GB/T 8437-1998 specifies the method for testing the ability of dyed textiles to resist discoloration caused by sulfur-containing gases such as sulfur dioxide in the atmosphere. The sample is placed in a sealed, humid container containing sodium sulfite at a specified temperature, allowing the released sulfurous gas to act on the sample. The color change grade is then assessed.
