IOGP S616 package is a specification  which aims at  defining a minimum common set of supplementary requirements for procurement of line pipe to API Specification 5L 46th Edition 2018 (including Errata 1 2018) and ISO 3183 4th Edition 2019 for application in the petroleum and natural gas industries. The package consists of a main specification, a data sheet LPMDS, a quality  supplementary requirement and an information supplementary requirement document. This set of documents reflects the views of the IOCs which participated in the elaboration of the document.

General agreement amongst most of the IOC and important NOC (who signed the document early January 2019) is to use this document in lieu of their own specification as soon as possible.
