Standard Classification System for Carbon Blacks Used in Rubber Products

D — 03 Standard Classi? A number in parentheses d7165 the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. The second character gives information on the average surface area of the carbon black. The last two characters are assigned arbitrarily.

The values given in parentheses are for information only.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Current edition approved Jan. Originally approved in Last previous edition approved in as D — 01e1. Channel blacks characteristically impart a slower rate of cure to rubber compounds.

A target value is de?

All other properties shown are averages of typical values supplied by several manufacturers. 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.

ASTM D – Standard Classification System for Carbon Blacks Used in Rubber Products

In general, Test Method D can be used to estimate the surface area of furnace blacks but not channel, oxidized, and thermal blacks. The surface area range of the carbon blacks has been divided into ten arbitrary groups, and each has been assigned a digit to describe that group.

These groups are as follows: Typical values often vary between suppliers; therefore, the range of data used to de? These ranges in no way should be viewed as being related to speci? Procedures for Classifying a New Carbon Black 5.

Typical Properties of Carbon Blacks 4. In practice, the black compounds shall be mixed and tested at the same time using the formulation in Test Methods D A large volume kg lb of this carbon black was prepared since it is used daily as a standard reference material by carbon black producers.

The carbon black has an iodine number of These table values may change slightly when the sample results taken over a longer period are pooled. The requestor of a new standard grade may pursue a revision of the table values by letter ballot during the?

Changes to the table after the? This spans a period of 20 years. Since the purpose of an Industry Reference Black is the elimination of the major part of laboratory-to-laboratory variation, it is used as a reference material within each laboratory to correct actual measured property values in that laboratory. Such an addition is likely to produce spurious results due to additive errors.

Consequently, any grade of carbon black produced at target values may deviate from the documented typical value.

Carbon blacks with data from a single producer are not included.
