The final length of the sample before testing will be 2 in plus 24 times the thickness of the sample being tested with the joint located in the middle of the specimen. Samples should be conditioned for 72 hours
15、 after preparation in ambient room temperature and humidity before testing. The test sample geometry may vary as necessary for each test to conform to the specified test method, but any deviations are to be stated in the final report. The test sample geometry, including joint type, must be fully des
16、cribed and documented in the Qualification Report (see Section 5.0). The adhesive application conditions (applied pressure, dwell time, and temperature) should match production conditions as closely as possible and will be fully described in the Qualification Report. The failure mode and failure loa
17、d for each sample will be reported and data summaries, including average values and standard deviations for each test, will be included in the Qualification Report. Any discarded test result must be noted and reasons for discarding the result fully explained in the report. 4.3 Property And Performan
