Classify the Source of Recycled Rubber Classification by Particle Size Particle size distribution is further identified by the range of sizes of the particulate material. The size reduced tire-derived material (TDM) and non TDM particle size designation portion of the classification is based on Test Method D5644-18, which is used to determine the particle size distribution. Table 2 Table 2 is designed to assist in the classification of recycled rubber that has been reduced in size to a limited size and is divided into two sections: 1. Table 2A Coarse sizes to a maximum of 1mm (18 mesh) 2. Table 2B Material sizes smaller than 1 mm (18 mesh) Table 2 Copyright ASTM International, 100 Barr Harbor Drive, West Conshohocken, PA 19428.
