Standard for the uniform

The first set of "Standards for the uniform supply and testing of Portland cement" in Germany were issued in 1878. It was the first German Standard relating to a material (and a mass product). The two Portland blastfurnace cements, "Eisenportland" and "Hochofen", were standardized in 1909 and 1917 respectively. [Pg.469]

Finally, the safety of high-pressure plants is of outstanding importance. Thus, in the course of development, national safety rules for vessels, pipes, and valves have been introduced by special organizations. For example, in 1884, the American Society of Mechanical Engineering (ASME) launched its first standard for the uniformity of testing methods of boilers. The German society TUV was founded in 1869 in order to avoid the devastating explosions of steam vessels. [Pg.3]

The Standard for the Uniform Scheduling of Drugs and Poisons provides for mandatory warning labelling of containers when certain scheduled substances have been added to the cosmetic. [Pg.20]

Defining a Stem layer using hydrated radii of the ions is justified in the P—B framework, since ions must be fully hydrated in order for the uniform dielectric approximation to be valid. If ions were allowed to penetrate this layer, then additional physics would have to be introduced to account for ion—ion correlations, partial dehydration, and other considerations that fall well outside the realm of applicability for standard continuum solvent models. To generalize the P—B framework, new approaches are needed... [Pg.429]

This chapter will focus on some, but not all, of the areas in which the U.S. Food and Drug Administration (FDA) and the European Union (EU) regulatory authorities have attempted to coordinate their efforts to provide uniform rules and standards for the pharmaceutical industry. Specifically, we will review the efforts to harmonize approaches relating to inspections (including public disclosure of confidential information) and product approval or authorization (including clinical trials). While space limitations do not provide sufficient opportunity to describe each regulatory authority s system or the harmonization attempts in detail, it is our hope to provide some background of where the efforts are now, where the efforts are intended to go, and what we believe will be the results of these efforts. In addition, the author is much more familiar with the U.S. system than the EU system because of his experience and daily exposure with FDA, this chapter will focus more on the U.S. structure. [Pg.553]

The pH accordingly acquires primary importance as an index of the state of the many interactive acid-base systems of which seawater is composed. Two factors are essential to the most fruitful application of this acid-base parameter. The first is that pH measurements possess reproducibility of a high order, and the second is that the numbers obtained have a clear meaning in terms of the processes of interest. To achieve the necessary reproducibility, uniform procedures and standards for the measurement must be accepted by all workers in the field. [Pg.110]

Emergent Stem Correction for Mercuiy-in-glass Thermometers.—k large proportion of the thermometers now sold are graduated and standardized for the condition of total immersion, that is, for the condition that the bulb and all the portions of the stem which contain mercury, are heated to a uniform temperature. [Pg.414]

In a similar fashion, one can see the extension of the tighter regulations as they apply in the United States, to Japan and Western Europe. Through the EU, they have implemented similar standards for the very same reason in Europe additionally, many of the third world nations have already implemented their own GMP initiatives reemphasizing the growing uniformity in such requirements throughout the world. [Pg.6]

However, biomedical polymer is an interdisciplinary subject and has varying types of classification based on different purposes and practices. For example, it can be categorized based on the source and application purpose of the medical polymer or based on the influence of living tissues to the materials. Presently there is no uniform standard for the classification. [Pg.166]

After the benchmarks are established, they are then arranged in decreasing order (from shortest to longest time). If there are 20 slots, and if a uniform distribution is used, the time standard for the first slot (UlLS one) is computed by calculating the mean of the first 10 benchmark standards. Similarly, the value of UlLS two is taken by the mean of benchmark standards 11-20. Succeeding UlLS slots will be calculated on the successive 10 benchmark standards. Hence, the UlLS 20 would be equal to the mean of benchmark standards 191 through 200. Engineers have used this procedure extensively in the development of UlLS. [Pg.1460]

Characteristic of integrated process chains is a common database in the form of an integrated product model that contains a uniform information structure. The information structure must be able to present in a model all relevant product data in the process chain and to portray the model with the use of a homogenous mechanism. A corresponding basis for the realization of such information models is offered by the Standard for the Exchange of Product Model Data (ISO 10303—STEP) (ISO 1994). [Pg.2852]

These values have been available for a long time in tabular form. Nevertheless it is advisable to produce one s own calibration standards for the specific analytical conditions, as the surface structure, the residue material and the uniformity or otherwise of its... [Pg.472]

Uniform cotton standards were established in 1907 by international representatives from the cotton industry (United States Department of Agriculture 1995). The US Cotton Standards Act of 4 March 1923, authorized the Secretary of Agriculture to establish standards for the classification of cotton by which its quality could be... [Pg.78]

In addition to vinylsilanes, ATH- and MDH-filled ethylene vinylacetate copolymers can be effectively coupled to aminosilanes [37]. Fine and uniform ATH dispersion in the polymer leads to low H FFR compound viscosities (M FI) and high tear strength. The use of 3-aminopropyltriethoxysilane became an industrial standard for the production of reliable thermoplastic HFFR compounds. New primary/secondary aminosilane blends provide further improvements in the final HFFR compound [38]. Aminosilanes are also found in thermoplastic EVA, nonperoxide cross-linked. [Pg.83]
