Production tolerances

This provision will also account for any diminishing variation in C, as may be caused by ambient temperature, production tolerances or failure of a few capacitor elements or even of a few units during operation. 

Variation is an obvious measure for quality of conformance, but it must be associated with the requirements set by the specification to be of value at the design stage. Unfortunately, difficulty exists in finding the exact relationship between product tolerance and variability. Approximate relationships can be found by using process capability indices, quality metrics which are interrelated with manufacturing cost and tolerance (Lin et al., 1997). ...

These SPI tables can also be used as the basis for establishing standards for molded products between the designer, molder, and customer. Users will find that two separate sets of values are represented. Commercial values represent common production tolerances that can be achieved at the most economical level. Fine values represent closer tolerances that can be held, but at a greater cost. The selection of one or the other will depend on the application under consideration and the economics involved. 

A pressure control does not always shorten the MD, as can be read frequently. The pressure control adjusts a desired 7"jcc. If Tict. without pressure control is larger than with pressure control (as in this example) MD, would only decrease when the run would have been operated at 0.7 mbar (if the product tolerates the increased TKt. 

Biocatalysts able to expand the substrate usage spectrum of microorganisms (e.g., C5-sugars) and to increase tolerance to industrial conditions (e.g., high product tolerance, fast growth, high yield and productivity).

Figure 21 and Table 3 summarize the necessary DC-sources applied to the structures of the chip. Presently all DC-sources are programmable and variable in the range of-230 to +230 V. This flexibility is essential to determine the optimal parameter setting during system optimization. Once it is known many of these sources can be replaced by fixed ones. Still, due to production tolerances and long term drift effects the sources for ion extraction and focus (t/IFO), energy filter (Usl, Uso), and MCP (UHV) will have to remain variable for optimum device performance. 

All production methods involve inherent production tolerances that must be ensured by the application of respectively larger clearances.

Tolerance The amount of a chemical substance legally permitted in food products tolerance limits are established through formal regulatory procedures—for instance, permissible residue levels for pesticides in raw agricultural produce and processed foods. The use of products with no indication of tolerance values is considered illegal... 

The tests are again useful and have permitted the development of sophisticated fuzes for advanced military and aerospace systems. For limited-production items success may always be achieved by overdesign mass production tolerates a certain dud rate, and quality assurance may often be based on no more than the subjective assessment of whether or not a component goes bang at a customary level. 

When the substrate and oxidized product tolerate hydrolytic conditions, the oxidation can be performed in situ. For this purpose we have found it advantageous to employ 2-butanone [5] instead of acetone as source of the dioxirane. Because of its partial solubility in water and excellent solvent properties no cosolvents such as CH2C12 or C6H6 are required. For convenience, in Table 2, we have summarized the reaction conditions and variables used for the dioxirane oxidations in the isolated and in situ modes. 

Parts, with a mount density of 4300 g/m in a 4.25 mm nominal gap, were canned for the 1.6 CVH engine. They were run on the High Speed Dyno test, and after 60 cycles, they showed more erosion than 4070 g/m in a 4.25 mm gap. For both parts, a 2 cm width of the mat had been eroded in the flat section for the entire length of the substrate, on the same side as the heat shield. This most unexpected observation was explained by the wide production tolerance in the manufacture of mat of 8%. Although the overall roll is labeled 4300 g/m, the density of the parts tested could have been as low as 3956 g/m or as high as 4644 g/m. ...
