WEST CONSHOHOCKEN, Pa.—ASTM International members from its committee on recovered carbon black announced new standards and are seeking input on those and related efforts, and several subcommittees are supporting the activities to help the tire recycling industry.
A subcommittee (D36.10) recently approved a list of 22 existing standards that already are being used in the carbon black industry, according to an ASTM statement. The group now will recognize the standards as acceptable for use in the rCB industry until rCB statistical data is available that may suggest otherwise. The complete list can be found at the ASTM website.
The subcommittee on co-products (D36.20) is soliciting laboratories to participate in a round robin study on rubber-derived liquids. In the study, several existing test methods will be used to verify their reliability for those liquids.
A task group within the subcommittee on environmental safety and sustainability (D36.40) has been formed to explore areas of standardization for polycyclic aromatic hydrocarbons in tires. The task group will hold its initial meeting in conjunction with the conference of the European Tyre Recycling Association in Brussels, Belgium, on March 14.
