It includes guidelines, recommendations and s for enclosure and corrosion protection, control and testing. It does not apply to pneumatic actuators which are integral parts of control valves. Other requirements, or conditions of use, different from those indicated in this document, should be subject to negotiations, between the purchaser and the manufacturer/supplier, prior to order. The terms and definitions applicable to this European Standard are given in EN 15714-1. 2 Normative references The following referenced documents are indispensable for the application of this document.
