ASTM International’s recovered carbon black (rCB) committee (D36) is developing a proposed standard for differentiating between various rCB products and providing quality control tool for producers and users. According to ATSM International member Pieter ter Haar, the voluntary consensus standards developer and implementer’s proposed WK81244 standard will aid the adoption of recovered carbon black produced from end-of-life tyres.
