How do I determine the test time for the Xenon Arc Weatherometer?

How do I determine the test time for the Xenon Arc Weatherometer?

SOURCE:

Xenon Arc Weatherometers reproduce weathering damage by sunlight, temperature, humidity and water spray. 
 
When Xenon Arc Weatherometer is in operation, customers often want to know how long the accelerated weathering test should be conducted to correspond to 5, 8, 10 years, etc. It can be clearly said that there is no such correspondence, which is due to the diversity of materials, the diversity of material formulations, climate diversity and many other complex factors, and the conditions of the Xenon Arc Weatherometer test are relatively fixed, but it is just a number of cycles of the same test conditions. So, what to do at this point? There are several methods for reference.
Xenon Arc Weatherometer
1, refer to the relevant product standards
 
Many products or materials manufacturers have made provisions for the aging test time in their product standards, we just need to test according to the standard time and conditions, many international standards, national standards and industry standards also have specific provisions for reference.
 
2、According to the existing correlation conversion formula for projection
 
Artificial accelerated aging and natural exposure correlation research has been in progress, there are also many conversion formula, but only limited to specific materials, if it happens that you happen to, then congratulations, you can project to a relatively reliable use of years.

The secret of stable UV Accelerated Weathering Tester operation 1, the specification of  UV Accelerated Weathering Tester  placement site and location: in the installation of equipment in the site is not just the size of the site, in addition to the temperature, humidity and other conditions must be met, the site can not store flammable and explosive and fire-prone hazardous materials, when the site to meet the requirements, the installation location of the equipment also has requirements, as the equipment in operation will be Generate heat dissipation, so you can not stack items around the equipment, so as not to affect the test results, in addition to the site around the emergency treatment facilities such as fire extinguishing, in order to avoid unwanted accidents lead to serious consequences. 2, try to avoid improper operation: such as improper operation, the light may lead to inaccurate results, due to excessive weight may lead to failure, etc., so the operator should mas...

How to eliminate the safety hazards of xenon lamp test chamber? How to eliminate the xenon lamp test chamber safety hazards? xenon lamp test chamber has the following safety protection systems. 1. refrigeration system: leak detection test, compressor overheating, compressor overpressure; 2. Humidification system: heating tube dry burn, abnormal water supply, water shortage alarm; 3. Circuit system: over temperature protection, fan motor overheating, overall equipment under phase / reverse phase, overall equipment timing, leakage protection, overload and short circuit protection. When installing the xenon lamp test chamber, pay attention to the following points to ensure personal safety: 1. Power supply: The power supply of the equipment uses a three-phase five-wire system, and the equipment cable is four-core wire, three phase wires, and one neutral wire. Please pay attention to the distinction between neutral wires. Because part of the load and control system of the equipment is singl...

Tips for choosing an Ozone ageing chamber

图片
Tips for choosing an Ozone ageing chamber : The choice of environmental temperature: some products need to be tested in a temperature environment of minus degrees Celsius ozone resistance test, some are tested at room temperature, and some are tested at high temperatures. Users just need to understand their own products to test the common test temperature can be. It is important to note that testing at room temperature is more common. Conditions can be placed in the Ozone aging chamber premises equipped with air conditioning systems, it is recommended that users choose the test chamber with a refrigeration system when purchasing, to avoid the summer test, the temperature is too high resulting in inaccurate results. Chamber volume selection: because the Ozone aging chamber chamber materials and ozone concentration control accuracy difficulties will have a corresponding increase, so as long as the test products can be accommodated on, too large chamber will only cause waste.
