IS 10080:1982 is the Indian Standard (BIS) for vibration machine for standard cement mortar cubes. This standard specifies the requirements for the design, construction, and performance of a vibration machine. This machine is used to compact standard 70.6 mm cement mortar cubes for determining their compressive strength as per IS 4031.

! Ensure the machine is mounted on a rigid, level concrete foundation to prevent loss of vibration and ensure consistent compaction.
! The frequency of vibration should be periodically verified using a calibrated tachometer, as it is a critical parameter for achieving standard compaction.
! The gap between the hopper and the top of the mould must be properly maintained to avoid mortar leakage during vibration.

Key Differences
≠The fundamental compaction mechanism is different. IS 10080 specifies a high-frequency (200 Hz) 'vibration machine', whereas EN 196-1 and ISO 679 specify a low-frequency (1 Hz) 'jolting apparatus' that compacts the mortar by repeatedly dropping the mould from a fixed height.
≠The standard specimen geometry is different. IS 10080 is for 70.6 mm cubes, whereas the EN/ISO standards use 40 mm x 40 mm x 160 mm prisms, which are then broken in flexure and the halves tested in compression.
≠The operating frequency and displacement are vastly different. IS 10080 requires 12000 ± 400 vibrations per minute with a small amplitude, while EN 196-1 requires 60 'jolts' per minute with a drop height of 15.0 ± 0.3 mm.
≠The mass of the moving parts is defined differently. IS 10080 specifies a mass of 20 ± 0.5 kg for the moving parts including the mould, while EN 196-1 specifies a mass of 13.5 ± 0.5 kg for the moving parts of the table *excluding* the mould and sample.
Key Similarities
≈The primary purpose of both the IS vibration machine and the EN/ISO jolting apparatus is to provide a standardized, repeatable mechanical method for compacting cement mortar specimens to a consistent density for strength testing.
≈Both IS and international standards provide an automated alternative to manual compaction (tamping), aiming to reduce operator-dependent variability in test results.
≈Both standards tightly control key operational parameters of the machine, such as frequency/cycles, mass of moving parts, and compaction duration, to ensure comparability of results between different laboratories.
