Nominal Size of Pipe	Minimum Thickness of Normal(n)Coating ,in mm
Up to DN100	1.8
Over DN100 up to DN250	2.0
Over DN250 to Below DN500	2.2
From DN500 to Below DN800	2.5
From DN800	3.0
The minimum coating thickness shall be 0.7mm greater (reinforced(v)type)where coatings will be subjected to particularly high mechanical stress. Along any 1m length of pipe,the coating thickness maybe up to 10% less than the minimum required,provded the thinner area does not cover more than 5cm2
