BS EN 50289-4-17:2015描述了三种用于测定护套材料抗紫外线性能的方法 电缆和光缆。这些测试适用于符合以下要求的室外和室内电缆应用: 产品标准。护套样品取自成品电缆。尽管本测试方法主要针对通信电缆，但也可以使用 适用于相关产品标准要求的能源电缆。如果护套由交联（热固性）材料制成，应记住 交联前应制作模制斑块。方法因紫外线源的性质而异。由于失效时间过长，所述方法不适用于含有紫外线的产品 抵抗是由≥ 2.0%的炭黑，满足中规定的分散要求 EN 50290-2-24。交叉引用:EN 16472:2014EN 60811-202IEC 60811-202EN 60811-501IEC 60811-501EN ISO 4892-1:2000ISO 4892-1:1999EN ISO 4892-2:2013ISO 4892-2:2013ISO 9370EN 60068-2-5IEC 60068-2-5EN 60811-100:2012IEC 60811-201IEC 60811-201EN 60811-203IEC 60811-203EN ISO 4892-3:2013IEC出版物第20号，1972购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS EN 50289-4-17:2015 describes three methods to determine the UV resistance of sheath materials for electric and for optical fibre cables. These tests apply for outdoor and indoor cable applications according to the product standard. The samples of sheath are taken from the finished cables.Although this test method European Standard is written principally for communication cables, it may be used for energy cables if called up by the relevant product standard.Where a sheath is of cross-linked (thermosetting) material, it should be recalled that the preparation of moulded plaques should be made before crosslinking.Methods differ by the nature of the UV source.Due to the excessive time to failure, the methods described are inappropriate to products where UV resistance is conferred by ≥ 2,0 % carbon black meeting the dispersion requirements defined in EN 50290-2-24.Cross References:EN 16472:2014EN 60811-202IEC 60811-202EN 60811-501IEC 60811-501EN ISO 4892-1:2000ISO 4892-1:1999EN ISO 4892-2:2013ISO 4892-2:2013ISO 9370EN 60068-2-5IEC 60068-2-5EN 60811-100:2012IEC 60811-100:2012EN 60811-201IEC 60811-201EN 60811-203IEC 60811-203EN ISO 4892-3:2013ISO 4892-3:2013CIE Publication No. 20, 1972All current amendments available at time of purchase are included with the purchase of this document.
