhibitors to prevent (1) the formation and (2) the precipitation of solid BaSO4 or SrSO4, or both, which are necessary and critical stages in scale deposition
In contrast to the Hipster projected or “posed” image based solely upon appearance in lieu of substance, a company’s brand-image projected by paints & coatings requires performance derived from consistently sound chemistry and manufacturing. The protective paints and coatings on the façade of commercial buildings are a significant aspect of the image associated with the owner organization.
Polymeric interior and exterior marine decking systems provide both decorative and functional protection for ships, aircraft carriers, and offshore drilling platforms. Interior decking systems includes coatings, color flake and quartz systems, terrazzo, and underlayments, which are applied in areas such as galleys, living quarters, and wet spaces.
Tensile pull-off adhesion testing is becoming a more frequent specification requirement for in situ quality assurance testing to confirm proper surface preparation and adhesion of high performance protective linings applied to concrete. It is also becoming a widely used test for forensic analysis of protective linings in existing installations. There have been numerous investigations leading to the development of different devices and test pull-off adhesion methods used to assess bond strengths of mortars and overlay materials
This paper takes a look at emerging environmental, health and safety issues that may impact painting contactors and facility owners. Specific topics include OSHA’s hexavalent chromium standard, recent rulings related to multi-employer worksite policy and OSHA’s use of threshold limit values (TLVs®).
