Measure after free drop of the RESONATOR three times from the height of 75cm onto a wooden board. Amplitude 1.5mm and 10～60Hz with cycle time 2～3 minutes in 3 direction (X,Y,and Z axis)each for 2 hrs. Measured at room temperature after immersing the lead wire in a soldering bath of 300℃±10℃ for 5 seconds up to a position where it is2mm away from the root of the plug. Apply a load of 500g for 30 seconds in the lead wire's axial direction. Bending cycle : 0゜→ 45゜→ 0゜→ 45゜→ 0゜ Solderability of lead wire A minimum 95% Apply resin-flux contained-solder to a of the area to be soldering iron of 280 ℃ ±5 ℃ for 5 2 coated with seconds. solder 10 Note: 1. The adove tests no. 1 to 9 must be conducted independently (not series tests) 2. *1: Measure after 24 hours soak at room temperature . 3. *2: Measure after 2 hours soak at room temperature . 8. Precautions (1) Temperature for soldering the lead wire shall not exceed 300℃ and the soldering time shall be within 5 seconds. (2) Position to be soldered : Solder only the position where the lead wire is1.0mm away from the glass seal. Do not solder the case. (3) Cutting, bending and correction of lead wire: The glass seal shall be free of any crack or other damage which may deteriorate the characteristics of RESONATORS.
