ISO 105-B02 tester models and their published ranges

The Light Fastness Tester models TNG1032 and TNG1036 are both designed to meet the requirements of ISO 105-B02 for colour fastness to light testing, offering precise control over irradiance, temperature, and sample handling.

Specifications and Compliance with ISO 105-B02

Both TNG1032 and TNG1036 are engineered to align with the ISO 105-B02 standard, which evaluates the light fastness of textiles and other materials. A critical specification for compliance is the irradiance level, which is set at 0.80 to 1.50 W/m² at 420 nm. This range ensures that the light exposure is consistent with the standard’s requirements for simulating natural sunlight. Additionally, the irradiance accuracy of ± 0.02 W/m² at 420 nm helps ensure that the test results are reliable and repeatable, essential for meeting the precision demands of ISO 105-B02.

Another key specification is the light source, which both models use—a 2500W air-cooled long-arc xenon lamp. This type of lamp closely mimics the spectral distribution of sunlight, ensuring that the test conditions are representative of real-world exposure. The xenon lamp's ability to produce a broad spectrum of light is crucial for accurately assessing how materials degrade under natural light conditions, as specified in ISO 105-B02.

Sample Handling and Environmental Control

Both models offer a range of sample holders, including ISO/GB 16 Pcs for samples measuring 175 x 45mm and AATCC 8 Pcs for 175 x 75mm samples. This flexibility in sample handling is important for testing different material types and sizes, ensuring that the test setup can accommodate a variety of samples as required by ISO 105-B02. The ability to hold multiple samples simultaneously also enhances efficiency in laboratory settings.

Temperature control is another vital aspect of the testing process. Both models maintain a temperature range of 25 to 50 ℃ with a resolution of 0.1 ℃. This precision allows for accurate simulation of environmental conditions that can affect light fastness, ensuring that the test results are not influenced by temperature variations. The controlled environment is essential for meeting the standard's requirements for consistent and reproducible testing.

Conclusion and Comparative Overview

While TNG1032 and TNG1036 share identical specifications, their design and application may vary slightly based on user preferences and laboratory requirements. Both models provide the necessary features to comply with ISO 105-B02, ensuring that light fastness testing is conducted accurately and reliably. The combination of precise irradiance control, appropriate light sources, and accurate environmental conditions makes these models suitable for laboratories needing to adhere to international standards for colour fastness testing.
