The technical indicators of this standard are formulated with reference to the standard for heat-resistant chemicals (· The technical indicators of this standard are formulated with reference to the standard (first edition) P3. Its color, shape, density and capsule value are basically consistent with the FCC (first edition). The FCC standard stipulates that the content of 392 substances is not harmful to the product. The technical standard is based on the actual production and use history of domestic products, and stipulates that the content of 98.0% is required. In Appendix A, a method for determining the content of heat-resistant substances by gas chromatography-mass spectrometry is added for the reference of users. Appendix A of the standard is a reminder.||tt| |This standard is supervised by the Quality Standards Department of China Light Industry Association.
