22、raphy . 11 ENISO2810:2004ISO :0182(4002)E iv Foreword ISO (the International Organization for Standardization) 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 memb
23、er body interested in a subject for which a technical committee has been established has the right to be represented 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 Ele
24、ctrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adop
25、ted 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 vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of pate
26、nt rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 2810 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varnishes. This second edition cancels and replaces the first edition (ISO
27、2810:1974), which has been technically revised.

28、n of the type of natural weathering and the natural weathering procedure to be used to determine the resistance of coatings or coating systems (direct weathering or weathering behind window glass). Natural weathering is used to determine the resistance of coatings or coating systems (denoted in the
29、following text simply by coatings) to the suns radiation and the atmosphere. Special atmospheric influences, e.g. industrial pollution, are not taken into account in this International Standard. 2 Normative references The following referenced documents are indispensable for the application of this d

41、Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 durability ability of a coating to resist the deleterious effect of its environment 3.2 time of wetness period during which an exposed coating has visible water present on it 4 General The durabil
42、ity of a coating during natural weathering depends on how, where and when the coating is weathered. Therefore, these parameters and the intended use of the coating shall be taken into account when exposures are carried out. In particular, the following parameters shall be considered: a) The location
43、 of the exposure site, for example industrial, marine, rural. In choosing sites, those which differ markedly in the type or level of pollution from the normal shall be avoided, unless they are appropriate to the intended end use of the coating under test. b) The height, angle and orientation of the
44、exposure rack. These parameters will govern the extent to which the specimens are affected, for example by dew, frost and atmospheric pollutants. c) The nature of the terrain on which the rack is constructed (for example concrete, grass, gravel). The terrain may affect the climatic conditions around
45、 the specimen under test. It would rarely be feasible to select an ENISO2810:2004OSI 1824002:0)E(3 ideal terrain in practice, but the effect of such variations in climatic conditions will be minimized by ensuring that all specimens are situated sufficiently high above the ground (see Clause 5). d) W
46、hether the performance of the coating on the front and/or the back of the specimen is of interest. Certain types of degradation, for example rust formation and/or mould growth, are frequently more severe on the sheltered parts of the specimen. e) The intended use of the coating, including its substr
47、ate, and whether the coating is to be washed or polished in service. The results of tests on an exposure rack will apply precisely only to the environment in which they were obtained. Provided that the test conditions are reasonably appropriate to the intended end use, the relative performance of a
48、number of coatings tested at the same time will enable valid deductions to be drawn. It is recommended that each series of specimens under evaluation include coatings of known performance to act as reference standards. The results of natural weathering may vary according to the time of year during which the tests are carried out. The influence of these variations will be reduced if the exposure period is sufficiently long. The exposure period should be a
