– IPX7 tools are subjected to the test described in 14.2.7.
For this last test, the tool is immersed in water containing 1 % NaCl.
Immediately after the appropriate treatment, the tool shall withstand the electric strength test of clause 15,
and inspection shall show that there is no trace of water on insulation which could result in a reduction of
creepage distances and clearances below the values specified in 28.1.
Tools which are not subject to spillage of liquid in normal use are allowed to stand in normal test-room
atmosphere for 24 h before being subjected to the test of 14.3.
14.2 Tools subject to spillage of liquid in normal use shall be so constructed that such spillage does not
affect their electrical insulation.
Compliance is checked by the following test.
Tools incorporating an appliance inlet are fitted with an appropriate connector and flexible cord; tools with
type X attachment are fitted with the lightest permissible type of flexible cord of the smallest
cross-sectional area specified in 25.2; other tools are tested as delivered.
Electrical components, covers and other parts which can be removed without the aid of a tool are
removed, except those fulfilling the test of 21.23.
The liquid container of the tool is completely filled with water containing approximately 1 % NaCl, and a
further quantity, equal to 15 % of the capacity of the container, or 0,25 l, whichever is the greater, is
poured in steadily over a period of 1 min.
Immediately after this treatment, the tool shall withstand an electric strength test as specified in clause 15,
and inspection shall show that there is no trace of water on insulation which could result in a reduction of
creepage distances and clearances below the values specified in 28.1.
The tool is allowed to stand in normal test-room atmosphere for 24 h before being subjected to the test
of 14.3.
