Apart from color matching Lab, which ensures consistency of color and regulates shade variation, HFL container division is also equipped with a QC lab which checks container for various quality parameters like :

Handle pull test - Drum rested in downward position on a bracket and weight loaded on the handle to check the strength.

Drop Test - Drum dropped from 1.28 Meter height (Filled with 98% water) and checked for any leakage. Only a few drums are checked on random basis.

Air pressure Test - Drum is immersed in water & air is passed from the mouth of the drum at a pressure of 0.40 Kg/cm2 for 5 sec. Air Bubbles will come to show the leakage.

Scratch/Mar Resistance - Checked manually by scratching the paint with index & thumb finger. Formation of any scratches are then observed visually. This test is carried out after painting and printing.
