From Abstract: "Comparisons with other other intensity measurements in individual spectra indicate that the National Bureau of Standards spectral-line intensities may have average errors of 20 percent, but first of all they provide uniform quantitative values for the seventy chemical elements commonly determined by spectrochemists. These data are presented by element in part I, and all 39000 observed lines are given in order of wavelength in part II."

From Preface: "This new edition of the NBS Tables of Spectral-Line Intensities incorporates three improvements on the original edition of 1961. In the original edition only about 25 000 of the 39 000 lines in the tables had been classified. In the ensuing thirteen years, about 8500 more lines (chiefly rare-earths) have been classified and the new classifications are here incorporated."

From Abstract and Introduction: "This paper is, in essence, a report on the extension of the techniques first suggested in NBS Monograph 103 "Realistic Uncertainties and the Mass Measurement Process" to the area of length measurement. This paper covers the progress to date on the long gage blocks (from 5 to 20 in the length). The purpose of this purpose is to verify the closure between the "old" process and the "new" process, and to describe the present "points of departure" upon which some of the current assigned length values are based."

Report issued by the Bureau of Standards over a survey conducted on measurement methods of network parameters. As stated in the introduction, "this paper is concerned with the development of automatic methods of measuring basically the magnitudes and phase differences, or the complex ratio of two sinusoidal voltages, and applications of this capability to determining complex reflection coefficients and transmission coefficients and group delay times of electrical networks" (p. 1). This report includes tables, and illustrations.

Report documenting standard x-ray diffraction powder patterns for various compounds, intended to replace previous data or provide information for new substances. It describes the methods and, for each substance, outlines any previous data as well as information about the sample used and structural data, with a table of diffraction patterns.

From Abstract: "This monograph deals with the formulation and development of the new highly stable nickel-base thermocouple alloys Nicrosil (Ni-14.2Cr-1.4Si) and Nisil (Ni-4.4Si-0.1Mg) under the leadership of the Materials Research Laboratories (MRL) of the Australian Government of Defence, and their standardization by the National Bureau of Standards (NBS) of the U.S. Department of Commerce."

From Abstract: "This plan was commissioned to provide a framework for the development of all essential non-nuclear energy-related, environmental, safety, and health (ES&H) standards for the private sector to coincide with the commercialization of energy technologies."

From Introduction: "The first part of this monograph is concerned with the analysis of closed region wave-guide junction problems. This allows simplification of the techniques to be used since no branch cuts are involved in the spectral representation of the fields. However, the analysis can be extended to open region problems in a logical manner. This is the subject of the second part of this monograph."

From Abstract: "Revised reference data for thermocouples have been generated in a cooperative program between groups of the National Bureau of Standards in Boulder and Gaithersburg.This Monograph contains tables, analytic expressions, various approximations, and explanatory text.

From Abstract: "This treatise is an attempt to provide a rational descriptive and analytical basis for tire mechanics. Chapters of this book are contributed by active research workers in the fields of rubber and textile properties, friction, material properties, tire stress problems, tire design and construction, vehicle skid and handling, and tire mechanical properties."

Report issued by the Bureau of Standards over studies on the benefits of computerized record-keeping. Medical records were chosen for the studies, and they also focus on patient privacy and rights. This report includes tables, and illustrations.

From Introduction: "This paper describes some results of the first eight years of a fifteen year program in which a variety of coating and catholic protection systems are evaluated on their ability to protect steel piles in offshore conditions at Dam Neck, Virginia. It includes a description of the methods used in the evaluation and the results found on these systems."

From Abstract: "This document is a review of the principles, procedures, and instruments used in the measurement of visual range. The fundamental concepts of the visual range of the objects and lights are discussed. The principles of operation of the several classes of atmospheric attenuation meters are reviewed and representative instruments are described."

From Abstract: "This compilation abstracts original experimental data on the mechanical, thermal, and electrical properties of six commercially available polymers. The data are also summarized and a brief description of each polymer is included."
