ASTM E3242-20 - Standard Guide for Determination of Representative Sediment Background Concentrations
January 1, 2020 - ASTM International

1.1 This guide focuses on the approach for determination of representative sediment background concentrations used for remedial actions performed under various regulatory programs, including the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)....

ASTM C1778-20 - Standard Guide for Reducing the Risk of Deleterious Alkali-Aggregate Reaction in Concrete
April 1, 2020 - ASTM International

5.1 This guide provides recommendations for identifying the potential for deleterious AAR and selecting appropriate preventive measures, based on a prescriptive-based or performance approach, to minimize the risk of deleterious reaction. In regions where...

ASTM G166-00(2020) - Standard Guide for Statistical Analysis of Service Life Data
February 15, 2020 - ASTM International

4.1 Service life test data often show different distribution shapes than many other types of data. This is due to the effects of measurement error (typically normally distributed), combined with those unique effects which skew service life data towards early failure (infant mortality...

ASTM F1165-20 - Standard Test Method for Measuring Angular Displacement of Multiple Images in Transparent Parts
May 1, 2020 - ASTM International

5.1 With the advent of thick, highly angled aircraft transparencies, multiple imaging has been more frequently cited as an optical problem by pilots. Secondary images (of outside lights), often varying in intensity and displacement across the windscreen, can give the pilot deceptive optical...

ASTM E3240-20 - Standard Guide for Risk-Based Corrective Action for Contaminated Sediment Sites
January 1, 2020 - ASTM International

4.1 This guide provides a consistent and transparent decision-making process for selecting risk-based corrective actions at sediment sites (that is, a Sediment-RBCA). Sediment-RBCA shares the same process as other RBCAs described in E1739, E2081, and E2205/E2205M but with...
