Having a long service life for plastic materials, especially cable compounds, implies high resistance to environmental conditions. The effects of ambient temperature, relative humidity, and precipitation that cable sheaths will be exposed to during their service life directly impact their performance and may lead to a loss of performance over time.
While additives providing UV and moisture resistance in the compound undoubtedly enhance performance, it is necessary to measure how long the product can be preserved.
At Kabkom Chemistry, we use the Q-LAB Q-SUN XE-2-HSE UV Xenon test chamber to simulate the harsh environmental conditions our products may encounter and test their service life and durability.
Tests conducted on our cable sheath products can be performed in accordance with various standards such as EN 50289-4-17, ISO 4892, UL G115, and ASTM D 2565, as agreed upon with our customers.
The products placed in the rotating drum of the chamber are continuously exposed to the xenon arc lamp located in the center of the room. The device operates in cycles, and tests can last for one week or one month according to the applied standard.
The cycles defined in the standards simulate day and night, with the xenon arc lamp emitting constant radiation during the daytime cycles, accompanied by relative humidity and high ambient temperature. During the nighttime cycles, relative humidity and temperature are applied without radiation, and for outdoor products, spraying is also added to the cycles.
