Government Specifications

Table 7.8, which gathers the French government specifications and test methods concerning hydrocarbon solvents, is divided into three parts ... 

If regulations governing specific emission limit VOC concentrations to the low ppm range then, of course, vapor fractions such as those illustrated by the above tabulation will not be acceptable. It may, however, still be justified to consider VOC condensation as a precursor to a final abatement device such as an adsorption bed. Removing most of the solvent from a vent stream by condensation, can drastically reduce the size and cost of a downstream cleanup system.

Steel. Steel shall conform to one of the applicable ASTM specifications referred to by applicable AISC specifications. Other steels not covered by these specifications may be used provided that the chemical and physical properties conform to the limits guaranteed by the steel manufacturer. Structural steel shapes having specified minimum yield less than 33,000 psi shall not be used. Certified mill test report or certified reports of tests made in accordance with ASTM A6 and the governing specification shall constitute evidence of conformity with one of the specifications listed. 

The most widely used accelerated tests are based on salt spray, and are covered by several Government Specifications. BS 1391 1952 (recently withdrawn) gives details of a hand-atomiser salt-spray test which employs synthetic sea-water and also of a sulphur-dioxide corrosion test. A continuous salt-spray test is described in ASTM B 117-61 and BS AU 148 Part 2(1969). Phosphate coatings are occasionally tested by continuous salt spray without a sealing oil film and are expected to withstand one or two hours spray without showing signs of rust the value of such a test in cases where sealing is normally undertaken is extremely doubtful. 

Another approach employed to establish the occurrence of a density nversion between the two solutions subsequent to boundary formation involves dialysis between the two solutions s0>. The dialysis membrane is impermeable to the polymer solutes but permeable to the micromolecular solvent, H20. Transfer of water across the membrane occurs until osmotic equilibrium involving equalization of water activity across the membrane is attained. Solutions equilibrated by dialysis would only undergo macroscopic density inversion at dextran concentrations above the critical concentration required for the rapid transport of PVP 36 0 50). The major difference between this type of experiment and that performed in free diffusion is that in the former only the effect of the specific solvent transport is seen which is equivalent to a density inversion occurring with respect to a membrane-fixed or solute-fixed frame of reference. Such restrictions are not imposed on free diffusion where equilibration involves transport of all components in a volume-fixed frame of reference. The solvent flow is governed specifically by the flow of the polymer solutes as described by Eq. (3) which, on rearrangement, gives... 

Contracts for acetylene-grade carbide are usually based on size and gas yidd specification, and indude penalties for carbide that fails to meet specified gas yidd. The sizes generally available in the trade are based on established U.S. Government specifications. In general gas yidds range from 280—300 L/kg and depend on the screen size of the carbide. The most important standard is the method of expressing gas yidd, which in the United States is at 15°C and 101 kPa (1 atm). Gas impurities are typically 0.05% by volume phosphine, 0.15% by volume hydrogen sulfide, and 0.001% arsine. 

Each facility must meet government specifications. 

Before there were laws in the United States for governing specifically the behavior of professionals, there were standards or codes of ethics established by professional guilds and associations. These codes of ethics stated in a formal way the type and level of professional performance that a professional association expected from its members. These expectations were derived from the... 

Paraformaldehyde is made by dehydrating common formaldehyde solution. Use caution because it is a known carcinogen. This method produces what is known as Type B RDX, which contains 8 to 12 percent HMX. Since HMX is slightly more powerful than RDX and has other useful explosive characteristics, no one gets too concerned about this "impurity." HMX is specifically mentioned in the government specifications for C-4. 

This was the forerunner of all modern NCNM priming compositions. With very few exceptions, U.S. commercial primers became noncorrosive about 1931 but because of stringent U.S. government specifications for military ammunitions, which could not be met by the earlier versions of the new... 

An adhesive or sealant specification, like all material specifications, is a document that specifies values for all the important properties, together with limits of variability and methods for determining these values. There are many adhesives and sealant specifications, of which the most prominent are the industrial and government specifications. These describe and establish the technical and physical characteristics or performance requirements of adhesive materials. The most common sources of standards and specifications for the adhesives and sealants industry are the following ... 

Relevant ASTM specifications and standards are presented in App. G. A variety of federal and military specifications describing adhesives and test methods have been prepared. Selected government specifications are also described in App. G. Table 19.4 identifies several other sources of specifications for adhesives, sealants, and related equipment.

A very important alloy containing 25 per cent, of nickel and 75 per cent, of copper finds extensive application in the manufacture of currency both in Europe and in the New World. Reference has already been made to this in previous pages.1 Monel metal is an alloy of nickel and copper made by the Orford Copper Company by direct reduction of the nickel-copper matte obtained from the Sudbury ores (see p. 82). It is therefore termed a natural alloy. It contains from 60-72 per cent, of nickel, the remainder consisting mainly of copper with iron ranging from 0-5 to 6-5 per cent. The United States Government specification, issued in July 1910, for monel metal requires 8...

Another phase of the management of HLW at NFS is to ensure that the composition does not exceed specifications. These specifications, shown in Table II along with the actual composition of the Purex wastes as of December 1973, include limits for 10 elements, two ions, excess caustic, heat value, and capacity. The governing specifications for the NFS Purex waste are 8.0M sodium plus potassium and the 600,000-gal operational volume of the storage tank. 

In this chapter the author has provided brief descriptions of the contents of some of the standards listed, but space did not permit such coverage on all standards. Additional information on industry and government specifications and standards and how they are used may be found in References 1 and 2.

Details of the GLPs and GLP inspections may be found on government-specific websites. Many are listed in the references below. Briefly, the FDA GLPs, define the scope of the regulation and have a detailed listing of definitions. If the FDA is to consider a nonclinical laboratory study in support of an application for a research or marketing permit, the testing facility, records and specimens must be available for inspection by an authorized employee of the FDA.

Likewise, there is a host of government specifications promulgated by the military agencies for plastic materials and products. These can be located by consulting the semiannual indexes issued by the Departments of the Army 37), Navy 30), and Air Force 20), and the Munitions Board 35).

These two types of questions are troublesome because, although most organizations have lists and indexes of their own material, there is no over-all list or index to standards. Standards are not, as a general rule, abstracted for abstract journals. There have been a few compilations of standards. One of these is the National Directory of Commodity Specifications issued by the National Bureau of Standards. Another is Circular 751 of the Scientific Section of the National Paint, Varnish, and Lacquer Association. This circular contains abstracts of all U. S. government specifications on paints, varnishes, lacquers, and their raw materials.
