Analysis of the exposure angle of the aging test of the color fastness tester to sunlight
The light fastness tester is a test instrument for quickly measuring the light fastness and weather fastness of dyes and the light and weather resistance of various substances. (Hong Kong) Co., Ltd. can provide users with solutions. In addition, the R&D engineer said that it is very important to choose an appropriate exposure angle for products that need to be tested for sun aging performance. Only in this way can the scientificity and correctness of the test results be ensured. 45°South: This angle is regarded as a typical outdoor exposure angle, and it is also the angle chosen by many factories. Widely used for materials not selected for specified exposure angles. 5°South: This exposure angle is the exposure angle that is used for automotive products or other materials that specify this angle, or is used as a near-horizontal angle. This small inclination angle allows rainwater moisture to stay on the sample surface. Due to more annual solar radiation received, this inclination is compared to 45°The test will be even harsher. Especially during the summer months, these effects are intensified due to higher temperatures. and 5°The inclination angle will be higher than 45°The angle of inclination collects more condensation and the moisture stays longer. 0°(Horizontal plane): Horizontal exposure is rarely used for flat samples or templates, because a slight 5°The angle of inclination allows the water to flow away. However, this angle is useful for many 3D samples and parts. This exposure angle is also used for some materials that require standing water, such as roofing materials. Latitude angle: 25 north latitude°is the location of the Florida Proving Ground. Latitude 34°is the location of the Arizona Proving Ground. This angle, called the latitude angle, is used to maximize solar radiation. Latitude angles are also widely used in solar installations such as solar heaters. 90°South: This vertical fixed angle is most commonly used for architectural coatings. Vertical exposure angles greatly reduce solar radiation, lower exposure temperatures, and reduce wet time.

Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
