EN10208 Standard Specification for Steel pipes for pipelines for combustible fluids. It includes two different technical delivery conditions of EN 10208-1 with Class A,and EN10208-2 with Class B.
EN10208-1 specifies the technical delivery conditions for seamless and welded steel pipes for the on land transport of combustible fluids primarily in gas supply systems but excluding pipeline applications in the petroleum and natural gas industries. It includes less stringent quality and testing requirements than those in EN 1 0208-2.
