7、t Assemblies A. For Oiled Surfaces 1. Prepare panels or buttons for 10 test assemblies as shown in Figures 1, 2, or 3 in accordance with FLTM BZ 150-11 or described in the Engineering Material Specification. 2. Apply a sufficient quantity of the material under test to one part of the assembly, so th

Cure 5 of each type assembly in accordance with the minimum curing cycle and 5 of each type assembly in accordance with the maximum curing cycle as outlined in FLTM BV 150-05, Table 2. 5. Remove the test specimens from the oven, cool to room temperature and then remove the

Condition the assemblies at room temperature for an open-time of 10 minutes. 4. Cure 5 of each type assembly in accordance with

13、the minimum curing cycle and 5 of each type assembly in accordance with the maximum curing cycle outlined in FLTM BV 150-05, Table 2. 5. Remove the assemblies from the oven, cool to 23 +/- 2 C, and then remove the spacers and clamps. 6. Test and examine as described under the Procedure. Conditioning

14、 and Test Conditions All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. Procedure The tests outlined in M

15、ethods “A“, “B“, and “C“ must be carried out after conditioning the assemblies for 2 h at 23 +/- 2 C and an additional conditioning time of 25 - 30 minutes at the following temperatures (the tests must be conducted at these temperatures): 1. 20 +/- 2 C or, 2. 90 +/- 2 C or, 3. -40 +/- 2 C respective

FORD LABORATORY TEST METHODBV 154-03Printed copies are uncontrolled Copyright 2007, Ford Global Technologies, LLC Page 4 of 7 Method “A“ - Tensile Adhesion - (5 assemblies required for each cure/surface condition). 1. Mount the a

17、ssemblies as shown in Figure 1, in a suitable fixture and insert in the tensile machine, taking care not to load the assembly during mounting. 2. Determine the tensile adhesion N/m2of the assembly by tearing it at a constant speed of 25 mm/minute. Method “B“ - Shear Adhesion - (5 assemblies as requi

18、red for each cure/surface condition). 1. Mount the assembly as shown in Figure 2 in the tensile machine, taking care not to load the assembly during mounting. 2. Determine the shear adhesion N/m2of the assembly by tearing it at a constant speed of 25 mm/minute. Method “C“ - Peel Adhesion - (5 assemb

19、lies required for each cure/surface condition). Note: A flat surface must be obtained before curing. After curing only the squeezed material from both sides of the test assemblies must be removed using a spatula or knife. 1. Mount the assembly as shown in Figure 3, in the tensile machine, taking car

20、e not to load the assembly during mounting. 2. Determine the peel adhesion N/m of the assembly by tearing it at a constant speed of 25 mm/minute. Peel strength is defined as the initial peak load (N) divided by the specimen width (in meters). Evaluation Report the results obtained in N/m or N/m2, as

21、 indicated in Methods A, B, and C, including method of preparation and method of test. Note: All test values as required by the applicable Engineering Materials Specification are based on cohesion failure only, i.e., adhesion strength of the material must be greater than its cohesion strength.
