ESCR TEST
Barrel is kept in direct contact of Sunrays / UV rays for sixty days. No Cracking is observed.
WALL THICKNESS TEST
Barrel is cut axially and circumferentially to measure thickness on 48 different points. Required thickness is maintained.
STACK LOAD TEST
Two barrels filled with water are kept on each other for 28 days. No buckling / deformation is observed in barrel of bottom stack.
Drop Test
Two barrels in each shift is drop tested from 1.2 meters height, as per IS 6312. Barrels are dropped in vertical / horizontal diagonally. No leakage, crack or failure of barrels is observed.
HYDRAULIC TEST
01 kg/cm2 air pressure is applied to water filled barrel for thirty minutes. No rupture / leakage is observed.
AIR LEAKAGE TEST
The drums are subjected to air pressure of 0.2 kg/cm2 for period of 60 seconds. No rupture or leakage is observed.
