Gathered samples and conducted tests based on ASTM Standards D5603 and D5644. Task 4 Deliverables: DK Enterprises performed and prepared and produced sieve 204 sieve analysis reports between 2015 and 2018 and provided the results to the Contract Manager and to the tire-derived material (TDM) feedstock suppliers and the tire-derived product manufacturers from which collection of the sample particle sizes was extracted for purposes of testing using ASTM D5644 Ro-Tap Method (Mechanical Vibratory Sieve Shaker). NSL Analytical Test provided a report that included a sieve report representing two California tire- derived material suppliers and one manufacturer’s crumb rubber samples by using ASTM D5644 Ro-Tap Method and scanning electron microscopy (SEM) images. Laser diffraction was also performed to produce an overlay of the material.
