falling drops of water must not give undesirable effects. |
2 |
against
the foreign bodies with average sizes
 |
Protecting
of man against a casual contact fingers with active or internal
moving parts. Protecting of object against penetration of hard foreign
objects with size more than 12 mm. |

against
water, falling apeak under a corner no more than 15 degrees
 |
Drops
of water, falling under a corner no more than 15 degrees to the
vertical line, must not give undesirable effects. |
3 |
against
small foreign bodies
 |
Protecting of man against
contiguity of instrument, wires or similar objects with active
or internal moving parts. Protecting of object against penetration
of hard foreign objects with size more than 2.5 mm.
