1、FORD LABORATORY TEST METHOD BN 113-02 Date Action RESISTANCE TO HEAT AGING OF BONDED TRIM ASSEMBLIES Revisions Application 2001 O9 11 Revised Editorial - no technical change A. Cockman 1991 O1 24 This procedure is used to test heat-bonded trim assemblies for separation or loosening of the bonded are
2、as or loss in loft of the assembly when subjected to an accelerated heat aging cycle. The test simulates paint repair ovens or severe field aging conditions. Apparatus Required Oven Mechanical convection oven capable of maintaining: 70 +I- 2 “C 80 +I- 2 “C 95 +I- 2 “C Conditioning and Test Condition
3、s All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +I- 2 “C and 50 +I- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. Procedure 1. Place the bonded assembly in an oven a
4、nd expose for the following cycles: 30 minutes at 70 +I- 2 “C 30 minutes at 80 +I- 2 “C 30 minutes at 95 +I- 2 “C 2. Examine and report any loosening or separation of the bonds or loss in loft 10 minutes after each exposure or as specified in the applicable Engineering Material Specifications. 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.
