12、tandards, and previously published in EIA-364-39A.) 1 Introduction 1.1 Scope This standard establishes a test method to assess the ability of unmated receptacles and wired mated harness to withstand hydrostatic pressures that are encountered in the undersea environment. 2 Test resources 2.1 Equipmen

13、t The test equipment shall consist of a hydrostatic pressure test vessel fabricated in accordance with the ASME Pressure Vessel Code. The pressure vessel shall be designed to suit the hydrostatic pressure range of the connector or receptacle to be tested. The vessel shall be equipped with a suitable

14、 pump to permit pressurization of the vessel to its required pressure conditions in accordance with 4.2 and table 1. The pressure gage connected to the vessel shall be accurate within plus or minus one percent. The vessel shall include a cover designed for mounting and sealing test flanges to the co

15、ver; see figure 1. 2.2 Material Test media shall be tap water, unless otherwise specified. When a union connector is tested (see figure 2) a dielectric oil shall be located above the water in the pressure vessel to completely immerse the bulkhead connector in oil and the union connector in the water

16、. EIA-364-39B Page 2 EIA-364-39B Page 3 EIA-364-39B Page 4 3 Test specimen 3.1 Description A test specimen shall consist of the following: 3.1.1 An unmated receptacle. 3.1.2 A mated bulkhead connector, or a mated union connector; see figure 2. 3.1.3 A protective cover. 3.2 Preparation Three types of

17、 hydrostatic pressure tests shall be conducted in this test procedure; an unmated receptacle, a mated connector, and a protective cover test. Specimens shall be tested under the specified electrical power with all contacts in connector, or ends of cables or wires connected. Instrumentation may be co

18、nnected to the test specimen via the pressure vessel for electrical performance monitoring. 3.2.1 Unmated receptacle The unmated receptacle shall be mounted to the vessel cover flange using sealing and fastening methods as specified in the referencing document. The face of the web section of the rec

19、eptacle shall be exposed to pressure while this area is completely filled with water. 3.2.2 Mated connector The bulkhead type connector or a union type connector shall be assembled using the wire or cable type, length, size and sealing methods as specified in the referencing document. 3.2.3 Protecti

20、ve cover The test connector shall be installed in the vessel so that the pressure can be applied safely to the cover. The back of the connector shall be suitably protected. Precaution should be taken to assure maximum safety when pressure is applied in various tests. EIA-364-39B Page 5 4 Test proced

21、ure 4.1 Hydrostatic pressure, static The test specimen shall be subjected to the specified test condition of table I. The test specimen shall be subjected to the maximum pressure of each applicable increment for 5 minutes 30 seconds at standard ambient conditions, unless otherwise specified in the r
