The UV aging test chamber can accurately simulate ultraviolet light in the sunlight spectrum, which is often the cause of the failure of food colorants, flavorings and flavors in food and beverages. Compared with the xenon lamp aging test chamber, the UV aging test chamber can perform tests faster. The sample holder, like the xenon lamp aging test chamber, can be used to place containers of various specifications.
The UV aging test chamber uses ultraviolet fluorescent lamps that simulate the UV spectrum of sunlight, combined with temperature control and humidity supply devices, to conduct climate change tests on materials to evaluate the weather resistance of the materials.
Applicable standards:
ASTMD4329, ASTMD4587, ASTMD4799, ASTMD5208, ASTMG151, ASTMG154, EN927-6, EN1297, EN1898FIBC, EN12224, EN13523-10, ISO4892-1, ISO4892-3, ISO11507, ISO11895, ISO11997-2, SAEJ202 0.prEN1062-4
The main parameters:
1. 8 40-watt UV fluorescent lamp tubes;
2. Radiation uniformity: covering 4% of the entire sample surface;

4. Ultraviolet wavelength: 290nm~400nm;
5. Test time: 0~9990H adjustable;
6. Blackboard temperature range: UV stage – BPT35-80°C (95-176°F); condensation stage – BPT35-60°C (95-140°F);
7. Sample capacity: 48 + BPT on 24 sample holders;
8. Spray water pressure: 25-40psi (1.7-2.7bar), purity: less than 1ppm dissolved solids, silicon: less than 0.1ppm, conductivity: less than 5us/cm or 200 kilohms;
9. Condensate water requirements: Pressure: 2-60psi (0.1-4.1bra); Purity: Deionized water is recommended, but not required.
UV aging test chambers can help customers accurately reproduce a variety of potential aging modes, including:
1. Fading and discoloration;
2. Deterioration of sourness and other flavors;
3. Loss of protective performance of packaging materials.
Food and beverage photostability test items:
1. Product labels: The light stability of product labels is an important requirement for the food and beverage industry;
2. Food coloring: Food coloring is usually an expensive ingredient in beverage formulations, and optimizing the use of food coloring can increase profitability;
3. Product storage methods: Products are not always displayed indoors for sale, so many manufacturers also test their products outdoors;
4. Color: Color is an important factor in distinguishing many beverages. Fading will cause consumers to misunderstand the product.
