1.9 FES painting supplier shall confirm the receipt paint quality by doing receipt inspection

for all the parameters mentioned in Annexure F & own the responsibility of the quality of

paint used for FES painting. The supplier shall equip himself with the adequate Lab facility

for testing.

2.0 FES Inspection & defect rectification shall be recorded in the FES Painting Inspection

card (Refer Annexure G) for every FES dispatched to Ashok Leyland.
