Gross Leak Test
 All units 100% leak tested in Fluorinert FC-43.

 Hermetically Sealed Package
 Mass spectrometer leak rate less than 2 x 10 -8 Atm. CC/sec. of helium.

 Seal Strength
 20 lbs. max. force perpendicular to top and bottom. Subsequently gross leak tested.

 Bend Test
 Will withstand maximum bend of 90°, referenced to base, for 2 bends. Subsequently gross leak tested.

 Pin Material
 Iron and Nickel - Nickel coated, solder dipped.

 Solvent Resistance
 Isopropyl Alcohol, TrichloroethaneNote 1 - Ultrasonic cleaning not to be used. Note 2 - Unit can be cleaned in only one  solvent listed.

 Marking Ink
 (Epoxy, heat cured)

 Solderability
 The terminals are considered solderable and acceptable for electrical connection if 95% of the cooled solder surface is    uniform and free from breaks and pinholes. The other 5% of the cooled solder surface may show only pinholes, voids, or  rough spots that are not concentrated in one area.

 Maximum Soldering Temperature
 260°C for 10 seconds on leads.

Shock Test
1000 G's, 0.35 ms, 1/2 sine wave, 3 shocks each plane.

 Vibration Test
 10-55 Hz, 0.060" D. A., 55-2000 Hz, 20 G's, duration time 12 hours.

 Temperature Cycle
 5°Cycles from -55°C to +125°C, 1 hour per cycle, 25°C ref.
