      5.3
      Test Conditions. Unless otherwise stated herein, inspections are performed in accordance with
      those specified in MIL-PRF-55310 and MIL-PRF-38534, in that order. Process travelers
      identify the applicable methods, conditions and procedures to be used. Examples of electrical
      test procedures that correspond to MIL-PRF-55310 requirements are shown in Table 3.
      5.4
      Special Tests and Descriptions.
      5.4.1
      Frequency-Temperature Slew. Frequency-Temperature Slew Test has been developed as an
      indicator of higher than normal internal water vapor content. The incremental temperature
      sweep from +125°C to -55°C and back to +125°C records output frequency fluctuations
      emulating the mass loading of moisture deposited on the crystal blank surface. Though not
      replacing a customer’s internal water-vapor content (RGA) requirement, confidence is
      increased without destructively testing otherwise good devices.
      5.4.2
      Burn-in Delta Frequency Aging (in Option D). The frequency measurement for burn-in delta
      measurements is performed at the crystal’s upper turning point temperature where its effects on
      repeatable frequency accuracy are maximized. Dependent on the crystal specified, this
      temperature is typically between +65°C and +85°C, ±0.2°C.
      5.5
      Deliverable Data. The manufacturer supplies the following data, as a minimum, with each lot
      of devices:
      a. Completed assembly and screening lot travelers, including rework history.
      b. Electrical test variables data, identified by unique serial number.
      c. Frequency-Temperature Slew plots, Radiographic films, Group C data and RGA data as
      required by purchase order.
