The last two characters are assigned arbitrarily. Generally, the series blacks have the smallest primary particle sizes. Please first verify your email before subscribing to alerts. Your Alert Profile lists the documents that will be monitored. D — 03 Standard Classi? In general, Test Method D can be used to estimate the surface area of furnace blacks but not channel, oxidized, and thermal blacks. As the voice of the U. Some commonly used names are:.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. The last two characters are assigned arbitrarily. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. The use of inactive or unassigned N or S designations is prohibited until such a time as the designation is officially reactivated or assigned by Subcommittee D See also Terminology D The first character gives some indication of the influence of the carbon black on the rate of cure of a typical rubber compound containing the black.
Standards Subscriptions r1765 ANSI provides a money-saving, multi-user solution for accessing standards.
The moment new editions of the standards you adtm are released, changes are made, or appendixes are published, you will be alerted by email. Before the ASTM nomenclature was introduced, people used to and still do designate blacks after their application type.
The second character gives information on the average surface area of the carbon black. This standard is also available to be included in Standards Subscriptions.
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. Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. In practice, the black compounds shall be mixed and tested at the same time using the formulation in Test Methods D Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
All other properties shown are averages of typical values supplied by several manufacturers. The series blacks have very large primary particles: The following two digits were chosen randomly and do not have a specific meaning. In EPDM, which does not possess a high intrinsic plasticity, these types of black can hardly be incorporated and dispersed. We have no document history for this standard. This service is not available if you are a URL user where you do not log in with an email address.
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. The second character gives information on the average surface area of the carbon black.
This ensures that you are always up-to-date and saves you both time and money. Typical values often vary between suppliers; therefore, the range of data used to de?
ASTM classification numbers “N” or “S” designation not d165 in have either been withdrawn or are not currently assigned. 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.
On the other hand, these blacks are quite difficult to incorporate in the rubber, because of the high shear forces needed for the dispersion.
ASTM D – 04 Standard Classification System for Carbon Blacks Used in Rubber Products
The first character gives some indication of the influence of the carbon black on the rate of cure of a typical rubber compound containing the black. 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 sstm property values in that laboratory.
In general, Test Method D can be used to estimate the surface area of furnace blacks but no channel, oxidized and thermal blacks. The second character gives information on the average surface area of the carbon black.
ASTM D – 18 Standard Classification System for Carbon Blacks Used in Rubber Products
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. Webprint Printed and bound. The benefits of a subscription: Standards monitoring is a d17655 service designed for you who wish to be alerted dd1765 changes to or new editions of the standards required in your work.
A nomenclature was set up, consisting of a letter and three digits: A target value is defined as an agreed upon value on which producers center their production process and users center their specifications. These groups are as follows:
