It standardizes the criteria for the materials, equipment and offshore structures for petrochemical, petroleum and natural gas industries. PSL 1 and PSL 2 are the two Product Specification Levels that have been recognized by the technical committee. PSL 1 includes pipes that are made of a standard quality whereas PSL 2 pipes have additional chemical & mechanical properties and their testing requirements also differ.
