Practical Notes

This cylinder measure is specifically for use with the test method outlined in IS 4031 (Part 11).

Ensure the internal surfaces are smooth and free from pitting or dents to allow for accurate volume measurement and easy cleaning.

Regular calibration is necessary to verify the 'as-contained' volume remains within the 400 ± 4 ml tolerance.
