Flaw. A flaw can be defined as an imperfection in a material that does not affect its usefulness or serviceability. A component may have imperfections and still retain its usefulness. This fact is recognized by most material codes that permit, but limit, the size and extent of imperfections. This is particularly true of welds, which commonly contain harmless imperfections. It is not uncommon for failures to occur in the vicinity of flaws that have contributed nothing to the failure mode.

The usual complete line designation contains the following (1) line size (nominal) (2) material code (3) sequence number and (4) materials of construction. 

Figure 4-164 shows a steel body core bit with a long-taper, stepped profile fitted with impregnated natural diamond blocks as the primary cutting elements. The bit has no inner cone. Since there is no specific code for the natural diamond/steel body combination, the letter O (other) is used as the cutter type/ body material code. The profile code 3 is used to describe the long outer taper with little or no inner cone depth. The hydraulic design code 5 indicates a fixed... 

Figure 1 shows a flow chart for part of a recursive modelling procedure, illustrated in this paper, which accepts as input a formula consisting of constituent raw material codes or formula names, and quantities. The procedure retrieves property data for each raw material in order to perform the required calculations. When the procedure encounters a constituent that is a formulated product, it calls itself using that product as input. The output of the procedure consists of the calculated properties of the formula, including those properties of the formula that would be retrieved from data files for non-formulated or purchased raw materials. By returning this latter set of properties, the procedure can treat formulas as raw materials. 

The appendix shows an example of a recursive procedure to calculate the pigment to binder ratio for a non-reactive coating formulation. We assume that a raw material data base contains raw material code, density, cost per unit weight, solids volume fraction, and pigment solids volume fraction. Formulas are stored in files that contain the identification and amount of... 

Imagine wanting to construct a list of all raw materials involved in a formula containing formulated intermediates. Such a list is a pair of arrays showing all basic raw material codes and amounts. For instance, if a formula contains components A and B, where B is a raw material and A is a formulated intermediate containing raw materials X, Y and Z, then the list would contain data for X, Y, Z and B. 

The toxic and harmful degree bears code 6, the highly toxic degree, code 66. For corrosive materials, codes will be 8 and 88. if there is no secondary code, the minimum degree of danger will bear the figures 60 and 80 respectively. These codes appear at the rear of vehicles and on packaging.

Plastic pipe or tubing may be used for a wide variety of services. As with all nonmetallic materials, code restrictions limit the applications in which their use is permitted. In general, their use in flammable or toxic service is limited. Plastic tubing of various types may be used for instrument air-signal connections however, as is the case with all nonmetallic applications, the need for fire resistance must be considered. When used)in specialized applications such as potable water or underground fire water, care should be taken to ensure that the specified products are certified by appropriate agencies such as the National Sanitation Foundation and Factory Mutual. 

Commercial use of ethanol fuel is regulated by NFPA 30, Flammable and Combustible Material Code. For ethanol storage and dispensing systems, the NFPA 30A, Automotive and Marine Service Station Code, would apply. 

The field of DNA vaccines centers on the ability to deliver genetic material, coding, for desired protein antigens in the context of a mammalian expression vector (Donnelly et al., 1997). It was realized that the immunostimulatory properties observed with DNA vaccines, namely the ability to induce a Thl biased or cell mediated immune response, was attributable in part to the presence of CpG motifs within the plasmid DNA (Klinman et al., 1997). In fact, it was demonstrated that the quality of immune activation by DNA vaccines could be influenced by the deliber-ate alteration of CpG content (Krieg et al., 1998). Further, with the identification of neutralizing CpG motifs it became possible to remove any neutralizing influence from the DNA vaccine plasmids. The end result was the optimization of DNA vaccine plasmids, with respect to immune activation (Krieg et al., 1998).
