SAE J2412 is a popular and commonly used\u00a0accelerated weathering test standard, which exposes automotive interior\u00a0samples to simulated sunlight using\u00a0xenon lamps.\u00a0<\/strong><\/p>\n

<\/p>\n

In order to test real life performance of a material or product, you need to be able to test it to the environmental conditions which it would expect to be exposed to during its service.\u00a0 This could apply to any material or product which sits outdoors or indoors but still in direct sunlight through a glass window such as the interior of cars.\u00a0 Accelerated weathering simulates these conditions to give an indication of how well the product or material will perform when exposed to elements such as sunlight, moisture and humidity.<\/p>\n

Samples of the product or material are placed inside QSUN Xenon Arc Chambers where they undergo a programme specifically designed to mimic the weathering conditions it is likely to face.\u00a0 There are many automotive standards offering different weathering and light fastness cycles. \u00a0Standard SAEJ 2412 offers a good comprehensive test that is not manufacturer specific and so can be used for a variety of end uses and customers. \u00a0All standards specify weathering condition options. Most have irradiance, wavelength, sample temperature, air temperature and humidity settings, they will also offer cycles including light & dark and wet & dry cycles. These cycles depend on the conditions they are trying to simulate.<\/p>\n

Samples are tested within the QSUN Xenon Arc Chambers for a set period of time which can vary, you can test to a set number of hours or a set number of Kjs, some standards have specific times or Kjs to adhere to others\u00a0would be agreed by the contractual parties prior to testing beginning. The SAEJ test is usually requested in Kjs which we are able to convert into hours so we know how long the test will take. Testing times can be very varied from just 70hrs (110Kjs) up to thousands of hours depending on the requirement.\u00a0Once the testing has been completed the results are evaluated, this can be a visual evaluation and grayscale, colour measurements using our spectrophotometer or gloss readings using a sheen gloss meter.\u00a0 The most common method used to gather results is a visual assessment following the guidelines set by ISO 105 A02. This standard describes the grey scale for determining changes in colour of the samples before and after a specified amount of radiant exposure.<\/p>\n

The main products which are tested to standard SAE J2412 are interior car products including plastics and textiles. \u00a0This can include carpets, seat coverings, parcel shelves, material coverings or anything which could be affected by sunlight. Although primarily used for interior automotive parts the standard can also be used to test car make and model stickers and other exterior parts if the environment is expected to be hot and dry.<\/p>\n

The Q-Lab test chambers, Q-SUN Xenon Arc Chambers: Model Xe-3,\u00a0at\u00a0impact solutions\u00a0are capable of accelerating the ageing process by approximately 8 times.\u00a0\u00a0There are just over 8000hrs in a year so running a test in one of our weathering chambers for just 1000hrs (Around 6 weeks) you will be simulating around a years\u2019 worth of natural weathering. \u00a0This is not an exact number due to the amount of light, heat rain changing yearly so exact numbers are impossible. \u00a0Few industries have\u00a0time to leave samples or components outside for years at a time to get durability results\u00a0so this is the perfect solution for speeding up the weathering process.<\/p>\n

If your product is structural, combined with the weathering testing, we can perform a variety of physical testing which enables us to give you a truer picture of your product\u2019s performance during its expected lifespan.<\/p>\n

Impact Solutions\u00a0have an accelerated weathering and light fastness laboratory and are able to test a wide range of standards including SAE J2412.
