Compliance is checked by examination of the construction and of available data regarding the UV resistance characteristics of the ENCLOSURE material and any associated protective coating. If such data is not available, the tests in Table 1 are carried out on the parts.
Samples taken from the parts, or consisting of identical material, are prepared according to the standard for the test to be carried out. They are then conditioned according to Annex C. After conditioning, the samples shall show no signs of significant deterioration, such as crazing or cracking. They are then kept at room ambient conditions for not less than 16 h and not more than 96 h, after which they are tested according to the standard for the relevant test.
In order to evaluate the percent retention of properties after test, samples that have not been conditioned according to Annex C are tested at the same time as the conditioned samples. The retention shall be as specified in Table 1.
8.3 Resistance to corrosion
8.3.1 General
Metallic parts of OUTDOOR ENCLOSURES, with or without protective coatings, shall be resistant to the effects of water-borne contaminants.
Compliance is checked by inspection, by evaluation of data provided by the manufacturer or, if necessary, by the tests and criteria as specified in 8.3.2 through 8.3.4.
Compliance with the applicable performance level (Al, A2 or A3) of IEC 61587-1 is to be considered an acceptable alternative to complying with 8.3.2 through 8.3.4.
