VIBRATION TEST APPARATUS- AS PER IS 3144

Compliance With Following International Standards:

IS 3144-1992

Salient Features:

1. “EIE Vibration test” is designed to obtain Vibration test methods are given for evaluating the settlement of thermal insulation materials. Like, Rockwool, glass wool, etc....
2. Vibration at high frequency with small amplitude.
3. These have been used mainly for assessing the behavior of mineral wool and granular products for transport service.
4. A wooden box with smooth interior surfaces, having internal dimensions of 900 mm height, 600 mm length and 300 mm width provided with removable lid shall be secured within a steel frame work fixed to a steel base plate.
5. The box may be conveniently adapted for testing one or more specimens less than 300 mm thick by providing detachable vertical wooden partition 900 mm high by 600 mm long and 12 mm thick at required spacing having suitable fixing arrangements such as proper clamps, to provide uniform constant pressure on the vertical partition pressing the test sample.
6. Provision is made for vibrating the base plate in vertical plane at a frequency of about 24 Hz.
7. With which amplitude of approximately 1 mm about the mean position is obtained.
