9.2 The requirement of 9.1 applies for all positions of the tool when it is operated as in normal use, even
after removal of detachable parts.
Lamps located behind a detachable cover are not removed, provided the tool can be isolated from the
supply by means of a plug or an all-pole switch. However, during insertion or removal of lamps which are
located behind a detachable cover, protection against contact with live parts of the lamp cap shall be
ensured.
This excludes the use of screw type fuses and screw-type miniature circuit breakers which are accessible
without the aid of a tool.
The test finger of Figure 1 is applied without appreciable force, the tool being in every possible position.
Through openings, the test finger is applied to any depth that the finger will permit, and it is rotated or
angled before, during, and after insertion to any position.
If the opening does not allow the entry of the finger, the force on the finger in the straight position is
increased to 20 N and the test with the finger bent repeated.
It shall not be possible to touch with the test finger live parts or live parts protected only by lacquer,
enamel, ordinary paper, cotton, oxide film, beads or sealing compound.
Lacquer, enamel, ordinary paper, cotton, oxide film on metal parts, beads and sealing compound, except
self-hardening resins, are not considered to give the required protection against contact with live parts.
9.3 For openings in class II tools or class II constructions, except for those giving access to lamp caps or
live parts in socket-outlets of class I tools, the test pin of Figure 2 is applied without appreciable force. It
shall not be possible to touch live parts with the test pin.
9.4 In addition, class II tools and class II constructions shall be so constructed and enclosed that there is
adequate protection against accidental contact with basic insulation, and metal parts separated from live
