FORD LABORATORY TEST METHOD BI 160-01 Page 3 of 5 Copyright 2003, Ford Global Technologies, Inc. Procedure A. Preparation and Exposure of Panels 1. All test panels
10、are to be permanently identified on the reverse, or back, side in a suitable fashion. Front, or exposed, side marking may be used if it does not infringe on the exposure test area. The reverse side and edges of all ferrous panels are to be sealed for corrosion prevention (electrocoat; clear air dry
11、coating; etc.). 2. One sample of each submission is to be retained by the preparer in a dark place for later comparison use. 3. Expose samples (exposure side up) facing south, at an angle, or angles, described in the applicable Engineering Materials Specification, for the system under consideration.
12、 Use standard panel racks unless otherwise instructed. 4. The test period shall be selected to evaluate the field performance and/or characteristics under consideration (refer to the applicable Engineering Material Specification). 5. During the outdoor exposure, the specimens shall be positioned and
13、 mounted so as not to cast shadows on each other or contact one another. Also, the specimens shall be mounted so that the products of weathering shall not drain off from one specimen onto another. 6. All direct weathering panels and the glass cover over the under-glass exposures shall be rinsed mont
14、hly. Panel rinse being defined as: hosed down with tap water at the end of the morning dew formation. 7. Unless specified otherwise, panels are to be sent for exposure to sites approved by Ford Motor Company. These are: Florida Sites South Florida Test Service - Solar Testing Services Everglades Sit

B. Evaluati
18、on of Painted Panels After Exposure 1. Wash the specimen surface to remove loose and partially embedded dirt. A suitable procedure consists of gentle rubbing with a soft cellulose sponge thoroughly wetted with warm city tap water and a 0.05 % solution of nonionic liquid soap. Rinse immediately under
19、 warm running city tap water. Water droplets should be removed using clean compressed air, to prevent water spotting. 2. Compare the specimen with the retained panel under artificial daylight per FLTM BI 109-01. Note any change in color by using the AATCC Gray Scale. Under the same light, check for
20、cracking, crazing, chalking, or other deterioration. Basecoat/clearcoat colors should be examined using a Berkley Colortran lamp (refer to Apparatus Required). 3. Measure the gloss with a 60 glossmeter (or as specified in the applicable Engineering Material Specification) according to FLTM BI 110-01
21、 on the exposed and unexposed sample and compare with each other. Record the gloss. NOTE: A SLIGHT LOSS OF GLOSS OR CHALKING MAY BE REMOVED ON THE BOTTOM THIRD OF THE PANEL BY HAND POLISHING WITH A SOFT CLOTH USING A MILD POLISHING COMPOUND (see apparatus and materials section). COMPARE THE POLISHED
22、 AREA WITH THE UNEXPOSED SAMPLE. 4. Compare the exposed panel against the retained panel using reflection of overhead ceiling batten light, reflection of North light exterior window bars or Imagery Reflectance Meter and reject any exposed panel showing smokey appearance or giving a Distinction of Im
23、age (DI) value lower than the value specified in the relevant Engineering Document. 5. Where specified, perform water immersion test for 24 h per FLTM BI 104-01. Report any blistering or color change by water immersion. FORD LABORATORY TEST METHOD BI 160-01 Page 5 of 5 Copyright 2003, Ford Global Te
24、chnologies, Inc. C. Evaluation of Color Impregnated Panels After Exposure 1. Wash one third of the specimen surface to remove loose dirt.

Measure the gloss with a 60 glossmeter (or as specified in the applicable Engineering Material Specification) according to FLTM BI 110-01 on the exposed and unexposed sample and compare with e
27、ach other. Record the gloss. 4. Determine the change of properties as defined in the applicable Engineering Material Specification (e.g., tensile test, impact, etc.). Chemicals, materials, parts, and equipment referenced in this document must be used and handled properly. Each party is responsible for determining proper use and handling in its facilities.
