This European Standard comprises all valves which are components of the pipeline.
This European Standard specifies valves for pipelines with a maximum operating pressure (MOP) over 16 bar.
Control valves and safety valves are excluded from the scope of this European Standard.
This European Standard specifies requirements and appropriate verification tests carried out during production and for certification purposes to verify that the valves conform to the requirements. A summary of the product and type tests is given in Annex G.
