Application temperature range

The applicable temperature range is lower than that of Reaction (1), 600-1000°C, but free boron tends to be incorporated in the deposit below 650°C.h°] ZrB2 is deposited by a similar reaction. ]... 

During application, temperatures ranged from 17 to 27°C and from 16 to 28°C for the work clothing and protective clothing trials, respectively. During harvesting, temperature ranges were 19 to 26°C and 15 to 25°C for both exposure scenarios. 

Suitable conversion tables are available (ASTM D341), and each table or chart is constructed such that for any given petroleum or petroleum product, the viscosity-temperature points result in a straight line over the applicable temperature range. Thus, only two viscosity measurements need be made at temperatures far enough apart to determine a line on the appropriate chart from which the approximate viscosity at any other temperature can be read. 

Given the Arrhenius equation for a reaction, i.e., given the preexponential factor A and the activation energy E as well as the applicable temperature range, k can be found at any temperature within the range. The calculation is not complicated but one must (i) maintain consistency between units, and (ii) be especially careful about the unit of temperature (which must be converted to kelvins).

Values of A, B, and C are tabulated for a number of materials. The applicable temperature range is not large and in most situations corresponds to a pressure interval of about 0.001-2 bar. The Antoine equation should never be used outside the stated temperature limits, since extrapolations beyond these limits may lead to absurd results. The constants A, B, and C form a set. It is recommended never to use one constant from one tabulation and other constants from different tabulation. Usually, in the... 

Anomalous viscosity in residual fuel oils is best shown by plotting the kinematic viscosity determined at the normal test temperature and at two or three higher temperatures on viscosity-temperature charts (ASTM D-341). These charts are constructed so that, for a Newtonian fuel oil, the temperature-viscosity relationship is linear. Nonlinearity at the lower end of the applicable temperature range is normally considered evidence of non-Newtonian behavior. The charts are also useful for the estimation of the viscosity of a fuel oil blend from knowledge of the component viscosities and for calculation of the preheat temperature necessary to obtain the required viscosity for efficient atomization of the fuel oil in the burner. 

The source does not contain original experimental data. The rating provided and applicable temperature range estimates are based on auxiliary information. 

The applicable temperature range is determined from the graphical representation reported in the original source. 

Table 1 lists all the reactions studied and gives the recommended rate constant k for every bimolecular reaction, as well as the applicable temperature range and the associated error limits. Where more than one set of products is possible, rate constants or branching ratios are given for all channels considered feasible. The data for decomposition reactions and combination reactions are given in Tables 2 and 3, respectively. The reference includes a detailed data sheet for each reaction listed here, covering the thermodynamic data, kinetic measurements, and reliability assessments. 

A basic property is the melting temperature since it is known that materials parameters which characterize the deformation behavior are well correlated with the melting temperature (Frost and Ashby, 1982). Examples are the elastic moduli which not only control the elastic deformation, but are also important parameters for describing the plastic deformation, and the diffusion coefficients which control not only the kinetics of phase reactions, but also the kinetics of high-temperature deformation, i.e. creep. Furthermore, the melting temperature is intuitively regarded as a measure of the phase stability since it limits the application temperature range. 

Ye and co-workers exploited the shear stability of highly branched, high molecular weight polyethylenes (PEs) as lubricant viscosity index improvers [252, 253]. Viscosity index of a lubricant is a critical parameter which defines its quality and application temperature range. They synthesized PEs with controllable chain topologies ranging from linear to a hyperbranched dendritic structure by chain walking polymerization [254]. The PE samples were blended into a base paraffinic oil (density 0.8659 g mL at 15 °C, kinematic viscosity 30.06 cST at 40 °C) to form lubricants. The lubricants were subjected to the Kurt Orbahn (KO) test to measure the shear stability index, which is expressed by... 

In contrast, the use of thicker and less-dense textile structures leads to a delayed and therefore more efficient heat release of the PCM. Furthermore, the phase change temperature range and the application temperature range should correspond in order to realize the desired thermal benefits.

Stabilizers, or more precisely antioxidants, are used to capture radicals in the system and thereby inhibit the degradation process. Mostly O-radicals are captured, but there are also some developments towards capturing C-radicals. Primary types (e.g. phosphites) mainly show activity in processing (melt temperature), secondary types (e.g. sterically hindered phenolics) in the normal application temperature range (long term stabilizers). Ultraviolet stabilizers are an additional means of preserving material properties by inhibition of the primary radical creation through radiation. 

A number of heat flow rate calibration materials have also been suggested for the calibration of the heat capacity scale of calorimeters. Table 9.2 describes these materials and the applicable temperature ranges.
