Xenon lamp aging test uses a xenon arc lamp to simulate the full sunlight spectrum and reproduce destructive light waves in different environments, providing corresponding environmental simulation and accelerated tests for scientific research, product development and quality control. Xenon lamp aging simulates the visible band of sunlight (300^800rm). The common standard is GB/T16422.2-2014 Plastic laboratory light source exposure test methods-Part 2: Xenon arc lamps.

Xenon lamp weather resistance test is an important means to screen formulas and optimize product composition in the scientific research and production process. It is also an important part of product quality inspection. Application materials such as coatings, plastics, aluminum-plastic panels, and automotive safety glass are required to be tested in product standards. Weather resistance test. The xenon lamp weathering test chamber simulates that the main factors causing material aging are sunlight and humidity, and the weather testing machine can simulate the harm caused by sunlight, rain and dew. The xenon lamp weathering test chamber uses xenon lamps to simulate the effect of sunlight, and uses condensed moisture to simulate rainwater and dew. The materials under test are placed in a cycle of alternating light and moisture at a certain temperature for testing. It takes days or weeks to reproduce the hazards that have occurred outdoors for months or even years. Artificial accelerated aging test data can help select new materials, improve existing materials, and evaluate how formula changes affect product durability.

Purpose of xenon lamp aging test

Xenon arc lamps that simulate the full sunlight spectrum are used to reproduce destructive light waves existing in different environments, including visible light, ultraviolet light and infrared light, providing corresponding environmental simulations and accelerated tests for scientific research, product development and quality control.

Application of xenon lamp aging test

Xenon lamp aging test applications include:

(1)Whether product quality passes inspection during R & D and quality inspection;

(2)Ranking of weather resistance performance, or establishing correlation with outdoor natural aging;

(3)Predicting the weather resistance of products when it is difficult to obtain a large amount of outdoor aging test data;

(4)Screening test for similar products

Xenon lamp aging factors

Generally speaking, the simultaneous action of light, temperature, and humidity will have an impact on the accelerated aging of products.

1. Illumination: Daylight can be divided into ultraviolet light, visible light, and infrared light due to different wavelengths. Generally speaking, ultraviolet radiation has a relatively large impact on objects. Coatings and plastic products directly exposed to ultraviolet light will age faster. For materials that are not very stable, even if exposed to visible light or infrared light, Aging will also occur, like some pigments and dye products. Xenon lamp aging test is a test that can simulate the full solar spectrum, including ultraviolet (UV), visible light and infrared (IR). The xenon lamp spectrum basically matches the spectrum of sunlight in the range of 295nm to 800nm, which can accelerate aging.

2. Temperature: Generally speaking, the higher the temperature, the more active the molecules of the material exposed to high temperatures. At the same time, it is combined with ultraviolet radiation to accelerate aging. At a certain ultraviolet intensity, the higher the temperature, the greater the damage to the material. Therefore, during testing, the aging of materials is often accelerated by raising the temperature in the working room of the xenon lamp aging test chamber.

3. Humidity: A humid environment promotes the aging of materials. In the natural environment, rain, dew and humidity in the air will play a corresponding role in the aging of materials, and dew plays a decisive role. The xenon lamp aging test chamber can simulate various humidity environments during the test process to accelerate the aging of materials.
