REQUIREMENTS:
Dimensions and conf i gurations: See figures 1 th ru 4. Interface dimensions shall conform to
MIL-DTL-38999, except as noted.
This dummy stowage rec eptacle (DSR) mat es with qualified plugs in accordance with
MIL-DTL-38999/26, MIL-DTL-38999/29, MIL-DTL-38999/30, and MIL-DTL-38999/31.
Air leakage: Testing shall be in accordance with EIA -364-02, except the minimum period of
measurement shall be 10 seconds. The air leakage rate shall be no greater than 1 atmospheri c cubic
inch per hour (4.55 X 10-3 cm3/s) Stowage receptacles shall be mated to connectors having either
contacts or inserts removed so that a pressure of 10 lbft /in2 (.703 Kg/cm2 ) can be applied against the
insides of the stowage receptacles.
Qualification (all classes): Qual ification shall be in accordance with MIL-DTL-38999, conducted on two
samples of each shell size, ex cept only the following sequen ce of tests shall be required:
Examination of product
Coupling torque
Dynamic salt spray (corro sion)
Air leakage (see requirem ent)
Visual and mechanical
Qualification (clas ses J and M only): Qualificati on shall be in accordance with MIL-DTL-38999, except
that in addition t o t he t est sequence specified for all classes above, the f ol l owing tests shall be required:
Temperature cyclin g
Hydrolytic stability
Group A sampling in spection. Sampling for group A inspection shall be as specified in table I.

Shell size code
(for shell size codes A, A1 and A2, see note)
Class
NOTE: Shell size codes A, A1 and A2 for shell size 9 only:
Shell size code A is a univ ers al configuration for us e with plugs with mating key
polarizations A, B, C, D, E and N.
Shell size code A1 is for use with plugs with mating key polarizations C, E or N.
Shell size code A2 is for use with plugs with mating key pol arizations A, B or D.
NOTE: The term PIN is equivalent to the term (part number, identification num ber, and type
designator) which was previously used in this specification.
Application not e:
1. Shell size 9, shell si ze code A (universal c onfiguration), is not recommended for blind mate
applications due t o t he possibility for misalignment between the DSR keyways and the plug key s.
Misalignment can potentially damage plug EMI bands.
Change effectivity. Unless otherwise specified by the preparing activity and/or the qualifying activity, all
changes from the prev i ous revision of this specification sheet shall become effective withi n 90 days of the
date of publicati on of the latest revision. If unable to implement changes within the 90 day t i me period,
the manufacturer or val ue added distributor shall notify the qual ifying activity. The qualifyi ng activity shall
determine if an ext ension may be granted.
Disposition of stock. Unless otherwise specified by the qualify ing activity and coordinated with the
preparing activity, qualified manufacturer s and their selling agent s or distributors may continue t o
ship stowage receptacles w hich were manuf actured in accordan ce wi th the previous revision of this
specification sheet for a period of 18 months from the date of the latest rev ision, provided t hat form, fit
and function are not affected.
Changes from previous issue. The margin s of this specification are marked with vertical lines to indicate
where changes from t he previous issue were made. This was done as a convenience only and t he
Government as sumes no liability whatsoever for any inaccu racies in these notations. B i dders and
contractors are cauti oned to evaluate the requirements of t hi s doc um ent based on the entire content
irrespective of the marginal notations and relationship to the last previous issue.
Class F is not for Navy use. Class F is inactive for use in Air Force new design.
Shell size code A (shell size 9) is inactive for new design. Use shell size codes
A1 or A2 for new design.
