UL accreditation and testing

As is well known, UL94 is the most universal standard for evaluating the flame retardant performance of plastic parts. The UL yellow card refers to the data obtained through UL testing and certification regarding the flame retardancy, insulation, and safety of materials. Foam products can only undergo flame retardant testing and other related tests conducted by UL laboratory; Through the first factory audit of the IPI by the UL audit department, it was verified that the production plant has advanced production capabilities and stable quality control capabilities; And monitor the consistency of products through periodic FUS quarterly inspections conducted by the UL sampling department on the factory; To obtain UL certification and obtain a yellow card. The relevant information of approved products is publicly available on the yellow card and updated in real-time based on the sampling situation. At the same time, third-party testing agencies such as SGS, ITS, and Huace can also issue flame retardant testing reports for foam samples based on UL94 standards, but this report is only a flame retardant testing report for the tested samples; Not recognized by UL. Guangmai silicone foam GM-400 has obtained UL certification, with a flame retardant level of V0 and UL file number E499089.
