Preparing for ISO 105-B02 testing: from method to instrument setup

The Light Fastness Tester models TNG1032 and TNG1036 are suitable for compliance with ISO 105-B02, providing accurate and repeatable results through their precise irradiance control and temperature regulation.
Confirming the Method Code

Before procurement, it is essential to confirm that the testing method aligns with ISO 105-B02. This standard outlines procedures for evaluating the light fastness of textiles, ensuring that the testing conditions replicate real-world exposure. The Light Fastness Tester models TNG1032 and TNG1036 are specifically designed for this purpose, offering the required light source and environmental controls. The irradiance range of 0.80 to 1.50W/m² at 420nm ensures that the light exposure is consistent with the standard's specifications, while the irradiance accuracy of ±0.02W/m² at 420nm supports reliable and repeatable measurements.
Identifying the Required Measuring Range
The Light Fastness Tester must be capable of simulating the light exposure conditions specified in ISO 105-B02. The TNG1032 and TNG1036 models use a 2500W air-cooled long-arc xenon lamp, which closely mimics natural sunlight. This light source is critical for accurately assessing how materials degrade under prolonged exposure to light. Additionally, the temperature range of 25 to 50°C with a resolution of 0.1°C ensures that the testing environment can be precisely controlled, matching the standard's requirements for temperature stability. These specifications are vital for maintaining the integrity of the test results and ensuring compliance with the standard.
Checking the Published Specification Table

When evaluating the Light Fastness Tester models, it is important to review the published specifications to ensure they meet the requirements of ISO 105-B02. The TNG1032 and TNG1036 models both offer a sample holder that supports ISO/GB 16 Pcs and AATCC 8 Pcs, accommodating a variety of sample sizes. This flexibility is essential for testing different materials and ensuring that the test setup is appropriate for the samples being evaluated. The digital set and automatic closed-loop compensation features further enhance the precision of the irradiance control, ensuring that the light exposure remains within the specified range throughout the test. These specifications collectively support the accurate and reliable execution of the ISO 105-B02 standard.
Requesting a Quotation
To proceed with procurement, it is necessary to request a quotation that includes the required specifications for the Light Fastness Tester. Ensure that the quotation clearly states the model numbers, irradiance range, irradiance accuracy, light source, and temperature range. This information is critical for verifying that the instrument meets the requirements of ISO 105-B02. By confirming these details, you can ensure that the selected instrument will provide accurate and repeatable results, supporting the testing process and compliance with the standard.
