A conduit run is installed from the ER to a TR. It has two (2) 90 degree bend and a length of 20 m (65 ft). What will be the MINIMUM test rating of the pull cord left in the conduit?

For a conduit run with two 90-degree bends and a length of 20 meters (65 feet), the minimum test rating for the pull cord left in the conduit should be 90 kg (200 lb). This ensures the pull cord can handle the tension and force required to pull cables through the conduit without breaking, especially given the bends and length of the run.
TDMM page 12-40 (page 1025) Provide a plastic or nylon line with a minimum test rating of ~90 kg (200lb) pulling tension in all entrance conduits.
