EN 50216-6:2002- 4 -1ScopeEN 50216-6 covers radiators, i.e. the thermal exchangers for the oil cooling with naturalambient air circulation. Such radiators are made with several elements with cooling channelsconnected in parallel.This standard defines the overall dimensions and ensures the mechanical interchangeabilityachieving the same thermal performances.2Normative referencesAddition to EN 50216-1:ISO 44061999Hydraulic fluid power - Fluids - Method for coding the level ofcontamination by solid particles3Manufacturing prescription3.1Radiator types defined in this documentThe designations to identify the types of radiator areFA radiators with square flanges and elements of unequal length (see Figure 1)FG radiators with square flanges and elements of equal length (see Figure 2)FTRradiators with square flanges and elements of equal length and with several elementswith reduced width (see Figure 3)FTTO tangential radiators with oval flanges and elements of equal length (see Figure 4)FR radiators with square flanges with lowered upper header (see Figure 5)FTTtangential radiators with square flanges and elements of equal length (see Figure 6)3.2General characteristicsThe main radiator components are headers, connection flanges, elements.The headers shall be made in such a way to guarantee a complete filling and a completedraining. Oblique elements or reduced elements are acceptable.The layout is given in Figures 1 to 6.The radiators shall be provided with an air vent device on the top header and a draining deviceon the bottom header.3.3MaterialThe radiator elements shall be made of stamped steel plates or steel pipes (round or ovaled)with a thickness of 1,2 mm, in conformity with ISO, EN or equivalent standards. Otherthicknesses may be applicable.SIST EN 50216-6:2002



- 5 -EN 50216-6:20023.4Dimensions and tolerancesTo ensure interchangeability between radiators of different manufacturers, the tolerancesgiven in the figures shall be maintained.The radiators shall not deflect from horizontal by more than 2 mm per meter without oil.The radiators shall be vacuum resistant if required.3.5Lifting attachments and mechanical connections3.5.1Lifting attachmentsThe radiators shall have a lifting attachment. This lifting attachment shall have at least onelifting lug consisting of a hole with a diameter not less than 30 mm.3.5.2Mechanical connectionsA facility to make a mechanical connection between radiators shall be provided.3.6Surface protection3.6.1Internal surfacesThe internal surfaces shall be free of foreign bodies and transformer oil contaminantsaccording to IEC 60296.They shall be washed with oil for transformers according to ISO 4406. The oil shall conform toIEC 60296.An appropriate velocity of the oil during the washing operation is required.If the cooling liquid is different from transformer oil according to IEC 60296, the radiators shallbe treated in agreement with the purchaser.Internal painting shall be as agreed between the manufacturer and the purchaser.3.6.2External surfacesThe pr
