The JSA JIS C 60068-2-85 standard specifies a method for long-time historical replication vibration testing (Test Fj) to evaluate the functional and structural integrity of electronic assemblies under dynamic loads. This test verifies the durability of samples under specific time-historical vibration conditions by simulating a complex vibration environment in actual use. The standard is suitable for application scenarios where specific transient, periodic or random vibration needs to be simulated, such as transport, mechanical impact, or high complexity vibration environments. The testing process includes initial detection, vibration response inspection, functional testing, and final inspection to ensure that the sample remains functional after vibration.
