IEC60068-2-75 Impact Testing Machine Striking Element IK Level Test IK10
Test to verify the protection against mechanical impacts:
In order to verify the protection against mechanical impacts, blows
shall be applied to the enclosure to be tested.
The test shall be done by using one of the test apparatus described
in IEC 60068-2-75.
The relevant product standard shall specify which types of test
apparatus are appropriate.
During the test the enclosure shall be mounted on a rigid support,
according to the manufacturer’s instructions for use. A support is
considered to be sufficiently rigid if its displacement is less
than or equal to 0,1 mm under the effect of an impact directly
applied and whose energy corresponds to the degree of protection.
Alternative mounting and support, suitable for the product, may be
specified in the relevant product standard.
Impact Testing Machine
The number of impacts shall be five on each exposed face unless
otherwise specified in the relevant product standard. The impacts
shall be evenly distributed on the faces of the enclosure(s) under
test. In no case shall more than three impacts be applied in the
surroundings of the same point of the enclosure. The relevant
product standard shall specify the points of application of
impacts.
