This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2008, and conflicting national standards shall be withdrawn at the latest by April 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. w w w . b z f x w . c o m EN 150812007 E 4 1 Scope This European Standard provides requirements for metallic mounting kits for part-turn on-off valves and actuator attachments to enable safe and reliable operation. It includes all components transmitting torques from actuators to valves with a maximum flange torque up to 16 000 Nm up to F30 flange type. It applies to part-turn valves and actuators having attachment flanges and drive components as described in EN ISO 5211. It includes recommendations and s for design and environmental corrosion protection. When reference is made to this European Standard, all the requirements apply, unless otherwise agreed between the purchaser and the manufacturer/supplier, prior to order. For the scope of this European Standard, the term “Valve” covers valve or shaft extension top-flange. 2 Normative references The following referenced documents are indispensable for the application of this document.

Special care shall be taken for material selection, in the event of environmental critical conditions. w w w . b z f x w . c o m EN 150812007 E 6 4.3 Design temperature The mounting kit shall be designed for operation at an ambient temperature range between – 20 C and 60 C. 4.4 Environmental corrosion protection Mounting kits shall be protected against corrosion by suitable material selection and/or surface treatment. The manufacturers technical documentation shall specify the choice of the materials and/or the type of the surface treatment. Surface treatment system for carbon or low-alloy steels e.g. according to EN 10025 shall be chosen according to the classification categories given in Table 1. Test assessment and test procedures are the responsibility of the manufacturer. NOTE Table 1 may be used to define the corrosion category and help the mounting kit manufacturers to define the surface treatment for corrosion protection. Table 1 Environmental corrosion categories Typical environments Corrosion category Exterior Interior C2 low Atmospheres with low level of pollution. Mostly rural areas. Unheated buildings where condensation may occur, e.g. depots, sport halls. C3 medium Urban and industrial atmospheres, moderate sulphur dioxide pollution. Coastal areas with low salinity. Production rooms with high humidity and some air pollution, e.g. food-processing plants, laundries, breweries. C4 high Industrial areas and coastal areas with moderate salinity.
