11、) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be repr
12、esented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards ar
13、e drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a
14、 vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 15710 was prepared by Technical Committee ISO/TC 35,

17、 salt solution in a cabinet in order to simulate, in the laboratory, processes occurring in aggressive outdoor conditions. Generally, correlations between such outdoor weathering and laboratory testing cannot be expected because of the large number of factors influencing the breakdown process. Corre
18、lation can only be expected if the effect on the coating of important parameters (e.g. nature of the salt, spectral distribution of the incident radiation in the relevant photochemical region, temperature of the specimen, type and cycle of wetting and relative humidity) is known. In contrast to outd
19、oor weathering, laboratory testing in a cabinet is performed under a reduced number of variables which can be controlled and therefore the effects are more reproducible. The method may also give a means of checking that the quality of a paint or paint system is being maintained. The method has been
20、found to be useful in comparing the alternate immersion/emersion salt solution resistance of different coatings. It is most useful in providing relevant ratings for a series of coated panels exhibiting significant differences in alternate immersion/emersion salt solution resistance. This method is i
21、ntended principally for testing paints used in aerospace applications. The types of conditions specified may occur as an aircraft flies through a variety of environments including sudden changes in temperature and pressure. The results of the test specified in this International Standard will give a
22、n indication of the ability of a paint system to withstand these corrosive atmospheres.
