Each member body interested in a subject for which a technical committee has been established has 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 are drafted in accordance with the rules given in the ISO/lIEC 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 memberbodies casting a 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 StandardISO15710was prepared by Technical CommitteeISO/TC35,Paints and varnishes, SubcommitteeSC9,Generaltestmethodsforpaintsandvarnishes. Annex A forms a normative part of this International Standard. iv @ISO 2002-All rights reserved ISO15710:2002(E) Introduction Coatings of paints, varnishes and similar materials are exposed to alternating wet and dry (humid) cyclic conditions 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. Correlation can only be relative humidity) is known. In contrast to outdoor weathering, laboratory testing in a cabinet is performed under a mayalsogiveameansofcheckingthatthequalityofapaintorpaintsystemisbeingmaintained The method has been 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 differ
