ACCELERATED AGEING AND UV TESTING

ACCELERATED AGEING / WEATHERING: speeding up the natural ageing of products to predict their performance after a prolonged period of exposure to the elements

When you are designing a new product, you want to know that the design and the specifications will last. If your product is for outdoor use, you want to know that it will stand the test of time when it has been exposed to the elements for years.

Accelerated ageing and weathering will help. The tests speed up the ageing process, exposing your product to the elements you know it will face, but in a condensed timescale. The results will give you an indication of how your product will look or perform one, five or even ten years down the line.

If you are still in the design stage, accelerated ageing and weathering tests will help you to choose the materials and coatings that will give you the best results.

At kA Testing Facility, we can provide Xenon Arc testing and the related proving tests for materials and products after exposure. Xenon Arc lamps simulate the full spectrum of natural sunlight, allowing the testing to be as realistic to real world situations as possible. With the ability to fully programme lamp ON/OFF times and use water sprays at any time, we can create most types of climates. Guidance on levels of exposure in relation to particular global regions can be given.

If you need to put your product through specific proving, for example to obtain a specific approval or end-user requirement, our experienced test engineers will work with you to create durations and cycle patterns to meet your individual requirements.

We offer Accelerated Ageing testing to the following standards.

BS EN IEC 60068-2-5
Simulated solar radiation at ground level and guidance for solar radiation testing.

 

Solar radiation testing simulates the effects of weathering on products, materials and coatings that will be exposed to UV radiation, along with other environmental factors such as temperature and humidity. The purpose of the testing is to find out how the product will be affected after a long time spent outside. The testing is sometimes called accelerated ageing testing as it speeds up the ageing process.? 

The testing is carried out in a test chamber, where the environmental factors such as temperature and humidity can be controlled. Xenon arc (UV) lamps are used, which simulate the full spectrum of natural light. Filters can be used to simulate the effects of UV exposure through a window. Our UV test chamber is fully programmable to create test schedules in line with your product standard.

There are numerous procedures given in the standard, each testing for a different effect, including thermal effects, degradation effects or photochemical effects.

 

ISO 4892-2
Plastics – Methods of exposure to laboratory light – Xenon Arc.

 

This standard specifically covers the method for performing accelerated ageing testing on plastics. As above, it seeks to reproduce the weathering effects that the plastic product or material will be exposed to in its everyday use.

After your product has been through the accelerated ageing process, you will want to carry out an assessment. Assessments or further testing will prove the effect the accelerated ageing has had on your product. Whether it is an accurate measure of the change in colour, or a test for the mechanical strength of the material, we offer a range of post-ageing testing.

Some of these tests we carry out are:

Tensile and Flexural testing

Izod and Charpy testing

Cross cut adhesion or cross hatch testing

Colour fastness or light fastness
