3.4.2.1 - Toys with Translational Motion (walking, rolling, flying, etc)
3.4.2.1.1 - Determine the current draw described in the first bullet above (§3.4.2) through measurement. Use the worst-case foreseeable surface when making the measurement (e.g., carpet may be more unfavorable than tile in many instances).
3.4.2.1.2 - If the toy has a momentary function (such as an R/C with a conversion feature), determine a reasonable activation frequency for the feature and the additional current drawn by the feature. Add this current to that measured in §3.4.2.1.1 above by calculating the time-weighted average.
3.4.2.1.3 - Fixture the toy using rollers, conveyors, or other means such that it can be tested while stationary.
Note: The battery life of the toy while being tested in the fixture should be comparable to when it is played in a similar fashion on the floor (or other appropriate surface). If the battery life is considerably shorter, then test the toy per §3.4.2.1.5 instead.
3.4.2.1.4 - Verify that while being operated in the fixture, the toy draws the target current as measured in §3.4.2.1.1 (or §3.4.2.1.2 if applicable). It may be necessary to load down the toy to achieve this current.
3.4.2.1.5 - If the target current can not be achieved because the toy stalls before reaching it, remove the toy from the fixture and test it manually on the worst foreseeable surface as determined in §3.4.2.1.1. Make periodic temperature measurements with a fast-response surface temperature probe.
3.4.2.1.6 - Operation should be continuous if possible. If the toy shuts off automatically, it must be repeatedly reactivated.
