Application of UV aging test chamber in home appliance testing

The purpose of UV aging testing of household appliances is to evaluate their weather resistance and durability to determine their service life and performance performance under long-term exposure to solar radiation and other climatic conditions. The test can be performed using a UV aging test chamber.

Uv irradiation may have the following effects on household appliances:

Fading: UV irradiation can cause the color of the appliance housing or panel surface to fade or fade.

Deformation: Long-term UV irradiation may cause deformation of household appliance materials, such as deformation, warping or distortion of plastic materials.

Loss of function: UV irradiation may lead to a decline in the functional performance of home appliance components, such as electronic component failure, loose interface connection, etc.

Surface quality change: UV irradiation can cause cracks, oxidation or pulverization on the surface of the home appliance shell.

Industry standards
The industry standards in line with the UV aging test of household appliances mainly include the following two:

IEC 60068-2-5: This standard specifies methods and procedures for solar radiation aging tests of household appliances.

ISO 4892-2: This standard specifies methods and procedures for UV radiation aging testing of plastic materials under laboratory conditions and is applicable to the testing of household appliance components.

Specific application cases
TV sets: TV sets are often exposed to indoor sunlight. Uv aging tests can evaluate the color stability and surface quality changes of their housing materials.

Refrigerators and washing machines: Refrigerators and washing machine enclosures are frequently exposed to humidity and high temperatures. Uv aging tests can evaluate their weather resistance and appearance quality.

Air conditioner: The outdoor unit part of the air conditioner is often exposed to sunlight, and the UV aging test can evaluate the weather resistance and color stability of its housing material.

Method of test
Using UV aging test chamber to test the aging resistance of household appliances, generally can be carried out according to the following steps:

According to the characteristics and dimensions of actual household appliances, prepare samples that meet the requirements, including shell materials, panels, etc.

Set UV radiation intensity, temperature, humidity and other test conditions according to test requirements or applicable standards.

The appliance samples were placed on the sample stage in the UV aging test chamber to ensure that the samples were exposed to the light source of UV radiation.

According to the set test conditions, the samples were continuously exposed to UV radiation and other test conditions for a certain period of time.

Regularly observe and evaluate the changes of samples, including color change, surface condition, functional performance, etc., and record and record relevant data.

The aging resistance and expected life of the appliances were evaluated based on the sample changes and performance losses observed during the test.

North and South tide tips: specific test steps and parameter Settings should be adjusted and confirmed according to test standards, characteristics of household appliances and actual needs. It is recommended to refer to applicable standards and relevant equipment instructions before performing UV aging tests to ensure the accuracy and reliability of the tests.
