ISO 11507:Artificial ageing exposure of paints and varnishes coatings to fluorescent ultraviolet light and water, as an internationally recognised test standard, provides a scientific method and basis for the assessment of the ageing performance of coatings in a simulated natural environment. The UV Lamp Weathering Test Chamber of Sonacme accurately complies with the ISO 11507 standard, providing an efficient and reliable testing platform for coating manufacturers and research institutes.

Standard Interpretation

ISO 11507：Artificial ageing exposures of coloured paints and varnishes coatings Exposure to fluorescent ultraviolet light and water is an international standard that specifies test methods for coloured paints and varnishes coatings under artificial weathering conditions, in particular exposure to fluorescent ultraviolet light and water.

Accurate simulation to reproduce the natural ageing process

Sonacme Technology's UV Lamp Weathering Test Chamber use advanced UV fluorescent lamp technology to accurately simulate the UV radiation portion of sunlight, especially the UVA-340 and UVB-313 wavelengths specified in the ISO 11507 standard. This simulation is not only limited to spectral similarity, but also to the precise control of radiation intensity, ensuring that the test conditions are highly consistent with the aging process in a natural environment.

Light source: UV-A (wavelength 340nm) or UV-B (wavelength 313nm); 40Wx8 pcs.

Irradiance can be set range: 0.3 W/M2 ~ 1.55 W/M2

Strict compliance with standards to ensure the accuracy of test results

Sonacme Technology understands the importance of the accuracy of test results for product development and quality control. Therefore, Sonacme Technology strictly follows the requirements of ISO 11507 standard in the design, manufacture and testing process of its UV Lamp Weathering Test Chamber. From the selection of light source, calibration of radiation intensity, temperature and humidity control to the setting of the test cycle, each link is carefully designed and strictly controlled to ensure the accuracy and repeatability of the test results.

UV Lamp Weathering Test Chamber is only one of the environmental climate test chambers provided by Sonacme Technology, we have also developed xenon lamp aging test chambers, constant temperature and humidity test chambers, cold and hot shock test chambers and other test equipment in line with international standards, and support customised services.

The UV Lamp Weathering Test Chamber of Sonacme Technology not only meets the requirements of ISO 11507 test methods, but also provides personalised aging test solutions according to customers' different needs, as well as real-time monitoring and recording of data during the test period, providing customers with a full range of services.
