27、btain data on the corrosion resistance of metals, alloys1), metallic and other inorganic coatings in atmospheric environments, to evaluate the type of corrosion of particular metals, and to obtain data for corrosivity determination and estimation. It involves exposure of the specimens to the action
28、of atmospheric environments at the test sites, and periodic checking of the test specimens. It does not cover service corrosion testing. The corrosion rate of the specified metal depends on the environment of the atmospheric corrosion test site. The relationship between corrosion rates for metals an
29、d atmospheric variables is complex. Therefore, the results of field tests cannot be used to predict service performance exactly, but do provide an approximate guidance to service performance. 1) Hereinafter referred to as “metals”. 4DIN EN ISO 8565:2011-09 EN ISO 8565:2011 (E) 1 Scope This Internati
30、onal Standard establishes general requirements for stationary corrosion testing of metals and metallic and other inorganic coatings under atmospheric conditions carried out in the open air or under shelters. It can also be applied for testing of complex specimens and assemblies of metallic materials

35、to corrosion tests 3 Requirements for test specimens 3.1 Types of specimen 3.1.1 Flat sheet specimens Rectangular specimens in the form of flat sheets are the preferred type as they can be readily weighed and measured, and their simple shape facilitates attachment to test frames. A convenient specim
36、en size is 150 mm 100 mm. Specimens may be of different size provided that they can be accurately evaluated. The specimen thickness shall be adequate to ensure that the specimens will survive the intended test period. The 5DIN EN ISO 8565:2011-09 EN ISO 8565:2011 (E) specimen thickness shall also ta
37、ke into account the possibility of mechanical effects and of intergranular corrosion in some materials. The most convenient thickness is 1 mm to 3 mm. For specimens with metallic coatings, the surface area of the test specimens should be as large as possible, in any case not less than 50 cm2(5 cm 10
38、 cm). If the coated articles used are smaller than 50 cm2in area, specimens of the same kind may be combined to total the required minimum surface area. However, the results obtained will not necessarily be comparable with those obtained on specially prepared test specimens of the specified minimum
39、area. 3.1.2 Irregularly shaped specimens Other specimen shapes, such as bolts, tubes, rods, angles and even assemblies, may be tested if necessary. The ends of tube specimens shall be sealed if only corrosion of the outside surface is of interest. Complex specimens, such as assemblies, may contain c
40、revices, water traps, welded joints and dissimilar metals. It is therefore important to take account of the effects of these on the corrosion resistance of the assembly. Care should also be taken to position the assembly to simulate its intended use. 3.1.3 Specimens with welded joints Atmospheric co
41、rrosion tests on welded joints are intended to reveal any tendency for preferential corrosion in the weld zone arising from metallurgical or compositional differences between the weld metal and the parent material. The joints shall preferably be placed in the centre of the test specimen, parallel to
42、 its long side (preferred position), or perpendicular. 3.2 Specimen preparation Because atmospheric corrosion tests may extend over many years, it is important to ensure that specimens are clearly identified and records of data are carefully kept. It is normally necessary to cut specimens from large
43、r pieces of the metal to be tested and to carry out deburring. These operations involve the risk of surface damage to the specimens and, with some metals, may lead to significant changes in metallurgical condition (for example, work-hardening of sheared or cut edges). Surface damage can be avoided w
44、ith care, whilst work-hardened edges should be removed by machining, unless the effects of this condition are being specifically evaluated. Similar damage may be caused by other operations, such as flame-cutting, sawing and grinding. When the results of the test are to be compared with service perfo
45、rmance, it is recommended that specimens be exposed with surfaces identical or similar to those, which would apply in service. For all other purposes, a well-defined surface preparation is needed. Surface preparation may involve a combination of a degreasing stage using organic solvents or alkaline
46、degreasing fluids and a mechanical or chemical descaling treatment for surfaces bearing mill scale, heat-treatment scale or rust. Suitable descaling treatments for a wide range of metals are given in ISO 8407. For metallic and other inorganic coatings, it is absolutely necessary to avoid cleaning me
47、thods which may attack the surface of specimens. 3.3 Handling After final surface cleaning before exposure, it is important that limited handling occurs. In general, it is necessary to use clean gloves in the final handling operations. 3.4 Marking of specimens The test specimens may be marked in suc
48、h a way that no confusion during the exposure is possible. Marking shall be legible and durable over the whole period of exposure and shall be made on those areas of the test specimens that are not subjected to visual assessment and have no functional purpose. 6DIN EN ISO 8565:2011-09 EN ISO 8565:2011 (E) Methods suggested for marking are different. The test specimens may be marked with appropriate numbers by stamping. For metallic coatings, the prefer
