Mini Voltage And Current Tester Detector Mobile Power Capacity Tester Lcd Backlight
Description:
This UV Aging Test Lamp is developed to carry out artificial light source aging tests on industrial products. It is suitable for materials used in the jewelry, watchmaking, and eyewear industries.
With a high - quality reflector and efficient light - emitting diodes, it can simulate the combined effects of sunlight, rain, and humidity. The lamp can cause the tested materials to experience problems
such as blurring, loss of gloss, and oxidation, providing valuable information for product development.
Design criteria:
(1) ASTM D4587: Standard Practice for Fluorescent UV-Condensation Exposures of Paint and Related Coatings
(2) ASTM D4799: Standard Practice for Accelerated Weathering Test Conditions and Procedures for Bituminous Materials (Fluorescent UV, Water Spray, and Condensation Method)
(3) ISO 4892-1: Plastics - Methods of Exposure to Laboratory Light Sources - Part 1: General guidance
(4) ISO 4892-3: Plastics - Methods of Exposure to Laboratory Light Sources - Part 3: Fluorescent UV Lamps
(5) ASTM D4329: Standard Practice for Fluorescent UV Exposure of Plastics
(6) AATCC TM186: Weather Resistance: UV Light and Moisture Exposure
Control System:
Control System 5** Utilizes a black anodized aluminum plate to link up with the temperature sensor, and a black - board temperature controller is employed to regulate the heating, ensuring a more stable temperature condition. The radiometer probe is fixed stably to prevent frequent installation and removal activities. The radiation quantity is measured by a dedicated UV irradiometer with high - precision display and measurement accuracy. The radiation intensity is capped at 50W/m². Illumination and condensation can be controlled independently or in an alternating, circular cycle.

FAQ
1. How to ensure the temperature control accuracy of the test chamber?
The test chamber is usually equipped with high - precision temperature sensors and advanced temperature control systems. Through real - time monitoring and feedback adjustment, the temperature inside the chamber is ensured to be maintained within the set range, so as to ensure the accuracy and reliability of the test results.
2. What is the replacement cycle of the ultraviolet lamps?
The replacement cycle of ultraviolet lamps depends on factors such as the frequency of use and the setting of light intensity. Generally speaking, when a significant decrease in the radiation intensity of the lamp is observed, or the usage time reaches the replacement time recommended by the manufacturer, the lamp needs to be replaced in a timely manner.
3. After the test is completed, how to deal with the test samples?
After the test is completed, the samples should be processed according to the test objectives and requirements. If it is to evaluate the degree of material aging, a detailed appearance inspection, performance testing, and other analyses of the samples are required. If they are no longer needed, they should be disposed of in accordance with relevant waste disposal regulations.
