Certified Reference Materials. Certified Reference Materials are materials whose properties have been guaranteed or certified by recognized bodies. The certified analyses of these materials can be used as an estimate of the "true" value for assessment of accuracy. The United States National Bureau of Standards (NBS) provides an inventory of various materials whose compositions (and properties) have been measured using definitive and reference methods. These materials, Standard Reference Materials (SRM s), when used in conjunction with reference methods, i.e., one of demonstrated accuracy, make it possible to transfer accuracy between measurement protocols. [Pg.252]

Major component, best determined by other means,—i.e., the analyst has little confidence in this value. b Sample 3 is standard reference material 124c from the United States National Bureau of Standards. The last line (NBS values) shows the values on the analysis certificate, based on a number of wet determinations for each element using 1-gram samples. The alloy also contains P =. 024%, Si =. 002%,... [Pg.189]

While thermal energy units were defined for many years as indicated above, it is now customary to define them arbitrarily in terms of mechanical units, with no reference to the heating of water. At the present time, there are two defined gram-calories in wide use, the United States National Bureau of Standards thermochemical... [Pg.96]

In the early 1950s, the United States National Bureau of Standards evaluated a battery electrolyte additive which contained sodium sulfate and magnesium sulfate. The manufacturer s claim was that the additive could restore the performance of... [Pg.125]

The usual standards for pH measurement are 0.05 m potassium hydrogen phthalate and 0.01 M sodium borate buffers having the assigned values given in Table 3.1. (Strictly, the United States National Bureau of Standards (NBS) standards are based on molalities (moles per kg. [Pg.25]

This has led to attempts to develop pH scales which have a sounder theoretical basis, where the asterisk now indicates that the value is measured relative to an ideal dilute solution in the same solvent. The pH scales are estabhshed on the basis of assigned values to particular buffers in the solvent systems, in a manner strictly analogous to the way in which the pH scale has been defined for water. Most of the work in this field has been done by Bates and his colleagues at the United States National Bureau of Standards, and by de Ligny and co-workers in the Netherlands. [Pg.78]

Wayne B. Gray is Professor of Economics at Clark University, a Research Associate of the National Bureau of Economic Research and Coordinator of the Boston Research Data Center of the United States Census Bureau. Gray s research focuses on the consequences of environmental regulation for productivity and risk management. He received an A.B. from Dartmouth College, and an M.A. and Ph.D. from Harvard University. [Pg.318]

Several extensive series of soil-corrosion tests have been carried out by the National Bureau of Standards in the United States, and the results have been summarised by Romanoflf. In one series two types of copper and ten copper alloys were exposed in fourteen different soils for periods up to 14 years. The results for the copper specimens are summarised in Table 4.12. [Pg.692]

FIGURE 6.1 The United States is becoming ever more dependent on foreign sources of oil and minerals. The top graph displays trends in U.S. production and consumption of petroleum feedstocks from 1970 to 2000. It shows the growing contribution of imported oil to U.S. consumption, a contribution that is projected to increase rapidly in the 1990s. The bottom table shows that the United States depended in 1985 on foreign suppliers for 20 minerals and metals, some of which are critical to national security.

Science cannot be performed without an accurate system of measurement, which is globally standardized and compulsory. Units and standards of measurement are agreed upon and harmonized on an international basis by the Bureau International des Poids et Mesures in Sevres, France, and by the International Organization for Standardization in Geneva, Switzerland. The units and standards are then laid down in national laws. Nearly all countries have accepted the Systeme International d Unites (SI units) as their system of measurement. This also applies to countries that had been accustomed to use British units like Australia, Canada, South Africa and the United States. In Britain, SI units are official from January 2010. The valid standards are available from the competent bureaus, for example Bureau International des Poids et Mesures, www.bip.fr National Measurement Institute (Australia), www.measurement.gov.au National Institute of Standards and Technology (NIST, USA), www.physics.nist.gov/ Pubs/SP811/... [Pg.247]

United States has a total value of about 15,000,000. In 1948, 35,000,000 pounds were produced of one insecticide alone—DDT (9). There are about 25,000 plant diseases in the United States, including 10,000 of economic importance, and these cost the nation about 4,000,000,000 a year. The annual wholesale value of all agricultural chemicals in the United States is about 185,000,000. The Bureau of Chemistry of the State Department of Agriculture in California reported during the fiscal year 1946-47 the registration of 7717 economic poisons. [Pg.53]

More information is available on the public health impact of occupational contact dermatitis. Specific national occupational disease and illness data are available from the U.S. Bureau of Labor Statistics (BLS), which conducts annual surveys of approximately 180,000 employers selected to represent all private industries in the United States.68 All occupational skin diseases or disorders, including allergic contact dermatitis, are tabulated in this survey. BLS data show that occupational skin diseases accounted for a consistent 30 to 45% of all cases of occupational illnesses from the 1970s through the mid-1980s, and in recent years accounted for 15% of all occupational illness.68 The decline in this proportion may be partially related to an increase seen in disorders associated with repeated trauma. [Pg.567]

In 1940 most of the shellac imported into the United States came in through the docks of Brooklyn. It was, therefore, appropriate that W. H. Gardner had selected the Polytechnic as the site to establish a national testing laboratory a few years before. Research at the laboratory, called the Shellac Bureau, centered on evaluating the properties of this important natural resin. On assuming his position in Brooklyn, Mark was assigned to the Shellac Bureau. [Pg.82]
