1 The water level is given as the clearance from the cuff of the glove to the water line, with a tolerance of 卤13 mm. (卤0.5 in.).
2 If atmospheric conditions make the specified clearances impractical, the clearances may be increased by a maximum of 25
mm. (1 in.).

1 The maximum use voltage is the a-c voltage (rms) classification of the protective equipment that designates the maximum
nominal design voltage of the energized system that may be safely worked. The nominal design voltage is equal to the phase-to-
phase voltage on multiphase circuits. However, the phase-to-ground potential is considered to be the nominal design voltage:
(1) If there is no multiphase exposure in a system area and if the voltage exposure is limited to the phase-to-ground potential,
or
(2) If the electrical equipment and devices are insulated or isolated or both so that the multiphase exposure on a grounded
wye circuit is removed.
2 The proof-test voltage shall be applied continuously for at least 1 minute, but no more than 3 minutes.
