ANSI EIA-364-39B-1999 pdf download Hydrostatic Test Procedure for Electrical Connectors, Contacts and Sockets
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 Equipment
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 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 cover; 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.
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 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 connected 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 receptacle 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 Protective 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. Precaut
