IEC 60320-1 Figure 20 Apparatus for Pressure Test on Shrouds
Th apparatus for pressure test on shrouds is manfactured according to the IEC60320-1 clause 23.4 and figure 20.
It is used for testing the mechanical strength of surface-mounted applianceinlets having a shroud of metal.
Appliance inlets designed for surface mounting and having a shroud of metal, are compressed in an appropriate test apparatus, an example of which is shown in figure 20. The spherical end of the jaws shall have a radius of 20 mm ± 1 mm. A force of 40 N ± 2 N shall be applied for 60 s ± 6 s through the jaws to the most unfavourable point half-way up the outer surface of the shroud, in a direction perpendicular to the axis of the shroud. After the test, there shall be no deformation or loosening of the shroud such as will impair the further use of the appliance inlet.
