ISO 105-B02 FAQ: instruments, ranges and method scope
The Light Fastness Tester models TNG1032 and TNG1036 are designed to meet the requirements of ISO 105-B02 for colour fastness to light testing, ensuring accurate and repeatable results through precise irradiance control and environmental simulation.
How do the TNG1032 and TNG1036 models support ISO 105-B02 testing?
The TNG1032 and TNG1036 models are specifically designed to comply with ISO 105-B02, which outlines the procedures for determining the light fastness of textiles. These instruments provide precise irradiance control, with a range of 0.80 to 1.50W/m² at 420nm, ensuring that the light exposure is consistent with the standard's requirements. The irradiance accuracy of ±0.02W/m² at 420nm further supports the standard's need for reliable and repeatable test results.
What are the key specifications of the TNG1032 Light Fastness Tester?
The TNG1032 Light Fastness Tester features a 2500W air-cooled long-arc xenon lamp as its light source, which accurately simulates sunlight conditions. This lamp is essential for replicating the natural light exposure that textiles undergo, as specified in ISO 105-B02. Additionally, the instrument can maintain a temperature range of 25 to 50°C with a resolution of 0.1°C, allowing precise control over the environmental conditions during testing.
What are the key specifications of the TNG1036 Light Fastness Tester?
The TNG1036 Light Fastness Tester shares the same light source and irradiance control as the TNG1032 model. It also includes a sample holder that can accommodate both ISO/GB 16 Pcs and AATCC 8 Pcs, allowing for a variety of sample sizes. The temperature range of 25 to 50°C with a resolution of 0.1°C ensures that the testing environment is tightly controlled, meeting the stringent requirements of ISO 105-B02.
How do the sample holders in TNG1032 and TNG1036 support testing to ISO 105-B02?
The sample holders in both TNG1032 and TNG1036 are designed to hold samples of different sizes, including 175 x 45mm for ISO/GB 16 Pcs and 175 x 75mm for AATCC 8 Pcs. This flexibility ensures that the instruments can accommodate a wide range of sample types, aligning with the standard's requirements for testing various textile materials. The precise positioning and secure holding of samples contribute to the accuracy and reliability of the test results.
