Then release the resonator into ambient room conditions for 1 hour prior to measurement. Vibration: Subject the resonator to vibration for 1 hour in each of three mutually-0perpendicular planes. Amplitude 1.5mm, 10Hz to 55z. Mechanical Shock: Drop the resonator randomly onto a concrete floor from a height of 1 metre. Three times. Reflow Soldering: Preheating at 150°C to 175°C for one minute. Then expose the resonator to more than 200°C with the maximum temperature not higher than 230°C±5°C. Then release the resonator into ambient room conditrions for 1 hour. Solderability: Dip the resonator terminals no closer than 1.5mm into the solder bath at 230°C±5°C for 5 seconds±1 second. Min. 95% of lead terminals surface shall be covered with solder. High Temperature Exposure: Subject the resonator to 85°C±2°C for 96 hours. Then release the resontor into ambient room conditions for one hour. The resonator shall fulfill the specifications stated in 'Electrical Specifications' above. The resonator shall fulfill the specifications stated in 'Electrical Specifications' above.
