Title:         CONTROL, CALIBRATION AND MAINTENANCE OF
          INSPECTION, MEASURING AND TEST EQUIPMENT

Policy:   All instruments for testing and measurement equipment
          used in production or testing will be regulated under
          a calibration program as part of a total Quality
          Assurance program.

Purpose:  This procedure establishes a standard method for the
          use, calibration, recordkeeping and maintenance of
          mechanical measuring tools such as micrometers,
          calipers, etc., and testing instruments.

Scope:    All measuring tools being used to set specifications
          or measure conformance to specifications, such as
          micrometers, calipers, pressure gauges, etc., will be
          included in the calibration program.  This program
          shall also be mandatory for equipment provided by
          suppliers or subcontractors or any personally owned
          Measuring and Test Equipment used by employees at the
          Company's facilities.  Each tool will be assigned a
          number and checked every six months (unless otherwise
          noted) for accuracy.  If you suspect a tool is damaged
          or out of calibration, it should be removed from
          service and brought to the Quality Control Lab (QC)
          for checking.  To enter a tool in the program, take it
          to QC where a number will be assigned and initial
          accuracy checked and recorded.

Definitions:

     1.   Calibration - Comparison of a Measurement standard or
          instrument of known accuracy with another standard or
          instrument to detect, correlate, report or eliminate
          by adjustment any variation in the accuracy of the
          item being compared.

     2.   Inspection, Measuring and Test Equipment - All devices
          used to collect data and measure, gauge, test, inspect
          or otherwise examine items to determine compliance
          with specifications.

     3.   Reference Standard - Standards of the highest accuracy
          order in a calibration system which establish the
          basic accuracy values for that system.
CONTROL, CALIBRATION AND MAINTENANCE OF              Page 2 of 6
INSPECTION, MEASURING AND TEST EQUIPMENT


     4.   Working Standard - Designated measuring equipment used
          in a calibration system as a medium for transferring
          the basic value of reference standards to lower
          echelon transfer standards or other measuring and test
          equipment.

     5.   Traceability - The ability to relate individual
          measurement results to national standards or
          nationally accepted measurement systems through an
          unbroken chain of comparisons.

Procedures:

1.0  Storage, Handling and Maintenance

1.1  Inspection, measuring and test equipment and measurement
     standards shall be calibrated and utilized in an
     environment controlled to the extent necessary to assure
     continued measurements of required accuracy giving due
     consideration to temperature, humidity, vibration,
     cleanliness, and other controllable factors affecting
     precision measurement.  When applicable, compensating
     corrections shall be applied to calibration results
     obtained in an environment which departs from standard
     conditions.

1.2  All inspection, measuring and test equipment shall be
     handled, stored and transported in a manner which shall not
     adversely affect the calibration or condition of the
     equipment.

1.3  Each measuring tool or instrument shall be kept clean and
     maintained in a protective container.  If applicable, all
     threads and slides shall be lubricated with a fine tool oil
     to assure free movement.


2.0  Calibration and Recalibration

2.1  Whenever applicable, standards used to calibrate equipment
     must be traceable to the National Bureau of Standards (NBS)
     or other recognized standards.

2.2  The following procedures will apply to these types of
     testing and measurement equipment:

CONTROL, CALIBRATION AND MAINTENANCE OF              Page 3 of 6
INSPECTION, MEASURING AND TEST EQUIPMENT


     Measuring Tools: (i.e. Micrometers, Calipers, etc.)

     The calibration shall be done by comparison to standard
     gage blocks traceable to the National Bureau of Standards
     with an accuracy 3 to 10 times greater than that of the
     measuring tool.

     The comparisons shall be made at different points along the
     measuring range of the tool.  The gauge blocks used shall
     be picked at random to assure that the measuring tool is
     not checked at the same points on each calibration cycle.
     When a measurement is made, move the gauge blocks from one
     side of the tool's measuring face to the other on an X/Y
     axis to assure no wear or taper exists on the measuring
     faces.


     Pneumatic Testing Instruments (e.g., Pressure and Vacuum
     Gauges, Flowmeters, etc.) and Electrical Test Equipment
     (e.g., Multimeters, Non-Invasive Evaluator or Radiation
     Outputs, etc.)


     Calibration shall be achieved through a contract
     calibration laboratory which in turn uses standards
     traceable to the National Bureau of Standards or other
     recognized standards.

     The contract laboratory should have in place and document
     their applicable calibration controls required or as
     appropriate for the equipment.  For example, the contractor
     should have:

         -     written calibration procedures;
         -     records of calibration;
         -     trained calibration personnel; and
         -     standards traceable to NBS or other independent
          reproducible standards.

     If in-house standards are used by a contractor to calibrate
     device-related measuring equipment, these standards must be
     documented, used, and maintained the same as other
     standards.

2.3  Inspection of Special Tooling

     Special jigs, fixtures, tooling masters, templates,
     patterns, and related devices should be initially proved by
     inspection to ensure that they will produce acceptable
     parts, prior to release to production.
CONTROL, CALIBRATION AND MAINTENANCE OF              Page 4 of 6
INSPECTION, MEASURING AND TEST EQUIPMENT


     The tool should be reinspected at the start of a production
     run, when there has been a change in the manufacturing
     process that affects the design of the tool or the
     dimensions produced from it, or upon expiration of the
     calibration period if the tool is used as inspection media.

     If the tool is used as inspection media, the tool must be
     placed under this calibration program.


3.0  Record Keeping and Labeling

3.1  A Calibration Card (Exhibit 1) will be maintained for each
     piece of testing and measurement equipment under the
     calibration program.

3.2  After calibration, the date of calibration and the next due
     date of calibration shall be recorded on the Calibration
     Card.  The actual calibration reading and any adjustments
     and/or repairs to the tool or instrument should be
     recorded.

3.3  Each piece of testing and measurement equipment will be
     labeled with a decal which contains the date of
     calibration, by whom calibrated and the date the next
     calibration is due.  If it is not practical to attach the
     decal to the tool or instrument, then the decal should be
     placed in the container or shelf/location where the item is
     stored when not in use.

3.4  Measurement tools or instruments not intended for testing
     or manufacturing do not require calibration in accordance
     with these procedures.  These items must be either kept out
     of manufacturing or labeled "Not a Calibrated Instrument"
     to avoid inadvertent use.  Otherwise, these items must be
     entered into this calibration program.


4.0  Recall System

4.1  The Calibration Card will be placed in a 12 month tickler
     file in the month proceeding the next recall due date.  The
     cards in the section of the file for the current month are
     pulled and all of the equipment listed is calibrated.  For
     example, in a six (6) month calibration cycle, when an
     instrument is calibrated in May, the card is moved from the
     May section to the October section of the file.  When the
     file is checked in October, the cycle card will be there to
     remind that calibration is due.  The process is repeated
     until an event such as instrument wear-out occurs and the
     respective cycle card is removed from the file.  The
     calibration Card tickler file will be maintained by the
     Quality Control Manager.

5.0  Out-of-tolerance Conditions

5.1  If a tool or instrument is found to be out of calibration,
     the QC lab will immediately pass the out-of-calibration
     information to the appropriate supervisor in the department
     where the tool is used.  The Department and QC management
     will take appropriate remedial action for affected in-
     process or finished products.


6.0  Control of Subcontractor Calibration

6.1  Purchasing will be responsible for assuring that applicable
     subcontractor's calibration system conforms to the
     applicable product plan requirements and to the degree
     necessary to assure compliance with contractual
     requirements.
