(CE Marking) is a mandatory conformity marking for certain products sold within the European Economic Area (EEA) since 1985. The CE marking is also found on products sold outside the EEA that are manufactured in, or designed to be sold in, the EEA. This makes the CE marking recognizable worldwide even to people who are not familiar with the European Economic Area. It is in that sense similar to the FCC Declaration of Conformity used on certain electronic devices sold in the United States.
ISO 5211
This standard defines a standardized interface system between industrial valves and the part turn actuators used operate them. It details the dimensional requirements for both the mounting flanges on both devices as well as the driving and driven components. This standardization simplifies the design of or eliminates the need for interface components between part turn valves and actuators.
CRN

ABS
ABS, the American Bureau of Shipping offers several different reviews which reduce the amount of review required for the use of a product in a specific application related to ABS class vessels. An ABS Product Design Assessment (PDA) is the assessment of a product for use on a variety of ABS-classed ships following a technical evaluation. The PDA reduces the turnaround time for approval on a specific ship. When a specific ship is chosen, ABS technical staff verifies that the product is suitable for use after a review of the PDA. On an even higher level of approval, achieving ABS Type Approval for a product grants that the product can be selected by ship designers, builders and owners to be placed aboard an ABS-classed vessel.
