One of the areas in which fire hazard assessment techniques have been applied within regulation is for transportation vehicles. In particular, commercial aviation and passenger rail have utilized fire hazard assessment as a means to achieve safety goals well before these techniques became common in buildings. This chapter will review the methods employed and the recent evolution of predictive t...

Corrosive sulfur and the effect that it has in transformer systems can be significant. The extent of the corrosion damage caused by sulfur, if left unchecked, can be so severe as to cause failure of the apparatus. The problems with corrosive sulfur have been recognized for quite some time. As early as 1948, F.M. Clark and E.L. Raab [1] issued a report on the subject for method development withi...

Abstract: Within the American Society for Testing and Materials (ASTM) a Standard Practice (Z6849Z ) is being developed to provide an objective statistical procedure for comparing air quality simulation modeling results with tracer field data. The practice is limited to steady-state local-scale transport from isolated point sources in simple terrain. Evaluation data having similar external cond...

There is currently no general-purpose, open standard for storing data produced by three dimensional (3D) imaging systems, such as laser scanners. As a result, producers and consumers of such data rely on proprietary or ad-hoc formats to store and exchange data. There is a critical need in the 3D imaging industry for open standards that promote data interoperability among 3D imaging hardware and...

An assessment of the sensitivities of the critical parameters in the ASTM D6423 documentary standard method for the measurement of pHe in (bio)ethanol has been undertaken. Repeatability of measurements made using the same glass electrode and reproducibility between different glass electrodes have been identified as the main contributors to the uncertainty of the values produced. Strategies to r...

Numerous experiments on individual buildings in California and Florida show that painting roofs white reduces air conditioning load up to 50%, depending on the thermal resistance or amount of insulation under the roof. The savings, of course, are strong functions of the thermal integrity of a building and climate. In earlier work, we have estimated the national energy savings potential from ref...
