IEC60884 Fig27 Fig 42 Impact Test Apparatus On Pins Provided With Insulating Sleeves
Product information:
Confirms:
IEC 60884 Figure 27
The specimens are subjected to an impact test by means of an apparatus as shown in figure 27.
The apparatus, positioned on a pad of sponge rubber 40 mm thick, is placed together with the specimens in a freezer at a temperature of (–15 ± 2) °C, for at least 16 hours.
At the end of this period, each specimen, in turn, is placed in the normal position of use as shown in figure 27, and a weight is allowed to fall from a height of 100 mm. The mass of the falling weight is
(1000 ± 2) g.
After the test, the specimen shall show no damage within the meaning of this standard.
Confirms:
IEC 60884 Figure 42
The specimens are subjected to an impact test by means of the apparatus as shown in figure 42.
The mass of the falling weight is (100 ± 1) g.
The apparatus, on a sponge rubber pad, 40 mm thick, is placed, together with the specimens, in a
freezer at a temperature of (–15 ± 2) ℃ for at least 24 h.
At the end of this period, each specimen in turn, is placed in position, as shown in figure 42, and the
falling weight is allowed to fall from a height of 100 mm. Four impacts are applied successively to
the same specimen, rotating it through 90° between impacts.
After the test the specimens are allowed to attain approximately room temperature and are then
examined.
No cracks of the insulating sleeves shall be visible with normal or corrected vision without additional
magnification.
NOTE The cooling period of 24 h, mentioned in the tests of 30.3 and 30.4, includes the time necessary for cooling down the apparatus.
Technical parameters:
The height of falling: 10~250mm is adjustable.
