  7. Employ and maintain a drawing and change control system per customers' requirements.
  8. Package for assured safe delivery, considering configuration and destination, unless otherwise specified or controlled by customer.


  1. PURPOSE: To provide a procedure for control of incoming material.
  2. SCOPE: All raw material, purchased parts and sub-contracted processing.
  3. Information such as manufacturing standards, military specifications, drawings and other pertinent data will be maintained by inspection for reference. (Drawing and change control, page 14.)
  4. Special processing of raw material will be accompanied by chemical and/or physical certifications to specific blue-print requirements.

    5.1 All materials received will be certified as to chemical analysis, heat treat or any other requirements of purchase order of drawings.

    5.2 All certifications for material received will be kept on file along with purchase order for which the material was intended.

    5.3 Under no circumstances will material be used on any job if it cannot be identified with certification.

    5.4 If for any reason material should be used from one job to another, a copy of the certification will be forwarded to that particular file.

    5.5 A receiving log will be kept on all incoming materials received for the purpose of manufacturing production parts. At a minimum the receiving log will include:

    1. Purchase order number that the material was ordered for.
    2. Certification Received (Yes or No)
    3. Date Received
    4. Accept or reject
    5. If Rejected (Reason)
    6. Signature of Receiver
    7. Quantity Received
    8. Material Lot Number

  6. If material does not meet all specifications or if certification is not received, it will go to the M.R.B. area immediately for disposition.
  7. If the material is acceptable to all specifications, it will then be put into the material storage area. At that time it will be identified with purchase order number and customer.


  • A first article Inspection Report shall be conducted on the first manufactured lots of parts per each part number. A part will be selected at random and tagged for identification. The results will then be recorded in a First Article inspection Report Form or inspection report pending the contractual agreement of the customer.
  • First Article inspection Report Forms shall be reviewed by a Quality Assurance Representative before shipment. All First Article Inspection Reports will be filed in the job folders and kept on file for (7) seven years.
  • A First Article Inspection report will be done again if a drawing change has been made or the manufacturing process has been changed. Only those characteristics affected will need to be re-inspected.


  • A detailed inspection plan shall be prepared for each part number pending customer requirements of contract. It will identify the inspection requirements and techniques, as well as providing a plan to record the results of our findings.
  • If used, the detailed inspection plan shall be approved by a Quality Representative prior to the First Article Inspection and shipment. Any drawing changes made, are dimensional characteristics, shall be reviewed by a Quality Representative for update.


  1. To insure proper control of work in-process, production control will issue manufacturing planning sheets for each job (Traveler). Inspection points will be specified and space provided for first article acceptance stamping.
  2. Should conditions indicate the requirement for screening at any point in process, the entire lot will be inspected.
  3. Changes to manufactures plans are made by authorized personnel only, identified by stamp and date.
  4. Inspection records will be reviewed and maintained for seven (7) years.


    1. Assure correct material is used.
    2. Conduct First Article Inspection after each operation by stamping area provided on traveler.
    3. Assure proper instruments are being used and that they are calibration dated.
  5. Outside processing will be performed in compliance with specifications which include using customer approved sources.
  6. First Article samples will be delivered to the customer for approval, unless source witnessed.
  7. Production will not begin until customer approval of First Article, when required.


  1. Each lot of production will be inspected per Mil - STD - 105D sampling plan or per amended Dodge-Romig sampling table when required by Customer. All dimensional inspection will be performed prior to processing. visual and dimensional inspection when coatings affected tolerances will be accomplished after processing. In support, inspection must have the completed in-process traveler, purchase order and applicable drawing(s) and specifications.
  2. The parts and travelers will be stamped to indicate acceptance and the quantity rejected, if applicable.
  3. Rejected parts will be stamped and forwarded to the material review board.
  4. Accepted parts will be forwarded to shipping.
  5. A daily log will be maintained by final inspection showing part number, number of pieces accepted and rejected.
  6. All inspection records will be retained for a period of seven (7) years.


  1. Shipping inspection will be responsible for final identification of all production parts, including conformance to customer conditions and specifications, packaging and destinations.
  2. Assurance that necessary individual part processes have been applied, i.e., magnetic particle, penetrant, zyglo, heat treat have been accomplished as dictated by the required certification.
  3. Emberton's Machine & Tool. Inc. will package for assured safe delivery considering configuration and destination, unless otherwise specified or controlled by customer.


  1. To be supported by certifications:
    1. Penetrant inspection.
