    High and Low Temperature Test Standard of PC Plastic Material 1. High temperature test     After being placed at 80±2℃ for 4 hours and at normal temperature for 2 hours, the dimensions, insulation resistance, voltage resistance, key function, and loop resistance meet the normal requirements, and there are no abnormal phenomena such as deformation, warping, and degumming in appearance. The key convex point collapses at high temperature and the press force becomes smaller without assessment. 2. Low temperature test After being placed at -30±2℃ for 4 hours and at normal temperature for 2 hours, the dimensions, insulation resistance, voltage resistance, key function, and loop resistance meet normal requirements, and there are no abnormal phenomena such as deformation, warping, and degumming in appearance. 3. Temperature cycle test Put in 70±2℃ environment for 30 minutes, take out at room temperature for 5 minutes; Leave in -20±2℃ environment for 30 minutes, remove and leave at room temperature for 5 minutes. After such 5 cycles, the dimensions, insulation resistance, voltage resistance, key function, circuit resistance meet the normal requirements, and the appearance of no deformation, warping, degumming and other abnormal phenomena. The key convex point collapses at high temperature and the press force becomes smaller without assessment. 4. Heat resistance After being placed in an environment with a temperature of 40±2℃ and a relative humidity of 93±2%rh for 48 hours, the dimensions, insulation resistance, voltage resistance, key function, and loop resistance meet normal requirements, and the appearance is not deformed, warped, or degumped. The key convex point collapses at high temperature and the press force becomes smaller without assessment.
