GB/T 39630-2020 "Nano Silver Colloidal Solution" applies to quality inspection and product acceptance of nano silver colloidal solutions for antibacterial purposes. It specifies technical requirements, testing methods, inspection rules, and other relevant content. Testing requires the use of inductively coupled plasma mass spectrometry (ICP-MS) to determine total silver content and impurity content, laser particle size analyzers to analyze average particle size and particle size distribution, and ultraviolet-visible spectrophotometers to detect related optical characteristics. Additionally, antibacterial tests must be conducted to evaluate the antibacterial rate against Escherichia coli and Staphylococcus aureus, ensuring the product's antibacterial performance and safety.
