Classification group

As shown here, the method used to determine a films quality is similar in each standard, but the classification groups are not harmonized. This is unfortunate, but there is no reason that this cannot be... 

The range of colors covers all hue classification groups except a tme red. As a rule, the hues are dull compared with other dye classes. Black is the most important, followed by blues, oHves, and browns (see Dyes and dye intermediates). 

Table 7-3 provides a comparison between historical and alternative approaches for identifying electrical classification groups. Table 7-4 compares NEC Division and Zone Classification Systems. 

The composition of the extraction liquid is very important for the magnitude of the partition coefficient of a solute. Several quantities have been studied to describe solvent properties. Snyder [20,21] grouped the relative selectivity of solvents into solvent selectivity classification groups, each group formed according to proton donating, proton accepting and dipole interaction properties. 

Meyer (Ref 3) states that Unigex is the trade name of a semigelatinous permitted expl distributed in the UJC. by I.C.I., belonging to Brit classification group P3, with a d of 1.35g/cc and a wt strength of 47%... 

From the six classifications described above may be worked out a single mixed classification which is useful in military operations. This mixed or miliiary classification groups all chemical agents into categories most useful to the using troops. 

The models most frequently used to describe the concentration dependence of diffusion and permeability coefficients of gases and vapors, including hydrocarbons, are transport model of dual-mode sorption (which is usually used to describe diffusion and permeation in polymer glasses) as well as its various modifications molecular models analyzing the relation of diffusion coefficients to the movement of penetrant molecules and the effect of intermolecular forces on these processes and free volume models describing the relation of diffusion coefficients and fractional free volume of the system. Molecular models and free volume models are commonly used to describe diffusion in rubbery polymers. However, some versions of these models that fall into both classification groups have been used for both mbbery and glassy polymers. These are the models by Pace-Datyner and Duda-Vrentas [7,29,30]. 

Therefore, it is placed in the International Agency for Research on Cancer (lARC) classification Group 3.
