“…The density of the mercury was adjusted for its variation in temperature from 20 °e. We used the values of the thermal expansion of mercury published by Beattie et al [14] . There is an offsetting effect of expansion of the gage blocks; the value in SUMMA reflects the difference between the volume expansion of mercury and the linear expansion of chromium carbide.…”

The range oyer which thermodynamic temperatures have been realized by gas t hermometry at the NBS has been extended to 730 K. The results are preserved by measu ring the corresponding international practical temperatures. The difference b etween them is ex pressed as the foll owing polynomial : 8= -120,887.784/ T.i + 1213.53295/ T 68 -4.3159552 + 6.44075647 X 10-3 T 68 -3.56638846 X 1 0-6 T6~ which is valid in the range 273 to 730 K.The difference found and the es timated uncertainties at the t h ree defining fixed points in the range covered arc

“…In the range of ≈ 20 °C to 350 °C, quartz CTE can be approximated by a linear law α (T) ≈ 11.2+10.9×10 -3 T, with α in μmm -1 °C -1 and T in °C ( Amatuni and Shevchenko, 1966) (see Kosinski et al (1991) for a Taylor expansion of the CTE). However, fused-quartz has a much lower CTE, ≈ 0.42 μm m -1 °C -1 at 25 °C (Beattie et al 1941). It increases nonlinearly up to 0.5-0.6 μm m -1°C-1 at ≈ 200 °C before decreasing monotonically toward 0.42 to 0.54 μm m -1 °C -1 at ≈ 1,000 °C.…”

Aggregate radiation-induced volumetric expansion (RIVE) is a predominant mechanism in the formation of mechanical damage in the hardened cement paste (hcp) of irradiated concrete under fast-neutron flux . Among the operating conditions difference between test reactors and light water reactors (LWRs), the difference of irradiation flux and temperature is significant. While a temperature increase is quite generally associated with a direct, or indirect (e.g., by dehydration) loss of mechanical properties , it causes a partial annealing of irradiation amorphization of α-quartz, hence, reducing RIVE rate. Based on data collected by Bykov et al. (1981), an incremental RIVE model coupling neutron fluence and temperature is developed. The elastic properties and coefficient of thermal expansion (CTE) of irradiated polycrystalline quartz are interpreted through analytical homogenization of experimental data on irradiated α-quartz published by Mayer and Lecomte (1960). The proposed model, implemented in the meso-scale simulation code AMIE, is compared to experimental data obtained on ordinary concrete made of quartz/quartzite aggregate (Dubrovskii et al. 1967). Substantial discrepancy, in terms of damage and volumetric expansion developments, is found when comparing irradiation scenarios assuming constant flux and temperature, as opposed to more realistic test reactor operation conditions.

The functions of the National Bureau of Standards are set forth in the Act of Congress, March 3, 1901, as amended by Congress in Public Law 619, 1950* These include the development and maintenance of the national standards of measurement and the provision of means and methods for making measurements consistent with these standards; the determination of physical constants and properties of materials; the development of methods and instruments for testing materials, devices, ana structures; advisory services to government agencies on scientific and technical problems; in vention and development of devices to serve special needs of the Government; and the development of standard practices, codes, and specifications. The work includes basic and applied research, development, engineering, instrumentation, testing, evaluation, calibration services, and various consultation and information services. Research projects are also performed for other government agencies when the work relates to and supplements the basic program of the Bureau or when the Bureau's unique competence is required* The scope of activities is suggested by the listing of divisions and sections on the inside of the back cover. PublicationsThe results of the Bureau's work take the form of either ^ctual equipment and devices or pub lished papers. These papers appear either in the Bureau's own series of publications or in the journals of professional and scientific societies. The Bureau itself publishes three periodicals available from the Government Printing Office: The Journal of Research, published in four separate sections, presents complete scientific and technical papers; the Technical News Bulletin presents summary and pre liminary reports on work in progressJ and Basic Radio Propagation Predictions provides data for determining the best frequencies to use for radio communications throughout the world. ForewordPreparation of this Monograph on mercury barometers and manometers was undertaken to fill the need of manufacturers and users for information which is now scattered through the literature and in some cases unpublished. This information is primarily on the sources of error and methods for their correction. Moderately extensive tables of corrections for temperature, gravity, capillarity, and other errors are included, mainly for application to portable instruments. The various types of instruments are defined and design features affecting the accuracy discussed in some detail.The preparation of this monograph is part of the work on pressure stand ards now in progress in the Mechanics Division, B. L. Wilson, Chief, under the direct supervision of E. C. Lloyd, Chief of the Mechanical Instruments Section.A. V. ASTIN, Director. in The various designs of mercury barometers and manometers are briefly described, with a more extended discussion of the various design elements which may affect the achievable accuracy. Sources of error in measuring pressures are described in considerable detail, par ticularly for portable instruments, including scale...
