EN ISO 16961:2015

Petroleum, petrochemical and natural gas industries - Internal coating and lining of steel storage tanks (ISO 16961:2015)

ISO 16961:2015 specifies the minimum requirements for surface preparation, materials, application, inspection and testing of internal coating lining systems that are intended to be applied on internal surfaces of steel storage tanks of crude oil, hydrocarbons and water for corrosion protection.
It covers both new construction and maintenance works of tank internal coating and lining as well as the repair of defective and deteriorated systems.
ISO 16961:2015 also provides the minimum requirements for shop performance testing of the coated/lined samples and the criteria for their approval.
