Tests are to be conducted in accordance with test methods outlined in this specification for quality conformance tests (see 4.5.4).  If the tests are being performed at the end of the stated shelf-life to update the shelf-life of the sealing compound, and all test are passed, the shelf-life will be extended and additional three months.  Up to three updating shall be allowed.

4.3.2 Minor variations. Minor variations in applications requirements during quality conformance inspection (see 4.5) may not be cause for rejection if approved by the procuring agency.

4.3.3 Identification of qualification samples. Qualification samples shall be identified as specified herein and forwarded to the activity responsible for qualification testing as designated in the letter of authorization form that activity (see 6.2).

4.4  Qualification  inspection

4.4.1  Qualification tests.  Tests to determine conformance to all technical requirements of this specification are classified as qualification tests and shall be performed prior to or on the initial shipment of sealing compound to a purchaser.  The manufacturer shall use ingredients, manufacturing procedures, processes, and methods of inspection on production sealing compound which are essentially the same as those used on the approved (qualified) sample. If necessary to make any change in the ingredients in type of equipment for processing, or in manufacturing procedures, the manufacturer shall submit for reapproval a statement of the proposed changes in material, processing or both and, when requested, a sample of sealing compound. Production sealing compound made by the revised procedure shall not be shipped prior to receipt of reapproval.

4.4.2  Qualification test samples.  Unless otherwise specified, the qualification test samples shall consist of three 1-quart (1 liter) kits of the compound and 12 sectional-type

(MIL-S-38714) containers. The sectional-type containers shall be the 6 ounce size filled with 3-1/2 ounces of sealing compound. Qualification samples shall be identified as follows
