d. all .062 holes are present and intersect with .116 diameter holes in flash tube, P/N 10551453
e. there is metal between the two longitudinal .116 diameter holes in flash tube, P/N 10551453
4.3.4 Leak test. Each initiator shall be subjected to specified pressure differential. The method for
determining airtightness shall be with a helium mass spectrometer. The helium leak rate shall be converted
to standard cubic inches air. Failure to comply with the requirements of 3.7 shall be cause for rejection of
the cartridge.
4.3.5 Functional.
4.3.5.1 Ballistics. The test sample shall be rigidly supported in the fixture. The sample shall be
tested within 5 minutes after removal from the temperature conditioning chamber. When this time limit is
exceeded, the sample unit shall be reconditioned in accordance with 4.3.5.2.
4.3.5.2 Temperature conditioning. Each assembled initiator shall be conditioned for not less than 4
hours nor greater than 24 hours. When reconditioning initiators at -60°F, all condensation shall be
removed from the exterior surfaces before returning the initiator to the conditioning chamber.
4.4 Inspection of packaging. The sampling and inspection of the packaging, packing, and container
marking shall be in accordance with section 5.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the
contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor
personnel, these personnel need to contact the responsible packaging activity to ascertain packaging
requirements. Packaging requirements are maintained by the Inventory Control Point's packaging activities
within the Military Service or Defense Agency, or within the military service's system commands.
Packaging data retrieval is available from the managing Military Department's or Defense Agency's
automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.
6. NOTES
(This section contains information of a general or explanatory nature that may be helpful but is not
mandatory.)
6.1 Intended use. The initiator assembly is used in conjunction with other propellant actuated
devices in Aircrew Emergency Escape Systems. Since the initiator assembly was developed solely for use
in military aircraft, there is no commercial application.
6.2 Acquisition requirements. Acquisition documents must specify the following:
a. Title, number, and revision letter of this specification
b. Issue of DODISS to be cited in the solicitation and, if required, the specific issue of individual
documents referenced
c. Production test activity and lot size (see 4.1 and 4.2.1)
