IEC60335-2-2-clause 21.101 Current-carrying hoses crushing tester | Current-carrying hoses resistant to crushing
IEC60335-2-2-21 .101 Current-carrying hoses shall be resistant to crushing.
Compliance is checked by the following test.
The hose is placed between two parallel steel plates each having a length of 100 mm, a width
of 50 mm and the edges of the longer sides rounded with a radius of 1 mm. The axis of the
hose is positioned at right angles to the longer sides of the plates. The plates are placed at a
distance of approximately 350 mm from one end of the hose.
The steel plates are pressed together at a rate of 50 mm/min ± 5 mm/min until the applied
force is 1,5 kN. The force is then released and the electric strength test of 16.3 is carried out
between the conductors connected together and the saline solution.
