Abstract: Tables of important data for use in the analytical chemistry laboratory are provided. These tables contain information for use in gas chromatography, liquid chromatography, infrared and ultraviolet spectrophotometry, mass spectrometry, and wet chemical techniques. Tables relating to safe practice in the analytical laboratory are also included.

An experimental study is reported to investigate the jump phenomenon in critical flow velocities for tube rows with different pitch-to-diameter ratios and the excited and intrinsic instabilities for a tube row with a pitch-to-diameter ratio of 1.75. The experimental data provide additional insights into the instability phenomena of tube arrays in crossflow.

Abstract: This report presents the results of work at the National Bureau of Standards, Boulder, Colorado, to carefully evaluate, document, develop (when necessary), and describe the methodology for performing radiated susceptibility/vulnerability measurements using a reverberation chamber. The report describes the reverberation chamber theory of operation, construction, evaluation, functional operation, and use for performing immunity measurements. It includes an estimate of measurement uncertainties derived empirically from test results and from comparisons with anechoic chamber measurements. Finally, it discusses the limitations and advantages of the measurement technique to assist potential users in determining the applicability for this technique to their electromagnetic compatibility (EMC) measurement needs.

Abstract: This publication contains papers presented at the Seventeenth International Symposium on Free Radicals, held at Snow Mountain Ranch in Granby, Colorado, on August 18-23, 1985. The Symposium was attended by 147 people, representing industry, government, and academia, from 18 countries. A total of 67 papers appear in written form in this document.

Results of environmental monitoring program conducted at Palos Park.

Significant increases in flow damping were observed for a tube passing through a plate when a sharp-edge raised-diameter constriction was added to the hole in a plate subject to a constant pressure drop. A correlation of the data in the form of a concentrated viscous damper (dashpot) is given which will be useful in structural dynamic analysis.

Highlights of the Chemical Technology (CMT) Division's activities during 1985 are presented. In this period, CMT conducted research and development in areas that include advanced batteries--mainly lithium-alloy/metal sulfide and sodium/sulfur, advanced fuel cells with molten carbonate or solid oxide electrolytes, corrosion-protective coatings for high-strength steel, coal utilization, including the heat and seed recovery technology for coal-fired magnetohydrodynamics plants and the technology for fluidized-bed combustion, methodologies for recovery of energy from municipal waste nuclear technology related to waste management, the recovery processes for discharged fuel and the uranium blanket in a sodium-cooled fast reactor, and proof of breeding in a light water breeder reactor, and physical chemistry of selected materials in environments simulating those of fission and fusion energy systems.

Abstract: This report presents a methodology for evaluating heat detection systems installed in buildings. Previous work for use primarily in designing new thermal fire detection systems was used as a starting point. The previous work was enhanced and supplemented to make it more useful for evaluating existing systems. The resulting equations were programmed into a user interactive computer program. This program is available in both BASIC and FORTRAN and will run on mainframes as well as personal computers. In addition, a modified version of the FORTRAN program was used to develop an extensive set of tables listing detector activation times for given building geometries, detector characteristics, and fire growth rates. These tables are useful for quick evaluation of alternative heat detector installations. Finally practical examples are included to illustrate the use of the tables and computer programs.

Abstract: This directory presents information on 61 U.S. Government certification programs for products and services. Entries describe the scope and nature of each certification program, testing and inspection practices, standards used, methods of identification and enforcement, reciprocal recognition or acceptance of certification, and other relevant details. This directory is part of an ongoing NBS effort to establish and maintain a comprehensive database on standards, regulations, certification programs and related information. This material has bee. compiled to meet the needs of government, industry, and the public for information on U.S. Government certification programs in accordance with the requirements of the U.S. Trade Agreements Act of 1979.
