Precautions for the use of AATCC stained grey cards
It is used to evaluate the discoloration and staining in the color fastness test. It is divided into 1-5 grades, and the half grade is incremented. It is packed in the packaging sleeve. This series of gray cards is an international standard type of 5 grades and 9 grades. The grayscale of the gray card adopts the colorimetric data provided by ISO, AATCC and GB, and is made through careful color matching. The colorimetric data of each file is measured by an imported high-precision spectrophotometer, and corrected with the colorimetric transfer benchmark of the Chinese Academy of Metrology to ensure that its grayscale data is consistent with the international. Applicable fields: Since the colorimetric data standards stipulated by the international standard ISO, the American standard AATCC and the Chinese national standard GB are used to calibrate the gray card, the color fastness level evaluated by the gray card is consistent with the international standard. This gray card is suitable for textile color fastness rating in GB, ISO, AATCC, DIN, BS, JIS, EN standards. Precautions for use 1. Keep the gray card clean. 2. The gray card should be checked frequently for marks such as fingers. 3. If it is found that the imprint has interfered with the rating, the grey card must be replaced. 4. Try to avoid mechanical damage caused by touching. 5. If mechanical damage interferes with the rating, it should be replaced. 6. After the gray card is used up, put it into the sleeve.

textile testing equipment can be applied in different ways as tensile tester manufacturers.
Ball Burst Method (ASTM D3787): Steel ball penetration for textiles/films using testers like GT-C02-2.
Hydraulic Method (ISO 13938.1): Fluid pressure on rubber diaphragm for industrial fabrics via GT-C12A.
Pneumatic Method (ISO 13938.2): Compressed air for breathable materials tested with GT-C12B.
Results are influenced by raw materials, yarn properties,
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.
