The standard “FORD FLTM BI 168-01 Fluid resistance of chassis and exterior materials for incidental exposure” developed by Ford Motor Company (FORD) describes a procedure for determining the fluid resistance of chassis and exterior materials of vehicles to incidental exposure.
This procedure is used to determine the resistance of parts and materials to incidental contact or occasional exposure to automotive fluids. It is not designed to test the effects of prolonged contact. This method is applicable to painted steel, painted plastic, molded or natural colored plastic parts, and elastomers. The evaluation, Method A, Method B, or both must be specified in the reference specifications.
The equipment used in these tests includes:
All test values stated herein are based on material conditioned in a controlled atmosphere at 24 degrees plus/minus 23 degrees and 2 percent plus/minus 50 percent relative humidity for at least 5 hours prior to testing and tested under the same conditions unless otherwise stated.
Before starting the tests, the sample to be tested is placed in a mechanical convection oven with a temperature of 30 degrees plus/minus 50 degrees for at least 2 minutes. Immediately after the sample is removed from the oven, it is inclined at 10 degrees and 5 mL of test liquid is dropped onto the hot surface at short intervals within one minute. Wait 5 minutes before moving on to the next step.
The test sample is stored horizontally at 24°C for the next 23 hours. The procedure is repeated twice, each time dropping the test liquid onto exactly the same spot. In this way, a total of three applications of the test liquid are made.
The sample is evaluated 72 hours after completion of the third test cycle. The sample may be washed with mild soap and water using a minimum amount of scrubbing to remove any remaining test fluid. For dynamic seals, CPSC 01.07.02, or other samples where the fluid will not pool on the sample due to size or shape considerations, the drip method in step two may be replaced by a 5-second immersion followed by a 5-second flow period. A 100-mm-long sample is used and 50 mm of the sample is immersed in the test fluid for 5 seconds. Excess fluid is allowed to drain from the sample for 5 seconds before proceeding to step three.
The evaluation is done as follows:
For skinned view elements, Method A and Method B can be specified.
The chemicals, materials, parts and equipment referenced in this standard must be used and handled appropriately. Each party is responsible for determining appropriate use and handling in their facilities.
Among the numerous tests, measurements, analyses and evaluation studies that our organization has carried out for businesses in various sectors, our organization also provides testing services defined in the standard “FORD FLTM BI 168-01 Fluid resistance of chassis and external materials for incidental exposure” with its trained and expert staff and advanced technological equipment.
