Physical and Environment Characteristics:

Item	Condition of test	Performance requirements
Mechanical Shock	Resonator shall be measured after 3 times random dropping from the height of 60cm onto hard wooden broad of thickness more than 30mm	No visible damage, and measured Values shall meet Table 1
Vibration	Subject resonator to following vibration: Frequency::10～55Hz Amplitude:1.5mm Duration:3 mutually perpendicular planes in each 2 hours Direction:X Y and Z axis	No visible damage, and measured Values shall meet Table 1
Terminal Strength Terminal Pulling Terminal Bending	Force of 5N is applied to each lead in axial direction for 30±5 sec. When force of 5N is applied to each lead in axial direction, the lead shall folded up 90o from the axial direction and folded back to the axial direction. The speed of folding shall be each 3 seconds.	No visible damage, and measured Values shall meet Table 1
Solder ability	Lead terminals are immersed up to 2mm from Resonator’s body in soldering bath of 235±5℃ for 2±0.5 sec.	More than 95％ of the terminal surface of the resonator shall be covered with fresh solder
Resistance to Soldering Heat	Lead terminals are immersed up to 2mm from Resonator’s body in soldering bath of 260±10℃ for 10±0.5 seconds and then resonator shall be measured after being placed in natural conditions for 2 hours.	No visible damage, and measured Values shall meet Table 1
Temperature Cycling	Subject the resonator to -20℃ for 30 min, followed by a high temperature of +80℃ for 30 min. Cycling shall be repeated 5 times. resonator shall be measured after being placed in natural conditions for 2 hours.	No visible damage, and measured Values shall meet Table 1
Heat Resistance	Subject the resonator to +85℃±5℃ for 96 hours, resonator shall be measured after being placed in natural conditions for 2 hours.	No visible damage, and measured Values shall meet Table 1
