Water Spray Test - FCA PF.90303 par.5.6.2 - FIAT CHRYSLER

Water spray test standard FIAT CHRYSLER FCA PF.90303 par.5.6.2

This test is performed on grommets in their design-intent position on a Wire Assembly or a portion of a wire assembly. The Test Header rack and Grommet Mounting Panel are specially built by the wiring supplier for this test.

The test samples must represent the maximum and minimum content bundle diameters and be long enough to reach the first retention point on each side of the grommet. The dry side retention point and routing is critical. However, for the wet side, concessions can be made so there is no interference between the wiring and the spray nozzles, provided they are approved by the wiring PC for that vehicle.

The pressure at the water nozzles is regulated to 25-30 PSI, as measured at the nozzle closest to the test header rack supply. Fluorescent dyes may be used to detect water leaks, but may not affect the surface tension of the water.

The grommet mounting panel shall consist of a production representative panel with a production representative stamped aperture for the grommet hole. It is recommended that the mounting panel be constructed in such a manner as to allow the backside of the panel to be sealed off from water overspray (e.g., with flanges).

The spray will be directed from the production intent mounting wet side, and the wiring shall follow the production intent routing and design up to and including the first retention point.

The wiring on the dry side shall follow the production intent orientation, routing, and design up to and including the first retention point on each side of the grommet.

Acceptance Criteria: No water may pass between the grommet seal, the seal plane on the grommet mounting panel, or the grommet to wiring interface. Even a single drop constitutes a failure.

The Grommet Mounting Panel configuration and Test Header Path during spray must be approved by FCA Engineering prior to the start of the test.

The EMCTEST Technologies laboratory is able to conduct this test thanks to its own test device built properly for this FCA procedure test.
