ASTM develops faster testing standard for recovered carbon black
ASTM International’s recovered carbon black (rCB) committee (D36) is advancing work on a new standard that could greatly improve production process monitoring and productivity for rCB manufacturers. The proposed method, known as WK91069, is being developed within the committee’s recovered carbon black subcommittee (D36.10). According to ASTM member Pieter ter Haar, director of rCB at Circtec, the standard addresses one of the industry’s key challenges: long testing times.
