UL 507 Electric Fans
8.2.5 Conventional designs of impellers meet the requirement of being guarded when:
a) The relationship between mass (W) in kg, radius (r) in mm, and speed (N) in revolutions per minute is such that K in the following equation is less than 29264:
K = 6 × 10 −7 (Wr 2 N 2 )
b) The guarding is such that the probe illustrated in Figure 8.1 cannot touch the leading edge of the blade and hub when inserted as described in 8.2.6. For a reversible fan, both edges of the blade are considered leading edges. When K is greater than 29264, the probe shall not touch any part of the impeller.
8.2.6 The portion of an impeller that entails a risk of injury to persons shall be guarded so that the probe illustrated in Figure 8.1 does not touch the part when inserted with a force of 4.45 N (1 pound) for a maximum of 5 seconds through any opening in the guard
