JIS K7124-1

Test Materials: In accordance with JIS K7124-1, the primary test materials include adhesive samples and substrates to which they will be applied. These substrates are typically chosen based on the intended application of the adhesive and may include metals, plastics, or other relevant materials. It is crucial that the surfaces are prepared properly to ensure consistent test results.

Test Process: The testing process outlined in JIS K7124-1 involves applying the adhesive to the prepared substrate and allowing it to cure under specified conditions. The adhesive bond is then subjected to a shear or tensile force at a controlled rate using a testing machine. The conditions, such as temperature and humidity, must be maintained as specified to ensure accuracy.

Test Result Interpretation: Results from the JIS K7124-1 tests are interpreted by measuring the force required to break the adhesive bond. The failure mode—whether adhesive failure, cohesive failure, or substrate failure—provides insight into the adhesive’s performance. High force values typically indicate strong adhesion, while lower values may suggest weaknesses that could impact the adhesive’s application in real-world scenarios.
