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
