Low Temperature Pressure Impact Test Equipment
Low Temperature Pressure Impact Test Equipment information:
The specimens are subjected to an impact test by means of an apparatus as shown in figure 27.
Low Temperature Pressure Impact Test Equipment, 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 h.
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 (1 000 ± 2) g.
After the test, the specimen shall show no damage within the meaning of this standard.
Low Temperature Pressure Impact Test Equipment Technical parameters:
The height of falling: 10~250mm is adjustable.
