Such radiators are made with several elements with coolin
18、g channels connected in parallel. This standard defines the overall dimensions and ensures the mechanical interchangeability achieving the same thermal performances. 2 Normative references Addition to EN 50216-1: ISO 4406 1999 Hydraulic fluid power - Fluids - Method for coding the level of contamina
19、tion by solid particles 3 Manufacturing prescription 3.1 Radiator types defined in this document The designations to identify the types of radiator are FA radiators with square flanges and elements of unequal length (see Figure 1) FG radiators with square flanges and elements of equal length (see Fi
20、gure 2) FTR radiators with square flanges and elements of equal length and with several elements with 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) FTT tan
21、gential radiators with square flanges and elements of equal length (see Figure 6) 3.2 General characteristics The main radiator components are headers, connection flanges, elements. The headers shall be made in such a way to guarantee a complete filling and a complete draining. Oblique elements or r
22、educed 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 device on the bottom header. 3.3 Material The radiator elements shall be made of stamped steel plates or steel pipes (round or ovaled) with
23、a thickness of 1,2 mm, in conformity with ISO, EN or equivalent standards. Other thicknesses may be applicable.- 5 - EN 50216-6:2002 3.4 Dimensions and tolerances To ensure interchangeability between radiators of different manufacturers, the tolerances given in the figures shall be maintained. The r
24、adiators shall not deflect from horizontal by more than 2 mm per meter without oil. The radiators shall be vacuum resistant if required. 3.5 Lifting attachments and mechanical connections 3.5.1 Lifting attachments The radiators shall have a lifting attachment. This lifting attachment shall have at l
25、east one lifting lug consisting of a hole with a diameter not less than 30 mm. 3.5.2 Mechanical connections A facility to make a mechanical connection between radiators shall be provided. 3.6 Surface protection 3.6.1 Internal surfaces The internal surfaces shall be free of foreign bodies and transfo
26、rmer oil contaminants according to IEC 60296. They shall be washed with oil for transformers according to ISO 4406. The oil shall conform to IEC 60296. An appropriate velocity of the oil during the washing operation is required. If the cooling liquid is different from transformer oil according to IE
27、C 60296, the radiators shall be treated in agreement with the purchaser. Internal painting shall be as agreed between the manufacturer and the purchaser. 3.6.2 External surfaces The process of anti-rust treatment and painting shall be agreed between manufacturer and purchaser. Due regard is to be pa
28、id to environmental conditions. The environmental conditions shall be according to EN 60721-3-4. 4 Tests 4.1 Routine tests 4.1.1 Visual inspection of surfaces 4.1.1.1 External surfaces When carrying out the visual inspection, there shall be no excessive flexibility and deformations. Fillers of any n
29、ature are not acceptable.EN 50216-6:2002 - 6 - 4.1.1.2 Internal surfaces The inspection shall be carried out by visual means where possible and then in addition by flushing using a filter to detect the presence of any foreign bodies or contaminations. If this inspection is not satisfactory, further
30、flushing shall be carried out. 4.1.2 Leakage test The leakage test shall be carried out according to one of the following two methods. Other methods with other testing values may be carried out by agreement between manufacturer and purchaser. 4.1.2.1 Test with oil The radiators are filled with trans
31、former oil at a temperature of (60 5) C and are kept at a pressure of 200 kPa for 3 h. There shall be no oil leaks. Compliance is checked by visual inspection. 4.1.2.2 Test with compressed air The radiators are filled with air at a pressure of 200 kPa. There shall be no air leaks, however small. Com
32、pliance is checked by immersing the radiator in a tank filled with water. 4.2 Type tests 4.2.1 Inspection of the external paint The paint thickness shall be checked by means of a scratch thickness gauge in the accessible points and by means of a magnetic thickness gauge in the invisible points. The
33、thickness of the single coats shall comply with that specified when ordering. Regarding the surface protection specified in 3.6, a checker-work test can be applied or another test defined by agreement between manufacturer and purchaser. 5 Preparation for transport and storage Radiators shall be clea
34、n and free of all foreign bodies and other contaminations. Radiator flanges shall be covered to prevent the ingress of contamination during transport or storage and steps shall be taken to ensure that there is no deterioration caused by condensation. All measures shall be taken to avoid mechanical d
