Meeting AATCC TM16 Requirements with GT-D02A-1 Light Fastness Tester

Light fastness is a crucial indicator for measuring the color stability and durability of materials under light exposure. Particularly in the quality control of apparel, home textiles, outdoor fabrics, and functional materials, light fastness testing directly impacts a product's lifespan, appearance retention, and ultimate market acceptance.

The GT-D02A-1 Xenon Arc Light Fastness Tester, with its excellent technical configuration and comprehensive standard compatibility, perfectly meets the testing requirements of AATCC TM16, delivering efficient, accurate and stable light aging testing solutions for various industries.

1: AATCC TM16 Standard Overview

It is applicable for evaluating the light fastness of textiles, colorants, finishing agents and various related materials. Its core principle is to simulate the spectral characteristics of natural sunlight, expose test samples and standard blue wool reference samples in a unified environment, and assess the light fastness grade by comparing color difference changes—ranging from Grade 1 (worst) to Grade 8 (best)—which accurately reflects the material’s ability to resist light-induced fading in practical use.

Meeting AATCC TM16 requirements not only demands precise light source simulation capability of the equipment, but also strict control over key parameters such as irradiance, temperature and humidity, as well as support for complex climate condition simulation—placing high demands on the technical performance of testing equipment. The GT-D02A-1 Xenon weathering tester has been optimized for targeted design, fully covering the core needs of the standard and becoming the preferred equipment for compliant testing in the industry.

2: GT-D02A-1 Xenon light fastness tester How to Precisely Simulate ？

Centered on xenon arc light source technology, the GT-D02A-1 Light fastness testing machine is equipped with multiple precision control systems. From light source simulation and parameter regulation to data collection, it fully matches the requirements of AATCC TM16, ensuring the accuracy and repeatability of test results.

Restoring Natural Light Characteristics

The Xenon arc tester is equipped with a 2500W long-arc xenon lamp, which can accurately simulate the full spectrum of sunlight (ultraviolet, visible light, infrared), perfectly reproducing the spectral characteristic requirements of AATCC TM16 for light sources. Combined with a high-transmittance filter combination system, it adopts filters and filter cartridges with a transmittance of 95%, ensuring light source stability while reducing energy consumption and avoiding stray light interference on test results. Compared with traditional light sources, xenon arc lamps can more truly simulate the aging effect of natural sunlight on materials, making them particularly suitable for the xenon arc lamp irradiation mode required by AATCC TM16.

Meeting Strict Standard Requirements

AATCC TM16 imposes extremely high precision requirements on the control of irradiance, temperature and other parameters during testing. The GT-D02A-1 Textile light fastness tester is standard equipped with a 420nm wavelength detection module, supporting digital setting, real-time monitoring and closed-loop automatic adjustment of irradiance.

GT-D02A-1 Light Fastness Tester is fully compatible with a range of international and national standards, including GB/T 8427, GB/T 8430, ISO 105-B02/B04, ISO 12040, ASTM D5010, JIS L0843 and M&S C09/C09A.

Humanized Design

The 7-inch color touch screen supports multiple test monitoring modes (animation, figures and charts), featuring simple operation and intuitive data display for easy mastery by operators.

Adopting light conversion technology, the equipment’s testing and radio transmission are powered without additional power supply, achieving energy-saving operation.

GT-D02A-1 tester reliably meets AATCC TM16 requirements and other authoritative standards. It helps enterprises improve product quality, enhance market competitiveness and gain recognition in the global market.

FAQs on Light Fastness Testing

Q1: What advanced lightfastness testing methods are emerging?

Emerging methods focus on full-spectrum calibrated xenon arc testing (with precise filter combinations and closed-loop irradiance control), intelligent parameterized testing (real-time multi-indicator monitoring + automatic fault diagnosis), and standard-aligned innovation (adapting to updated standards).

Q2: How do xenon arc and UV testers differ?

Xenon arc testers simulate full sunlight (UV, visible, infrared) for comprehensive weathering. UV testers only cover UV segments, for quick UV aging tests. Xenon arc offers higher real-scenario correlation, while UV testers are faster but narrow in simulation scope.

Q3: What are some alternative lightfastness testing methods?

Alternatives include natural climate aging (long-cycle, real-environment verification), carbon arc lamp testing (early method, gradually replaced by xenon arc), and light-corrosion synergy testing (combining light with salt spray/humidity for harsh-environment materials).
