The great variety of blacks requires a classification, in order to realize a possible interchangeability between the different suppliers. The second character gives information on the average surface area of the carbon black. The type of black that suits best to a particular rubber depends on the one hand on the application and on the other hand also on the intrinsic plasticity of the type of rubber. Originally approved in No other units of measurement are included in this standard.
The values given in parentheses are for information only. In practice, the black compounds shall be mixed and tested at the same time using the formulation in Test Methods D Generally, the series blacks have the smallest primary particle sizes.

All other properties shown are averages of typical values supplied by several manufacturers. The following two digits were chosen randomly and do not have a specific meaning.
Typical properties are dependent upon the target values and may vary from producer to producer at the same iodine adsorption and DBP absorption numbers because of the differences in processing equipment.
