Standard Test Method for Rubber Compounding Materials—Determination of Particle Size Distribution of Recycled Vulcanizate Particulate Rubber

Importancia y uso:

4.1 The particulate size distribution of vulcanizate particulate rubber is used for the purpose of assigning a product mesh or average particle size designation.

4.2 The product designation for mesh size for the Ro-tap method is based on the size designation screen which allows a range for the upper limit retained of maximum 5 % for up to 850 μm (20 mesh) particles, maximum 10 % for 850 to 150 μm (20 to 100 mesh), and maximum 15 % for 125 to 20 μm (120 to 635 mesh). No rubber particles shall be retained on the zero screen (see Table 2, Classification D5603).

4.3 The weight percent retained on a specific screen is noted.
