Precautions for the use of AATCC stained gray card

It is used to evaluate the discoloration and staining in the color fastness test. It is divided into 1-5 grades, with half-step increments, and is packed in a packaging sleeve. This series of gray cards are internationally accepted 5 grades and 9 grades. The gray scale of the gray card is made with the colorimetric data provided by ISO, AATCC, and GB through careful color matching. The colorimetric data of each file is measured with an imported high-precision spectrophotometer and corrected with the colorimetric transmission standard of the Chinese Academy of Metrology to ensure that its grayscale data is consistent with international standards. Applicable fields: As the gray card is calibrated with the colorimetric data standards specified by the international standard ISO, American standard AATCC and my country's national standard GB, the color fastness grade evaluated by the gray card is consistent with the international standards. This gray card is suitable for the color fastness rating of textiles in GB, ISO, AATCC, DIN, BS, JIS, EN standards. Precautions for use 1. Keep the gray card clean. 2. Always check whether there are fingerprints such as fingers on the gray card. 3. If it is found that the imprint has interfered with the rating, the gray 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.

This article explains why CE certification is non-negotiable (ensuring EU safety/quality standards), outlines essential test items (abrasion, cut, thermal protection per EN 388/EN 407), highlights core instruments (GESTER GT-KC28 TDM Cut Tester, GT-KC29 Cutting Tester, GT-C101 Heat Contact Machine), and details how to evaluate suppliers (20+ years of experience, partnerships with SGS/Bureau Veritas, ISO 9001 certification, after-sales support). It also covers the benefits of OEM/ODM capabilities for customized solutions. Ultimately, partnering with trusted manufacturers like GESTER ensures high-precision, compliant testing to protect workers and meet global market requirements.
What Are the Test Methods for Fabric Bursting Strength?
Fabric bursting strength measures resistance to rupture under concentrated load. Three primary test methods are used:

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,
