6.7 Inspection sampling propotion
Level II AQL=0.65
7. Flame retardant inspection
Inspection method: Clamp the plastics with pliers and put it into the fire of the alcohol burner at 45 degree angle. Keep 30s and after the plastics are away from the fire and the fire of the plastics will extinguish within 10s. If the plastics are small and burned down within 30s, keep the plastics in the fire for 10s, and the fire will extinguish within 10s.
Inspection quantity: 1pc if the lot is less than 3,000pcs. 2pcs if the lot is more than 3,000pcs (2pcs are from different cartons)
8. Environmental performance inspection:
Inspection method: -40℃~85℃, 4 hours by High and low temperature circulation box
95℃, 4 hours by High temperature chamber
85℃ 85% RH, 4 hours by High temperature and high humidity chamber
-40℃ 4 hours by Low temperaure chamber
Inspection requirement: After the above tests, the plastics surface is smooth and clean, with no crack or deformation.
Inspection quantity: 1pc if the lot is less than 3,000pcs. 2pcs if the lot is more than 3,000pcs (2pcs are from different cartons)
