GB/T 18950 - 2023 Laboratory Light source exposure test for focusing rubber and plastic hoses. The standard specifies the use specifications of various Light source equipment such as Xenon-arc lamps, and details the preparation and Installation methods of hose samples. The test process strictly controls the light intensity, time and temperature Humidity conditions. Through regular observation and measurement, the physical performance changes such as hose Color, Appearance and tensile strength are accurately recorded. This provides a scientific basis for evaluating the durability of the hose in the light environment, and helps manufacturers optimize product design to ensure its reliable use in outdoor lighting scenarios.
