2、 AND CONNECTORS ON AUTOMOTIVE GLASS OR COATED POLYCARBONATE SUBSTRATE Application These procedures are used to determine the adhesion properties of connectors when adhered to automotive glass or coated polycarbonate substrate. A shear test and a tension test will be administered. Apparatus Required

3、Mechanical Testing Equipment The mechanical testing equipment must be able to apply a tension force at a rate of 125 +/-25 mm/min. An example of the mechanical testing equipment is shown below in Figure 1. Figure 1 Load Cell A load cell no larger than 455 kg is to be used. Pull Wire For the tension

4、test in section two, wire or similar material that can be threaded through the connector and made to mate with the load cell portion of the test equipment will be needed. The only requirement is that the wire or similar material be able to withstand the 100 N tension force it will transmit to the te

FORD LABORATORY TEST METHOD BU 155-01 Copyright 2018, Ford Global Technologies, LLC Page 2 of 8 Test Samples Plaques for the tension test must be prepared with a connector that is pre-drilled such that pull-wire can be threaded through the connector. Sample Preparation Preparing the sam

For the tension test, pre-drilling the connector should also be done according to the manufacturers recommendations. Conditioning and Test Condit

7、ions 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.
