Jolting Machine Calibration(IS 10078 — Drop Height & Rate)
Calibration of cement mortar cube jolting apparatus — drop height, jolting rate and count verified against IS 10078 so cement strength results stay comparable between labs.

Overview
What is Jolting Machine Calibration?
Cement compressive strength per IS 4031 rests on mortar cubes compacted by a jolting apparatus built to IS 10078:1982 — a defined table mass, a precise drop height and a fixed jolting rate. Worn cams and loose linkages change the drop height and rate, changing compaction energy and shifting strength results between labs testing identical cement.
Global Lab verifies drop height with traceable dimensional gauges, jolting rate against a calibrated counter/timer, and jolt count per cycle, inspects cam and table condition, and certifies conformity to IS 10078 with as-found values — the check that keeps inter-lab cement results honest.

Test Procedure
How the Jolting Machine Calibration is Conducted
- 1
Mechanical Inspection
Cam wear, table seating and linkage condition are inspected as-found. - 2
Drop Height Measurement
Table drop height is measured with traceable gauges at the specified positions. - 3
Rate & Count Verification
Jolting rate and per-cycle count are verified against calibrated timer/counter references. - 4
Evaluation
All parameters are evaluated against IS 10078 tolerances. - 5
Certification
As-found data and verdicts are issued via Autovity QLMS.
