Testing of industrial filament yarns made from man-made organic base fibers may be performed in accordance with ASTM D885. These test methods cover the testing of industrial filament yarns made wholly of manufactured organic-base fibers, cords twisted from such yarns, fabrics woven from such cords, and products that are made specifically for use in the manufacture of pneumatic tires. They may be applied to similar yarns and cords used for reinforcing other rubber goods and for other industrial applications. The material to be tested may be composed of nylon, polyester, rayon, and aramid and may be in the form of yarn, tire cords twisted from this yarn, and fabrics made from these tire cords. The methods include testing procedure only and include no specifications or tolerances.
