The UV resistant cable ties meet the ISO 4892-2 standard: Plastics u2013 Synthetic irradiation or weathering in equipment u2013 part 2: xenon-arc lamps. 1000 hours of irradiation or weathering using this test method is required by the IEC 62275, EN 62275 and UL 62275 standards for UV-resistant cable ties.

This test procedure involves a short test. This test cannot be extrapolated in accordance with the actual service life of cable ties under irradiation or weathering with UV lights. A number of factors may impair the degree of correlation between short tests with laboratory light sources and the actual exposure to external light sources under real operating conditions:

a) Differences in the spectral distribution of laboratory light sources and daylight;

b) Weathering or irradiation periods in which ongoing weathering or irradiation with light from a laboratory light source without any periods of darkness is used;

c) Weathering or irradiation conditions under which very frequent changes between high and low test temperatures arise or unrealistic temperature shocks are created;

d) Unrealistically high or low humidity level;

e) Lack of biological agents or pollutants.
